With holiday season being one of the most popular times for people shopping for a new vehicle, you may come across the term CVT Transmission. What does this term mean? And more pointedly, is it something you should buy – or something you should avoid?

CVTs were once derided as the shiftless “rubber band” transmission that made cars seem as if they were revving up forever. But CVTs are no longer a mere experiment by automakers looking for new ways to improve efficiency. They’re becoming so common that it’s hard to find a mainstream manufacturer that doesn’t offer them in at least some models. Audi, Chevrolet, Ford, Honda, Jeep, Nissan, Subaru and Toyota all provide CVTs as the standard transmission in at least one model. And some carmakers have been doing so for many years.

What is CVT?

CVT stands for continuously variable transmission, which is different from a conventional automatic transmission. The standard automatic features a complex series of gears that transmit the power of the engine to the wheels. The CVT, on the other hand, doesn’t have any gears. It features a pair of pulleys of variable width, connected by a belt. One pulley is connected to the engine, the other to the wheels. Because their width is variable, it changes depending on how much power the car needs, hence the term “continuously variable transmission”.

The CVT also works a little differently from a conventional transmission. To a certain extent, you do operate it more or less normally—sliding the shift lever from Park into Drive, then zooming off! From there, though, the CVT gets a little bit more complex.

You see, with ordinary automatics, there are a set number of gears—so, for instance, you may see a vehicle marked as a “6-speed automatic.” Each of these gears accommodates a certain speed range, so as you start driving faster, the car may automatically shift from first gear into second, and maybe then on to the third.

With a continuously variable transmission, though, you do not have all these gears. Actually, you just have one. Unlike the individual gears in an ordinary automatic, this gear can handle all speeds. That’s why they call it variable.

CVT Transmission vs. Automatic

There are several differences between the automatic and continuously variable transmission, apart from the basic functionality of each. Some are more obvious than others. For instance, when you’re driving a vehicle with CVT, you won’t notice or “feel” gears shifting. You’ll just notice the car getting faster or slower. In that sense, it might make for a smoother ride. The unusual thing is that it essentially chooses the ideal speed for any given situation and holds it constant—even if you’re accelerating the car.

Say, for instance, you try to speed up to pass another car. When you slam on the gas, the car will immediately zoom to a nice, brisk speed – but then, it will hold steady at that speed, even as you continue to apply pressure to the gas pedal. So that feeling you get in an ordinary automatic, where you climb through the gears, just isn’t there.

Another difference you may notice, when driving a vehicle like this, is an easier take off. Since there are no gears in a CVT transmission, your vehicle will find it easier to get to the ideal torque ratio and maintain it. This means it will almost effortless for the car to take off from a stoplight, as well as easier to climb even on difficult terrain.

Needless to say, driving a vehicle like this is a unique experience, and it’s becoming more and more popular with some auto manufacturers. Many automakers use CVTs because it can get maximum power out of a small engine, therefore delivering a quicker, more reactive acceleration. This is also the reason why vehicles with four-cylinder engines are often the ones with CVTs.

Cars with continuously variable transmission

Because cars with a continuously variable transmission and ones equipped with a standard automatic look the same, you may not be able to tell the difference when car shopping. But here are the car makes and models that most often use CVT transmissions:

  • Mitsubishi, Nissan & Subaru – these car manufacturers often use continuously variable transmission not just for their regular models, but also for their SUVs.
  • Honda & Toyota – with over a dozen models that feature a CVT transmission, these two Japanese automakers are also on the rise.
  • European manufacturers – although CVTs are more common among Japanese brands. Some European car manufacturers also started adopting it for a few of their models, including Mercedes-Benz A-Class and B-Class, as well as Renault Koleos and Megane.

If you’d like to know what type of transmission a car has before buying it, it’s easy to do for new vehicles, as this is usually printed on the window sticker, but you can also find it on the manufacturer’s website or printed brochure. If you’re buying a used car, then further research may be required, but typing the make, model and year in a search browser should do the trick.

CVT Transmission Problems

But before actually buying a car with this type of transmission, you might want to look into the CVT transmission reliability. Is this the best kind of transmission for your next vehicle? Certainly, there are some advantages:

  • This kind tends to get slightly better gas mileage, especially in city driving. Fuel efficiency is a great advantage of CVTs because they can adjust gear ratios instantaneously. They also have an infinite range. Estimates place an average sedan with CVT transmission at 38 miles per gallon. You’ll also find this type of transmission in most hybrids.
  • The power delivered is simple and straightforward.
  • The ride itself tends to be smooth; you never feel the gears shifting, because, well, they don’t!

But there are also drawbacks, the most common complaint of some drivers being that a continuous variable transmission doesn’t allow for quite as much speed. Also, some drivers prefer the escalating gear shifts to the steady hum of this new technology. Other CVT transmission problems include:

  • Overheating
  • Sudden loss of acceleration
  • Slipping, jerking & shuddering
  • Excessive wear and stretching of the belt
  • Droning sound
  • Cost of repair and maintenance

Ultimately, it’s up to you—but we do recommend that you drive a CVT transmission before you purchase one!

Premium Gas

Buying gas is one of life’s small conundrums. Most of us have little idea what those numbers on the pump mean, so we usually just pick one that seems to correlate best to our stage in life. When we’re starving students, we go for the less expensive 87 octane. If we drive a nice car and we’re feeling flush, bring on the 91! While buying what you can afford might seem like a smart approach, this kind of simple calculation actually misses hidden costs you should be considering. Before we get to those, let’s clarify what octane levels actually are and what they mean for your car. If you are wondering whether high octane fuel equals better fuel economy, you first need an understanding of how fuel interacts with your engine.

