It’s just common sense that your vehicle will drive better if all the wheels are lined up with each other and the road the way the engineers intended.  When they’re not, that is called being out of alignment.   Here are some signs that your alignment has problems. Your steering wheel isn’t straight when your vehicle goes straight down a straight road. This one’s pretty easy to notice.  If your vehicle’s logo on the wheel is tilted, that’s probably not the way designers wanted it to be. Bring it in and have us check it out. Your steering wheel is vibrating on a smooth road or when you are accelerating.  While this could be caused by several different things, one possibility is misalignment.  If your steering wheel is shaking, it should be examined by a trained technician. Your vehicle is pulling to one side without you wanting it to.  Sometimes the configuration of the road will cause it to pull slightly left or rig ... read more

Most of us know a bad muffler when we hear it.  That loud, rumbling sound is unmistakable. Did you also know you can get a ticket for driving around with a loud exhaust system? If your exhaust system has a leak in it, it may be allowing poisonous gases inside your vehicle and could make you seriously ill (or even kill you!) if you breathe too much in. Unfortunately, your exhaust system faces a lot of destructive forces out on the road.  Rust is the worst, and not just in colder climates where they use salt and brine as de-icers.  Exhaust systems can rust from the inside out when moisture condenses inside the pipes.  Vibrations and jolts from rough roads (and the occasional run in with a rock or a curb) can wreak havoc with exhaust systems.  Even a bad oxygen sensor can send too much fuel into the catalytic converter, and the resulting heat can wind up destroying this very expensive component. Your exhaust system is made up of several parts, and all need to be i ... 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

Did you know that having a burned out headlight can result in your rearview mirror reflecting some flashing lights? In other words, you might get pulled over by the police for only having one working headlight, because in most places it's against the law.  Not only is it illegal to drive with one headlight burned out, but it's also dangerous. You can't see down the road nearly as well at night with only one headlight, and other drivers can't see you as easily either. The good news is many newer vehicles warn you when one of your headlamps burns out. When that happens, have it taken care of as soon as you can.  While there was a time when all headlamps were pretty much the same, the same isn't true these days. There are halogen, Xenon, LED and other technologies used in modern vehicles.  Plus there are sealed beams (like those on older vehicles) and capsules. If you have a burned out headlamp, ask your service advisor for recommendations.  Usually when one side goes ... read more

You may have heard the old saying, "My get-up-and-go got up and went." If your vehicle's engine's fuel economy is noticeably worse, your engine is idling roughly or stalling or your vehicle's acceleration isn't what it used to be, ask your service advisor if you might need your vehicle's fuel and air induction systems cleaned. As the hours pile up on your engine, carbon deposits can build up.  It's not unusual for some of the impurities and additives in fuel to leave behind a black residue that eventually will negatively affect your fuel economy and performance. Maybe you're noticing your engine is harder to start, you hear knocking or pinging in your engine and your vehicle just doesn't have the pep it used to. While it's a sophisticated process with a lot of components, a gasoline engine essentially produces power by drawing in air from the outside and mixing it with fuel in the cylinders where this blend of fuel and air is ignited by spark plugs in synchronized explosions. The ... read more

When you head down a straight road, does your vehicle pull to one side?  Do you feel vibration in any of the wheels? If you've noticed any of these things, it's probably time for you to get your wheel alignment checked. When your vehicle left the factory, its wheels were parallel to each other and perpendicular to the ground.  That maximizes traction for good steering and braking. Every time you take your vehicle on the road, normal wear and tear will affect your alignment. Hit a bump, a pothole or a curb and all those little knocks will add up Bad alignment not only can cause your steering wheel to pull unevenly, it can also wear your tires out a lot faster than they should. In fact, if you look at your tires and see one side of the tread is a lot smoother than the other, it could be another sign of bad alignment. Since different problems can cause similar symptoms, the first thing our trained technician will do is test drive your vehicle. Then, they'll check the front end a ... read more

Ever wonder how all-wheel-drive or 4-wheel-drive vehicles get the power from the engine to the front and rear wheels? The magic happens in what's called a transfer case.  In some all-wheel-drive vehicles, it's sometime called a power take-off unit, or PTU. Inside the transfer case is a set of gears.  And to keep those gears meshing smoothly, they have to be lubricated and kept cool.  What does that is called transfer case fluid. Depending on your vehicle's type of transfer case, it is filled with either an automatic transmission fluid, a gear oil that's a bit thicker or transfer case fluid designed to be use for your transfer case. As happens with all lubricating fluids, the transfer case fluid has things in it that break down the older they get.  They have corrosion inhibitors, detergents and anti-foaming agents that keep the lubricant from getting air bubbles in it. Transfer cases don't have filters in them to clean out impurities. If you don't have your transfer ... read more

No matter what the weather is like outside, your internal combustion engine expects to keep its cool all the time, even when it's really cold.  That's because engines create the power that moves you to your destination by a series of tiny explosions of a fuel and air mixture. In turn, that generates a lot of heat in a small space. Your vehicle has a complete cooling system with a lot of different parts that work together to keep the temperature at a point where the metal engine parts won't heat up enough to warp.  Its lifeblood is coolant, a liquid that circulates through the engine (and, in most vehicles, the transmission, too) through a series of hoses and tubes.  In order to get rid of the coolant's heat, your vehicle has a part you probably recognize: the radiator.  It does what its name proclaims: radiates heat.  The radiator has a series of thin metal fins that coolant goes through, and when outside air passes over them, the heat is dissipated from the ra ... read more

Brakes are one of your vehicle's most important safety components, and you may have noticed that they don't stop as surely as they used to.  Maybe it takes you applying a little more pressure to them than before, or perhaps you get the feeling that they're not stopping you as quickly. Those could be signs that your brake fluid needs changing.  Hydraulic brake systems use a fluid that enables the brakes to apply their stopping power to the wheels.  That fluid can wear out, degrade, become contaminated or pick up air and moisture.  All those can eventually contribute to brakes that feel sluggish. Driving with old, worn-out brake fluid may also shorten the lifespan of other braking components. Our technicians can evaluate your brake fluid to see if it needs changing. Your vehicle's manufacturer recommends how often that should be done, and when it needs changing may depend on how and where you drive. Our technicians can check the condition of your brake fluid when you ... read more

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated.  If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident. All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS.  One system uses small sensors in the tires that continually check the pressure in each tire.  That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire.  Another system works with your antilock brake system to measure the size of your vehicle’s tires.  When one wheel is going faster than another, it will spin faster. A computer sees that and alerts ... read more
