There's a belt that snakes through your engine. It's even named for a snake, the serpentine belt. It'll bite you when it breaks, possibly leaving you stranded. So, it's good to know a little about this snake-like belt. In early engines, there were lots of belts. They were used to convert the rotating power of the engine to turn a mechanical part. But engineers had an idea. Why not consolidate all those belts into one that ran a bunch of different parts simultaneously? Voila! The serpentine belt. It's found in the front or side of your engine unlike older belts which were often in a V shape, the serpentine belt has ribs on it which more effectively connect with the pulleys that power the other components. A serpentine belt may power the water pump, power steering pump, alternator, and the air conditioning: all from one crankshaft. Now, all that's fine when everything is working well and the belt is intact. But when a serpentine belt ... read more

In a perfect world, all wheels and tires would be perfectly round and weigh exactly the same at every point of the wheel. Unfortunately, they're not, and if they're out of balance, they can reduce the lifespan of your tires, make your vehicle shake like a carnival ride, and maybe even damage a few suspension parts along the way. You don't want that! Wheel balancing, sometimes known as tire balancing, is a process by which a technician makes sure your tire/wheel assembly has evenly distributed weight. If it isn't, it can give your ride bad vibrations. If you feel your vehicle's steering wheel shaking, it can mean unbalanced wheels in the front. If you can feel a vibration in your seats, it could be unbalanced rear wheels. In addition to your vehicle vibrating at higher speeds, there are other signs that your wheels are out of balance. You may see uneven tread wear, or you may notice you aren't getting the kind of fuel economy you used to. When you experienc ... read more

With hotter weather and brutal heat waves becoming more common, the pressure in your vehicle's tires goes up. After all, heat causes air to expand, and the air in your tires follows the laws of physics. Overinflated tires can reduce your vehicle's traction, cause a hard, punishing ride and make your tires wear out faster; all are important safety issues. Four out of every ten drivers rarely check tire pressure. Some rely on their vehicle's tire pressure monitoring system (TPMS) to keep an eye on proper tire inflation. But it's not designed to do that. TPMS is a safety feature that has been required on vehicles made in 2008 or later, using sensors in the wheels that alert you to tire pressure problems. That warning can be a light on your dash, a digital message or a readout of the pressure in each individual wheel. But a study showed that more than 40 percent of drivers don't even know what the tire pressure monitoring light symbol looks like! One looks like a ho ... read more

If you drive a vehicle with a gasoline engine, thank the spark plugs for igniting the gasoline/air mixture in each cylinder that keeps your vehicle traveling smoothly down the road every day. Your spark plugs work hard, firing thousands of times in a well-choreographed order, and you usually don't pay much attention to them until one of them stops working the way it should. Signs that spark plugs are wearing out include: Engine runs more roughly than it did Vehicle doesn't start as easily as it used to Vehicle hesitates when you press on the accelerator Your fuel economy has gotten worse When a spark plug stops working altogether, you will find your engine has likely lost a lot of its power and isn't running smoothly. Your Check Engine light may come on. Then it's time to head to come to our service center to have it diagnosed. If your plugs need to be replaced, they're usually done all at the same time. And if your vehicle has spark plug wires, experts recomm ... read more

For drivers, S stands for safety. And there are three other words that start with S that are all equally important: starting, stopping and steering. For your vehicle to be at its safest, all three functions must be in top shape. Steering is one of those things we take for granted. After all, you turn the wheel and your vehicle changes direction. But sometimes you might notice your steering is a little off. Maybe you've noticed you turn your wheel slightly and your vehicle doesn't turn. You may feel a little vibration in the wheel that increases when you go faster. You may hear a little squeak from the wheels when you steer and you may notice your tires aren't wearing evenly. These are signs that your tie rod ends may be failing. Tie rod ends help connect your vehicle's steering mechanism to the wheels. They can wear out after you've hit one too many potholes or just from constant use. They can cause sloppy steering and loose handling, and they ... read more

There's lots of good information to read in books and online. You might not know that you can also "read" your tires and learn a lot about what shape they're in and if they are in need of attention. It's important to know how your tires are doing because a tire failure can be very dangerous to you, your passengers and others on the road near you. You read your tire by looking at the surface that rides on the road, where the tread is. Check out the outer and inner edges. If you notice there's more wear on the inner or outer edge than on the rest of the tread, your vehicle could be out of alignment. Wear on an inner or outer edge could mean your wheels are leaning too much to one side. When you see this, visit our service center soon to have the alignment checked. What about if both edges are worn? That could be a sign that you don't have enough air in that tire. In an underinflated tire, the middle is not contacting the road surface as much as the edg ... read more

A driver brought her vehicle into the shop the other day and told us how she was getting lousy fuel economy and that the engine was running rough. Plus, the Check Engine light was on. Our technician checked the code the engine had generated (why the Check Engine light was on) and found the problem. It was a faulty Mass Air Flow sensor, MAF sensor for short. This MAF sensor is an important part of your vehicle. What it does is calculate the amount of air going into your engine. As you may know, air is taken into your engine where it's mixed with fuel. Then, the spark plugs fire, that explosive fuel/air mixture detonates, and all these sequential explosions together provide the power to get your vehicle moving down the road. It makes sense that if the MAF sensor isn't sending the engine's computers the correct information on the amount of air going in the engine, the fuel/air mixture isn't going to be right. It will either too rich (too much gaso ... read more

On a hot day, you want your vehicle's air conditioning to work. When the air blowing out of your vents isn't cold, it's easy to think, "I'll just take it by the shop and have them top off my refrigerant." But while some people think air conditioning is that simple, it's actually not. If your refrigerant is low, something has to have happened for it to be depleted. Perhaps there's a leak in the system. Or some hoses or clamps have failed. If the system isn't evaluated by someone who knows air conditioning, it's possible that adding refrigerant will just be a band-aid solution. It's also possible that contaminants have gotten into the refrigerant, such as carbon dioxide, nitrogen, argon, or air. Some of those gases do not condense like refrigerant does which can increase the pressure inside the system and strain the lines and other components. At that point, the best course of action may be to have the old refrigerant (with its contaminants) bled from the sy ... read more

You are heading down a flat, newly paved street when all of a sudden you feel it. Your vehicle jumps a little bit when you're accelerating and changing gears. You know it's not the surface of the road because it's smooth as silk. So what did you just feel? That kind of jumping—or grinding or slipping—during gear changes could be a sign of trouble in your automatic transmission. And it's important to get it checked out fairly soon because some transmission problems that aren't fixed early can lead to more involved and expensive repairs. By far most vehicles on the road in North America have automatic transmissions, and they are workhorses. Unlike early cars with balky, hard-to-shift manual transmissions, the latest automatics allow you to drive without having to even think about gear changes. But you should know about a few signs of trouble to look for if they ever start showing up. When you first get going and shift your vehicle from Par ... read more

Every time you drive your vehicle, you wear down your brakes just a little bit. And after a while, that adds up. Gradually, your stopping power isn't like it used to be. Since brakes are one of your vehicle's most important safety features, it just makes sense to keep them performing well. Most vehicles have disc brakes. One key component, as the name suggests, is the disc. Most vehicles have discs on their front and rear wheels. The discs (also called rotors) are made of metal, and each rotates with the wheel hub. Your brakes also have pads that make contact with the rotors when you press down on the brake pedal, and the friction stops your vehicle. After many, many stops, that friction wears down both the pads and the discs and reduces their ability to stop the way you need them to. The discs may also become uneven from all the heat they generate, and your brakes won't stop as well as they used to when they were newer. Some signs ... read more