Premium Gas

What Are Octane Levels?

Octane actually has two definitions. In its simplest sense, octane is the name of a chemical compound. This flammable hydrocarbon, in combination with several others, is what makes gasoline. When ignited, it powers your car’s engine. The second definition of octane refers to the amount of energy required to ignite the gasoline. These octane level numbers (87, 89, 91, etc.) are a percentage of the fuel’s performance measured against pure (100%) octane. Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock. Knocking occurs when the gasoline is burning fast and is also under high pressure environments. When this occurs there are small gasoline explosions occurring within the engine. These small explosions interfere with the cylinders’ normal operation and can damage engine parts. Ignoring these knocks can result in an expensive repair and reduce your car’s performance significantly.

So Why Use High Octane Fuel?

High octane fuel may prevent engine knock, which is a useful quality in a fuel. This is why luxury cars that use higher-pressure engines sometimes require premium gasoline. Higher octane gasoline reduces knocks and pings in high-pressure environments which exert more energy and burn fuel quicker. If your car manual doesn’t require you to use high octane fuel, using it anyway probably won’t help. Stick with the type of fuel that best suits your car’s engine requirements.

Wait, But What Octane Fuel Should I Use?

Good question. Your car’s owner manual will recommend the fuel you should be using for best performance, and that’s the type to go with. If your manual says unleaded (87) is enough, then it is. If it advises premium (usually 91), then heed its advice.

So is Higher Octane Fuel More Efficient?

In a word, no. On its own paying for premium gasoline does not make your car run better or get greater gas mileage. Giving your car the fuel it requires to run smoothly and efficiently, without damage to the engine, does make a difference in your fuel mileage.

So How Can I Learn to Improve Fuel Economy?

First, get your car serviced regularly. If your engine isn’t in good repair, you can waste fuel. The same holds true if your tires are underinflated, which can reduce fuel efficiency up to 0.3% for every pound of pressure dropped in all four tires, says fueleconomy.gov. And, just as you should use the recommended fuel octane level of your manufacturer, you should also use the right grade of motor oil. Doing so can definitely make your fuel go farther. Second, lighten your load wherever possible. Remove your roof storage rack whenever you aren’t hauling anything, and don’t leave unused cargo sitting there. It adds significant weight to your car, which means you need to burn more gas to go the same distance. You should also regularly clean out your trunk or back cargo area for the same reason. Third, avoid idling while waiting for long periods of time. Although it may seem easier to leave the car running, this wastes a lot of gas, especially if you have the air conditioner on too. When possible, open the window to cool off. And on the highway, use cruise control when possible. By keeping your speed even, you avoid accelerating and decelerating, and save fuel.

Does How I Drive Matter?

Yes, your driving style impacts your fuel economy significantly. We’re not trying to be backseat drivers, but observing the speed limit and driving safely also improves your bottom line. When you accelerate rapidly, step on the brakes, stop and start a lot, and drive at excessive speeds, you waste gas. If you want to preserve the fuel in your tank, the best thing you can do is take a sensible approach to drive.

Fuel economy is a confusing issue, but hopefully this explanation has been enlightening. When in doubt, stick to the recommended octane level in your owner’s manual and you’ll be fine. Aside from that, the best things you can do to stretch your gas mileage are to drive well and service your car regularly, and bring it in whenever something seems wrong. If you notice any trouble with your car, such as funny sounds, pulling, using fuel faster than normal, leaking, or not performing to its usual standard, bring your car into Aamco of Keller today!

When it comes to general maintenance for your car a proper oil change at regularly scheduled intervals is one of the most important things you can do as a vehicle owner. At Aamco of Keller we are commonly asked by our customers “what is the difference between synthetic oil and conventional motor oil”? Our goal is to be your locally owned and trusted Keller Auto & Transmission Repair Shop and to also help educate our customers on any questions they may have regarding their vehicle.

When it comes to motor oil, you have two popular options which include going with conventional motor oil or synthetic motor oil. The differences between the two begin at the molecular level and continue all the way up to how the oil is manufactured and processed. Conventional oil will cost less than the synthetic but will require more frequent oil changes. If you decide to go with the synthetic motor oil – depending on your driving habits it’s recommended that you change your oil every 5,000 to 7,500 miles for most vehicles.

What is Synthetic Motor Oil?

Synthetic oil is nonetheless oil, though it is somewhat man-made. Synthetic oil is made from a base oil, powder additives, and a carrier oil that enforces an even distribution of the additives.

Both synthetic oil and traditional motor oil are made from refining oil. Most synthetics begin with highly refined crude oil, pumped from deep underground. That is the same source as conventional oil. Other synthetic oils use artificially made compounds or a synthetic oil as a base oil. The primary difference between synthetic oil and traditional oil is at the level of refinement.

The base oil falls into one of several “oil grades” from mineral oils extracted from crude (Group I and II) to fully artificial, compound-based oils. All grades of oil are manufactured with additives that increase performance.

Refinement processes and ingredients also result in scientific control over molecular size and purity. That can lower friction, reduce engine sludge, and increase performance. Synthetic oil was first developed in 1929. With technology and access to resources, it has refined to accommodate jets, high-performance vehicles, and everyday consumer vehicles. The need for synthetic oils also comes from technological changes. High-performance vehicles and machinery—from jets that break the sound barrier to industrial plants—have to operate in extreme conditions and temperatures. Highly refined engine oil allows better temperature resistance.

