Read a Good Tire Lately? (Tire Wear)

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

Go With the Flow (MAF Sensor Replacement)

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

I'm Cool With That (AC Exchange)

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

Not-So-Smooth Operator (Transmission Signs of Trouble)

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

Oh, Stop! (Disc Brake Service)

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

Straight to the Point (Alignment Signs of Problems)

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