Advantages to Synthetic Oil:

  • Uniform molecular size means less friction
  • Refinement and engineering reduce deposits
  • Additives boost protection and can clean engines
  • Better function in cold and extreme weather
  • Cleaner oil with fewer impurities

Full Synthetic vs. Synthetic Blend

Full synthetic oils are better understood as a grade of motor oil. Semi-refined–also called synthetic blend–oils are less refined than full synthetic oil. Semi-synthetic oil blends traditional oil with the more technologically advanced oils. You get the advantage of additives and more refinement. But, the impurities and inconsistent molecular size of conventional motor oil are still in the blend at lower degrees.

The benefit of synthetic blends is largely a cost-vs-benefit decision. Synthetic blends are cheaper than full synthetic motor oil but higher performance than conventional oil.

How often should you change Synthetic Oil in your car?

Synthetic oil is better on your engine and has fewer impurities, it can go longer than conventional oils or synthetic blends.  It’s important to remember to schedule regular oil change intervals. For conventional oil, twice a year is suggested as a safe way of keeping track. If you want to keep better track, every 7,500 miles is suggested for average cars. You should also change your oil filter every oil change. But, especially if using synthetic oil, every other oil change is sufficient if you don’t regularly push your car hard or endure extreme conditions.

Check your owner’s manual. Newer cars may be able to go 10,000 miles or only need an oil change once a year. Turbo engines and older cars may still require oil changes every 3,000 to 5,000 miles.

Synthetic oil change intervals range 10,000-15,000 miles or once a year (whatever comes first). Extended performance synthetic motor oil is on the upper top of that range. That extra 5,000 miles may be worth the investment.

Synthetic Motor Oil vs. Conventional Motor Oil

Visually speaking you cannot tell the difference between new synthetic and conventional oil. There are two major differences, however. First, how they are made is a distinction. We’ve explained that synthetic oil is far more refined than conventional oil.

Second, the way they run in your car is worlds apart. Used motor oil shows a lot thicker and sludgy in conventional oil vs. synthetic oil, given the same amount of wear. Synthetic oil is by far better for performance. It protects the engine due to lower levels of friction. Additives help clean the engine of deposits. And, fewer impurities mean it burns cleaner, thickens far more slowly, and has fewer deposits to start.

“According to industry tests, synthetic oil engines perform 47% better than engines using conventional motor oil.” – AAA

Choosing the Best Motor Oil for your Vehicle

A full synthetic oil is the best oil option for any engine. Synthetic oil cuts down the hassles or oversights related to more frequent oil changes and deposits.

If synthetic oil is outside your maintenance budget, go with a blend or rotate between a full synthetic and non-full synthetic every other oil change. Changing car oil will not damage your vehicle. Keep a record to remember the mileage, next oil change date, and type of oil.

It’s always best to consult your owner manual to lookup your manufacturer’s recommendations on oil viscosity grade and their recommended oil specifications. If you have trouble locating this information feel free to give our team of experts mechanics at Aamco of Keller a call for their recommendations.

Our goal at Aamco of Keller is to be your locally trusted auto repair experts and to keep you and your vehicle on the road safely. One of the most common general routine car maintenance questions is how often should replace your windshield wiper blades?

You always want to be able to see road conditions as clearly as possible when you’re behind the wheel. Anything that impairs your visibility, whether it be rain, fog, or dust, can ultimately compromise your safety. When you don’t have the proper tools to combat these hazards, the problem can only get worse. Having fully-functional windshield wipers is an absolute necessity for the safe operation of any motor vehicle.

Over time, the blades of your windshield wipers can become less effective due to wear and tear. Most drivers aren’t aware of this until they go to turn their wipers on in the midst of a rainstorm, only to find that their blades have essentially become useless.

When should you replace your Wiper Blades?

Getting a routine auto inspection is a great way to address wiper blade issues before they become too serious. Additionally, you can become more aware of how long wiper blades tend to last and when you should replace them.

So how long do windshield wiper blades tend to last? Obviously this is a generalization and your mileage may vary, but most cars and trucks will need new wiper blades every two to three years. You may need them more frequently than that if you tend to drive in a lot of really hazardous weather conditions.

You can also pay attention to how well your wipers are actually working. If you see streaks across your windshield, that means the wipers are falling apart and it’s time to replace them. If your wipers leave paste on the windshield, that means it is definitely time to invest in new blades!

Increasing the life of your Wiper Blades

With a little bit of routine maintenance, you can actually extend the lifespan of your wiper blades. One thing you can do is wash your windshield regularly, especially removing things like bird droppings or caked-on dirt and grime. This will help spare your blades from having to take on too much.

If your car ends up with snow and ice on it, take a minute to scrape away the build-up around your blades. Forcing your blades to try to cut through layers of ice can cause them to become dulled or corroded well before their time.

Finally, take a few minutes to rub your blades with a clean cloth dipped in just a bit of rubbing alcohol. This is a small and easy way in which you can care for them and keep them running a bit longer than they might otherwise.

Replacing Windshield Wiper Blades

Of course, you will have to replace your wiper blades sooner or later. The good news is that blades are fairly inexpensive auto components and installation is often pretty easy. If you have any questions or uncertainties about your vehicle’s wiper blades you can always give Aamco of Keller a call with questions regarding your car’s Windshield Wiper Blades.

While it’s important to keep your car washed and waxed to keep it clean looking, it’s also important to keep your car cleaned under the hood. Cleaning your Car’s Battery Terminals can help keep your Car Battery running better and longer. Car Battery Terminals that become overly dirty or corroded can keep your car from getting a proper charge that it needs to stay in working condition.  If you have an old battery or a mechanical failing, that’s probably going to require intervention from an automotive specialist. But if the problem is simply that the terminals on your battery need to be cleaned, that’s something you can do yourself with a few tips from our local trusted expert mechanics at Aamco of Keller.

Keep your Car’s Battery Terminals Clean

  1. First and foremost, turn off your engine. While cleaning the terminals is a simple DIY project, there is still a slight risk of injury. You can avert this risk simply by making sure you have the engine turned off while you work.
  2. Next, loosen the nut holding your negative cable in place; you’ll likely need a wrench for this. Detach the cable from the post. Then, follow the same steps with the positive cable.
  3. Take just a moment to visually inspect your car battery. Specifically look for any fissures or cracks. If you see any, that means there’s a problem with your car battery that you probably won’t be able to fix on your own; more likely than not, you’re looking at the need for a battery replacement.
  4. You’ll also want to look at the cables and clamps themselves. Again, what you’re looking for is very obvious evidence of wear and tear. If your cables or clamps have big rips or tears, you’ll probably need to have them replaced. These things really can’t be mended.
  5. Assuming you don’t see any of these obvious signs of wear and tear, you’ll want to mix your cleaning solution—one tablespoon of baking soda into one cup of water. Mix ‘em up thoroughly, then dip an old toothbrush into the mixture.
  6. Use the toothbrush to scrub away any signs of corrosion you see on your battery terminals. Don’t be afraid to really scour thoroughly to get things squeaky clean. You may have to soak your toothbrush in the baking soda mixture a couple of times as you keep scrubbing away.
  7. When you finish, use a spray bottle with cool water to rinse off any residue. It is imperative to make sure all baking soda and corrosion is washed away. Then, use an old rag or towel to pat the battery and clamps completely dry.
  8. Use a little bit of petroleum jelly to lubricate the terminals.
  9. Reattach the cables to their correct terminals.

That’s the basic guide to cleaning your battery terminals—but here’s an alternate approach: If you’re on the go and don’t have access to the above supplies, see if you can find a Coca-Cola or a Pepsi somewhere, and pour it over the terminals. Let it sit for two or three minutes, then rinse your battery clean with cool water. Note: You’ll want to follow the same basic safety steps we outlined above, including turning off your engine and detaching the cables. It’s always recommended that any car maintenance be done by a qualified expert.

The Power steering system help lower the effort needed by drivers to steer and control their cars, which is key to allowing the vehicle to maneuver without much effort and increase the driving experience. Most vehicles today use a hydraulic power steering system (HPS) to create the force necessary to move the wheels. However, manufacturers are starting to build cars using an electric power steering system (EPS). When problems arise in the hydraulic power steering system they can most often be attributed to faults in the fluid or pump, but sometimes belts or other factors are to blame.

The Aamco of Keller team are your locally trusted, expert mechanics that are here to keep you and your vehicle safely on the road. Power Steering System Damage and lack of proper power steering system maintenance can lead to more costly repairs in the future. So we always recommend having your power steering system and power steering fluid checked during your routinely scheduled vehicle maintenance.

Low Power Steering Fluid & Power Steering Leaks

A low power steering fluid level reduces the amount of hydraulic fluid pressure the pump can create. This also makes the pump work much harder, consequently wearing it out much faster. In addition, fluid is also used as a lubricant and coolant. If the components are lubricated or cooled improperly, the power steering system can be jeopardized. Failing to replace the fluid on time makes the wheel increasingly difficult to turn until it gives out altogether.

Damaged hoses and old, degraded seals are the biggest reasons for power steering leaks. An inadequate amount of fluid can cause the pump to wear out very quickly or even overheat. If this happens the pump is rendered useless and must be entirely replaced.

Broken Power Steering Belt

A belt connected to the crankshaft of the engine usually energizes the power steering pump. When belts become worn, they can slip. There’s no way you’ll miss a belt slip or snap. Broken power steering belts will reduce your steering ability as soon as it fails. This is due to the inability of the belt to power the pump.

Failing Power Steering Pump

The aforementioned symptoms also lead to the pump being worn out. After a pump is worn, the car may become even more problematic if you try to drive. As your pump ages, you’ll start to hear pump noise and the force you need to steer increases. It’s always better to get the pump fixed sooner rather than later.

Contamination of Power Steering Fluid

One of the most critical elements of the whole system is the power steering fluid. Contamination of the fluid can happen when the pumps fail, hoses deteriorate or any outside moisture enters the fluid. Such problems all result in contamination of the fluid, likely causing small openings to plug up the steering system, an increase in friction, or even interference with the fluid’s hydraulic characteristics. Contamination may lead to the failure of a power steering component.

Proper Electronic Power Steering Maintenance

The EPS system takes advantage of an electric motor, so no fluid is required! This decreases the amount of routine maintenance this system needs. However, there’s still plenty of ways to damage your EPS. For example, it’s not advised to drive over bumpy or damaged roads at high speeds. Hard bumps and vibrations can cause damage to the steering rack.

It’s also important to also check to make sure the rubber protective coverings are still in good condition. If water, dust and dirt get into the steering wheel arch, it can cause rusting and other problems for the EPS system.

Easy Ways to Maintain Your Power Steering System

Our team of ASE-certified technicians at Aamco of Keller are here to assist you with any power steering system problems while helping you avoid any more damage to your car.

Here are a few helpful reminders to help keep your Power Steering System in the best possible working condition.

Have the High and Low-Pressure Hoses Checked

Power steering fluid is transported through two main hoses. One of the hoses adds high-pressure and the other returns it back to the fluid tank with low-pressure. It’s common for leaks to form in either of the two hoses. Thus they should be checked on a regular basis to make sure that they don’t rub against one each other and that any protective coverings remain intact.

Change the Filter

Some drivers don’t even know there’s a power steering fluid filter. The filter should be changed every year unless indicated differently in the owner’s manual. It’s necessary to always keep the fluid clean so that it flows freely to reduce the wear-and-tear on the pump. It’s surprising how many contaminants make their way into the fluid’s tank. It’s the filters job to keep the contaminants out and the fluid clean.

Inspect the Power Steering Fluid Regularly

Keeping the filter changed on a regular basis in addition to keeping the fluid free from contaminants means higher quality fluid. The quality of the fluid is able to be determined from home by sampling and inspecting the color, while making sure there are no pieces of dirt, metal, grime or other pieces of debris. When the fluid is darker, the quality is a lot lower. When the fluid is dark and also has many particles and debris floating in it as well, that’s when you know it’s time for the fluid to be flushed out and replaced.

The team at AAMCO of Keller aims to educate on customers on common knowledge and potential issues they could face while on the road with their vehicle.  A lack of a proper maintenance upkeep if you fail to keep your car maintained with regular tune-ups can make small issues even bigger leading to more costly repairs. This is why we at AAMCO of Keller place the importance of proper preventative maintenance needs to our customers.  Axles are an important part of the wheel system but are a component that many vehicle owners neglect. To ensure proper vehicle maintenance, it’s good to have a basic knowledge of what the axle does and why it’s important. You should also familiarize yourself with how to tell if your axle is malfunctioning and what to do to have it repaired.

What is the purpose of your Car’s Axels?

You should first understand the axle’s role within the vehicle. All wheeled vehicles have axles. Axles are used for steering, driving, and braking, meaning they are important for basically every aspect of vehicle use. Essentially, the axles transfer power and torque from your engine to your wheels. In performing this key function, the axle must be able to sustain the entire weight of the vehicle, cargo and passengers. The axle must also withstand the accelerated forces of driving and braking.

Two Types of Axles for your Car

There are two basic types of automobile axle. The first is called the drive axle, which is connected to the driveshaft. The driveshaft is basically just a rod that extends up into the vehicle’s transmission and connects with the engine. The engine itself helps turn the axle, then.

The other type of axle is the dead axle, which is not connected to the engine at all. It turns only when the vehicle is in motion, caused by the drive axle. Dead axles are present in your vehicle to help support the weight of the car.

What happens when your Car’s Axels begin to Fail?

Since axles have to sustain such tremendous weight, they are obviously made to be robust. Even so, as with any part of the vehicle, the axles can fall into disrepair. Over time, wear and tear can weaken them and perhaps lead to the need for axle replacement.

There are a few telltale signs that your axles are in need of some work:

  • If you put your car into gear and hear a sudden clunking sound, that’s a dead giveaway that there is a problem with the axle.
  • If you encounter vibrations throughout the car, either when driving, braking, or turning, that could point to an axle issue.
  • Finally, if your car sounds like it’s running fine but it simply won’t move, that’s clearly a sign that something is awry—and more likely than not, the culprit is the axle.
  • A broken axle is a serious problem and should not be ignored, for the sake of your safety as well as the health of the vehicle. It is vital that you address a broken axle as soon as possible by taking your car to a reputable mechanic.

Can you Drive with a Broken Car Axle?

If your axles are failing it’s very ill-advised and not recommended by our team of expert mechanics at Aamco of Keller. Failing axles are at risk of breaking or completely failing at any point; when your axle fails, you’ll lose control of the car, possibly causing an accident or crashing. It’s a far better choice to have the problem diagnosed and repaired now, rather than taking that chance.  If one of your axles is truly broken or has already failed, you shouldn’t try to drive the car. It’s not safe and, chances are, you’re not going to get far if you don’t have two working axles. Which can only add to potential dangers for you and the other drivers on the road.

One of worst feelings as a car owner is to start your car and see a “Check Engine Light” come up on your dashboard. At AAMCO of Keller our team of experts are here to keep you and your vehicle safely on the road. When a Check Engine Light occurs it’s extremely important to contact your local auto repair shop to receive a diagnostic on what the issue may be for your vehicle. AAMCO of Keller provides a full diagnostic reading for FREE for our AAMCO of Keller Customers.

 

Check Engine Light On

It’s a common possibility that when you see a Check Engine Light (CEL) or heater circuit malfunction message it could mean that your O2 sensor has simply gone bad. It may also mean that your vehicle is not running properly resulting in an excessive amount of emissions. Whatever the case may be to trigger the alert, taking your vehicle into AAMCO of Keller for a full diagnostic and tune-up is the best bet to ensure that your vehicle’s O2 sensor is in top performance.

What is an Oxygen Sensor or O2 Sensor?

Today’s computerized engine control systems rely on inputs from a variety of sensors to regulate engine performance, emissions and other important functions. The sensors must provide accurate information otherwise drivability problems, increased fuel consumption and emission failures can result. One of the key sensors in this system is the oxygen sensor. It’s often referred to as the “O2” sensor because O2 is the chemical formula for oxygen (oxygen atoms always travel in pairs, never alone).

The oxygen sensor, also known as a lambda sensor, was developed in the late 1960s by Dr. Gunter Bauman for the Robert Bosch GmbH company. This sensor is an electronic device used to measure the proportional amount of oxygen in a liquid or gas. The original oxygen sensor was made using ceramic coated zirconia and platinum.  The first O2 sensor was introduced in 1976 on a Volvo 240. California vehicles got them next in 1980 when California’s emission rules required lower emissions. Federal emission laws made O2 sensors virtually mandatory on all cars and light trucks built since 1981. And now that OBD-II regulations are here (1996 and newer vehicles), many vehicles are now equipped with multiple O2 sensors. In order to make the O2 sensor more capable of mass production, planar oxygen sensors were developed. This modernized O2 sensor was developed by NTK in 1990 for use in the Honda Accord and Honda Civic car models. Made using layers of High-Temperature Cofired Ceramic (HTCC) green tapes, the current style of the sensor is made more efficient than the original style sensors.

What is the function of an Oxygen Senor for your car?

Cars that were manufactured post-1980 feature an oxygen sensor. It is located within the emissions control system. When functioning, the O2 sensor sends data to the management computer located within the engine. In your car, a functioning O2 sensor ensures that your engine is running at top performance. Additionally, this sensor keeps your emissions in check and alerts you to when emissions are too excessive. For states that have vehicle inspection programs to regulate emissions, the use of the CEL and O2 light will alert officials to any excessive emissions. As a result, if one or more of your oxygen sensors is faulty during an emissions inspection for your car, you will most likely not pass the inspection.

The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine. Monitoring oxygen levels in the exhaust is a way of gauging the fuel mixture. It tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen).  A lot of factors can affect the relative richness or leanness of the fuel mixture, including air temperature, engine coolant temperature, barometric pressure, throttle position, air flow and engine load. There are other sensors to monitor these factors, too, but the O2 sensor is the master monitor for what’s happening with the fuel mixture. Consequently, any problems with the O2 sensor can throw the whole system out of whack.

Are there multiple Oxygen Sensors in a Car?

Cars with O2 sensors have a minimum of one sensor in front of the catalytic converter, as well as one in each of the car’s exhaust manifold. The actual number of oxygen sensors for a car depends on the year, make, model and engine. However, most of the later model vehicles have four oxygen sensors.

 The number of sensors varies according to engine type:

  • V6 and V8 transverse have four oxygen sensors including a left or front bank upstream; right or rear bank upstream; rear of the engine; and a downstream sensor
  • 4 and 6 cylinders in-line have three oxygen sensors including a front and rear bank upstream and a downstream sensor
  • Traditional V6 and V8 have three oxygen sensors including a left bank and right bank sensor upstream and a downstream O2 sensor
  • 4 cylinder transverse has an upstream and a downstream O2 sensor

What are Oxygen Sensors Doing for Your Engine?

When a gasoline-powered engine burns gasoline there is oxygen present. Oxygen in an engine is the result of a number of factors including the air temperature, altitude, engine temperature, load on the engine, and barometric pressure. The ideal ratio for oxygen and gasoline is 14.7:1, which slightly varies depending on different types of gas. In the instance that there is less oxygen present fuel will remain after combustion, which is referred to as a rich mixture. On the other hand, if there is more oxygen present it is referred to as a lean mixture. Both the rich and lean mixtures are bad for your car, as well as for the environment. A rich mixture results in a fuel that is not burned that creates pollution. A lean mixture generates nitrogen-oxide pollutants, which can lead to decreased vehicle performance and engine damage. Oxygen sensors are positioned near points in the exhaust system so to determine if there are rich or lean mixtures in your car.

Typically, an O2 sensor creates a voltage due to a chemical reaction resulting from an off-balanced gasoline to oxygen ratio. Most car engines can determine how much fuel to expend into the engine based on the voltage of the O2 sensor. If your oxygen sensor fails to function properly, your engine management computer cannot determine the air to fuel ratio. Therefore, the engine is forced to guess how much gasoline to use, resulting in a polluted engine and a poorly functioning vehicle.

How do you test if your Oxygen Sensor is working properly?

There are two common ways to test your Oxygen Sensor which can include leaving it attached to your car or taking it off the vehicle. For an experienced mechanic it will require two main testing tools which include a high-impedance digital voltmeter and a backprobe. The first step to checking an O2 sensor is to locate the surrounding wires to make sure they are intact and without visible signs of wear and tear. Next, the vehicle must be started and allowed to run until the engine reaches 600 degrees F so to ensure an accurate reading of the sensor. Using the back probe and voltmeter, the oxygen sensor is measured at a set number of points and under particular conditions to determine any faulty measurements.

Testing the Oxygen sensor of your car generally requires a specialized amount of training and we highly recommend that you have an expert mechanic handle the testing of your cars Oxygen Sensor.  At AAMCO of Keller we aim to be your local trusted auto repair experts.

So you’re leaving work and you realize you left your car lights on all day and now your vehicle won’t start.  As a well prepared motorist we always suggest that you keep a reliable pair of jumper cables in your car for situations just like this. Having the right emergency equipment is the first important step. You also have to know how to use it. So, here is what you need to know about how to jump a car battery.

Being prepared with the right Jumper Cables

Jumper cables are long, thickly insulated cables with toothy clips on one or both ends. These clips are called alligator clips (because they look like alligator heads). The clips are distinguished by color, usually red and black, to indicate positive and negative polarity. The red clip is positive. The black clip is negative.

Jump boxes are portable batteries used to jump start a vehicle without connecting to another vehicle—come with special jump cables. These cables connect the jump battery directly to the dead car battery. Road side assistance usually uses a jump box when helping stalled vehicles.

Jumper cables are the most popular tool used to jump start cars because they are inexpensive and easy to store. Jumper cables usually come in a variety of lengths, ranging from 10-20 feet. Some people think longer cables are better so that you do not have to move a car with a dead battery. But, while longer cables provide convenience, they may lose power as the longer the cable, the farther the energy has to travel. The gauge of the cable denotes the strength of the cables. The lower the gauge, the thicker the cables and the stronger they are. Gauge six is a standard size for jumper cables.

Safety First When You Jump a Car Battery

You should consider all safety risks before performing any basic maintenance or repair on your car. First, make sure that small children are in a safe area away from the engine while you are establishing how to jump a dead car battery. Take a moment to read the manual of your car. Some vehicles require extra steps in order to have a successful jump. If you’re unsure of what to do, call AAMCO of Keller at (817) 431-0009 for advice. Assuming that your car will permit a jump, you should be careful to prevent dangerous electric shocks. When you handle the jumper cables, be aware that their function is to transmit electrical current from one car to another. Once one end of the jumper cables is connected to a car, do not touch the metal clamps to anything but the appropriate target. It’s highly recommended that you wear the proper safety protection gear such as safety classes to avoid possible sparks flying.

How to Jump a Car Battery

Step 1:  To ensure that the car donating a charge (the donor car) is protected, take these precautions. Match the kind of voltage system of the donor battery to the dead battery to be jumped. For example, a 6V and a 12V should not be used together. A quick test that there is enough voltage for the donor, be sure that the car giving he jump start’s headlights are steady and bright when the car is started. If the headlights dim, that can signal that the battery is low.

Step 2:  Park the vehicles next to each other. Park the functioning car so that the vehicles face each other, preferably only about 18 inches apart, but never touching each other. For automatic transmission cars, put the vehicle in park; for a manual transmission, set the vehicle to neutral. Set the parking brakes on both, so neither car moves unexpectedly.

Step 3:  Both vehicles should be off. Set the parking brakes and remove the keys. Set down the jumper cables on the ground, making sure the clamps do not touch each other.

Step 4:  Open the hood to both cars, and locate the batteries (refer to the owner’s manual for battery location) and battery terminals. Usually, the two terminals on each battery will be covered in red or black, with a + or – sign on top. Look at the batteries and make sure that you can identify which is positive, and which is negative. This distinction is crucial to the success of your jump. If the battery terminals are dirty, wipe them off with a rag or wire brush.

Step 5:  Attach the red, positive cable clamp to the positive (+) battery terminal of the dead battery. You want a solid connection to the battery terminal, which may require some initial wiggling of the clamps

Step 6:  Attach the other red clamp to the positive terminal on the working battery. Attach the red, positive cable clamp on the other side of the jumper cables to the functioning vehicle’s positive (+) battery terminal.

Step 7:  Attach the partnered black clamp to the negative terminal on the working battery. Connect the black, negative cable clamp to the working battery’s negative (-) battery terminal.

Step 8:  Walk over to the car with the dead battery. Do not connect the black, negative cable clamp to the dead battery. Instead, attach that clamp to an unpainted, metal part of the car such as a shiny, clean nut on the engine block. This will help ensure a safe jump.

Step 9:  Start the working vehicle. Wait a minute or so. Depending on the age of the battery and how long since it died, you may need to let the car run for a minute or two to get the jump to work.

Step 10:  Try starting the dead car. If the car doesn’t start, allow the working vehicle to charge the battery for an additional minute or two before attempting again.

Step 11:  If it doesn’t turn on, try revving the engine of the working vehicle. In some instances, slightly revving the engine of the working car while charging the dead battery may help.

Step 12:  Once the dead car is running, you may disconnect the jumper cables, starting with the black, negative cable clamps. Do not let the clamps touch each other while any part of the cables is still attached to a car.

Take a short drive to help recharge the battery.  This will allow the battery to build up a charge. This driving allows the vehicle’s alternator to charge the battery and ensures that your vehicle does not die again once you turn it off.

The vehicle with the dead battery should be allowed to run for 30 minutes if possible. This will let the alternator fully charge the battery. If your battery continues to lose a charge call AAMCO of Keller to perform a diagnostic test on your car battery.

What If Your Jump Start Doesn’t Work?

If the jump fails to start your car after a few short attempts, or if the car starts but then dies again, you have some other issues you need to address. Most batteries are rated to last 4-6 years. If your battery is old, you may need to replace it. If the battery should be working well, you should consider other possible problems with other components

Dealing with a dead car battery is a pain. Luckily, getting your car working again is not terribly difficult. By following these instructions, using your jumper cables sensibly, practicing safety and addressing other potential concerns, your car will run better, be safer, and last longer.

If you have questions about jumping your car or your vehicle won’t respond to a jump start give the experts at AAMCO of Keller a call at (817) 431-0009 to answer your questions or to schedule an appointment for a full diagnostic test.

Summer is quickly approaching the Dallas/Fort Worth area and the summer heat is no joke for your car. Keeping your cars radiators and cooling system in proper working order is super important to ensure you’re not left stranded in the Texas Heat with a car that’s overheating.  At AAMCO of Keller we aim to be your locally trusted auto repair experts to help keep you and your family on the road safely this summer.  Here is some important info to learn about your car radiator and cooling system.

The car radiator is one of the most misunderstood automotive components. This may be because a car radiator works so differently from a home radiator. The one in your home works essentially to warm up the immediate surroundings—but the one in your car does something a little different.

The Car Engine Cooling System

It’s actually an invaluable part of your engine cooling system. Of course, your engine both burns fuel and creates friction in order to give your car the juice it needs, and that causes a great deal of heat to build up. That heat needs to be diverted away from the engine, or else it could cause tremendous damage. The pistons in the engine would seize up and snap in two, and the engine would be broken down completely. That’s why engines have built-in, multi-part cooling systems. This includes an exhaust system, through which heat can escape. It also includes oil, which lubricates the engine parts and reduces the amount of friction. Even so, engines can get hot pretty quickly—and once they hit a certain temperature, the rest of the cooling system kicks in.

A typical 4 cylinder vehicle cruising along the highway at around 50 miles per hour,  will produce 4000 controlled explosions per minute inside the engine as the spark plugs ignite the fuel in each cylinder to propel the vehicle down the road.  Obviously, these explosions produce an enormous amount of heat and, if not controlled, will destroy an engine in a matter of minutes.  Controlling these high temperatures is the job of the cooling system. The modern cooling system has not changed much from the cooling systems in the model T back in the ’20s.  Oh sure, it has become infinitely more reliable and efficient at doing its job, but the basic cooling system still consists of liquid coolant being circulated through the engine, then out to the radiator to be cooled by the air stream coming through the front grill of the vehicle. Today’s cooling system must maintain the engine at a constant temperature whether the outside air temperature is 110 degrees Fahrenheit or 10 below zero.  If the engine temperature is too low, fuel economy will suffer and emissions will rise.  If the temperature is allowed to get too hot for too long, the engine will self-destruct from overheating.

What Happens When Your Car Radiator Kicks In

There are actually two types of cooling systems found on motor vehicles:  Liquid cooled and Air cooled.  Air cooled engines are found on a few older cars, like the original Volkswagen Beetle, the Chevrolet Corvair and a few others.  Many modern motorcycles still use air cooling, but for the most part, automobiles and trucks use liquid cooled systems and that is what this article will concentrate on.

The cooling system is made up of the passages inside the engine block and heads, a  water pump to circulate the coolant, a thermostat to control the temperature of the coolant, a radiator to cool the coolant, a radiator cap to control the pressure in the system, and some plumbing consisting of interconnecting hoses to transfer the coolant from the engine to radiator and also to the car’s heater system where hot coolant is used to warm up the vehicle’s interior on a cold day.

A cooling system works by sending a liquid coolant through passages in the engine block and heads.  As the coolant flows through these passages, it picks up heat from the engine.  The heated fluid then makes its way through a rubber hose to the radiator in the front of the car.  As it flows through the thin tubes in the radiator, the hot liquid is cooled by the air stream entering the engine compartment from the grill in front of the car.  Once the fluid is cooled, it returns to the engine to absorb more heat.  The water pump has the job of keeping the fluid moving through this system of plumbing and hidden passages.

How the Car Radiator Works

  • A thermostat at the front of the engine detects when the engine reaches an unacceptable temperature. This triggers the release of water and coolant—both of which are held in the radiator.
  • This liquid combination picks up the heat generated by engine friction and burned fuel. It is then sent back into the radiator itself. The surface area is ample enough to let the coolant cool. Additionally, a fan positioned near it helps cool the coolant further.
  • Air from outside the car is brought in through vents, providing further cooling power. The coolant sufficiently cooled down, can then be sent back into the engine to pick up more heat.

What Happens When a Car Radiator Cooling System Stops Working Properly

The long and short of it is that your radiator plays a vital role in removing heat from your engine—thereby ensuring the engine can function properly, without risk of sudden breakdown. Over time, of course, various issues can prevent the cooling system from working properly. One common issue is that the thermostat, from which the coolant is released into the engine, becomes clogged and no longer opens. This is a significant problem: It means the engine can overheat and ultimately break down if you don’t have the problem corrected right away. An even more common reason for cooling system breakdown is a leak; leaks can cause coolant levels to become too low, which means there is not enough coolant to pick up the heat and remove it properly.

Certainly, if you notice fluid under your parked car and suspect a leak, it’s important to have the vehicle inspected and serviced right away. These problems can be serious, but spotting them quickly can lead to a more straightforward solution.

Is Your Car Radiator In Need of a Radiator Flush?

Anti-freeze, otherwise known as coolant, is the engine’s temperature-regulator. If you’ve ever had your engine overheat, you know how important it is to have the right amount of coolant. Think of your engine as producing a series of tiny explosions. The coolant is the fluid that keeps those explosions burning at the right temperature. The coolant keeps the engine warm in a brutal winter and cool during a blazing summer.

At AAMCO of Keller we recommend as a general guideline to flush the car radiator anti-freeze once a year. This removes any rust or scale deposits and keeps coolant from becoming acidic. Acidic anti-freeze eventually wears down the very parts the cooling system intends to protect.

What are the Benefits of a Car Radiator Coolant Flush?

  • Old anti-freeze eventually loses its anti-corrosive properties, which allows for debris to build up in the cooling system. A coolant flush removes these rust and scale deposits. It’s important to get rid of contaminants because they can cause overheating and damage your entire cooling system.
  • Fresh coolant contains additives which lubricate and can extend the life of your cooling system. These additives also help prevent rust from building up, which allows the cooling system to operate more efficiently.
  • Bring your car into AAMCO of Keller Automotive for a coolant flush and we’ll offer a free courtesy inspection. During this comprehensive evaluation, we check the entire cooling system – including the thermostat, radiator, water pump, hoses and belts.
  • A coolant flush prevents the old anti-freeze from becoming acidic. Once coolant becomes acidic, it starts to eat away at the water pump, rubber hoses and aluminum components of the engine.

Overheating is one of the most common contributors to mechanical breakdowns for many car owners in the North Texas area. Overheating can cause severe damage to the engine and transmission.
