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

You may be fanatical about keeping the outside of your vehicle clean.  But what about what's under the hood? Have you ever thought about how dirt and grime may be affecting your engine's components? One of the most important parts under your hood to keep clean is your vehicle's battery.  With a daily barrage of dirt and moisture, outside parts of your battery can corrode, namely the cables and terminals. Gases vented by batteries can also promote corrosion.  That can create connection problems and affect your vehicle's electrical system.  If corrosion is not cleaned off, it may damage wires and terminals so badly that they will stop properly conducting electricity.  At that point, they may need replacing. When you bring your vehicle to us for a battery inspection and cleaning, we will remove any corrosion and put corrosion-resistant protection on each post. A technician will also visually inspect your battery.  Plus, we can test how much life is in your ba ... read more

If your vehicle isn't starting or doesn't sound like it used to when you crank it, the culprit may be the battery.  You may have left a light on, or something plugged into one of charging ports.  Maybe you accidentally left your vehicle in the "on" or "accessory" position when you last got out. Maybe you've left it in the garage or driveway for a long time without starting it.  That can spell the end for a vehicle battery. It's also possible that your battery is just simply too old. There's no standard lifespan of a battery, but 3-5 years is about average, even though some people only get 2 and heavier duty batteries may last many more. It's possible your battery is defective, too.  And it could be your vehicle's charging system isn't recharging the battery.  Whatever the cause, if you're having problems with your battery, it's a good idea to bring it in and have us perform a thorough battery test.  With state-of-the-art testing equipment, a technician wil ... read more

If you notice your brakes aren’t working like they used to, that’s the kind of thing that’s important to have checked out soon.  That’s because your brakes are extraordinarily important to the safe operation of your vehicle.  Sometimes you feel like your brake pedal is feeling a little soft or it’s lower than usual. Or you might feel like the brakes are on all the time, holding you back. Maybe when you release the brake pedal, it comes back up more slowly than usual. There are a few different problems that can cause your brakes to feel like any of those things, so bring your vehicle in to us and we can inspect them. One possible cause of those brake issues is a damaged or worn-out brake hose.  Your hydraulic brakes work by carrying brake fluid to each of your wheels.  There are steel lines that carry the fluid most of the way, but because your wheels are moving all the time, a flexible hose is used to connect the steel lines and the bra ... read more

When the temperatures plunge, your vehicle better be ready because it faces a whole new set of challenges.  Rubber stiffens, glass fogs, fluids freeze.  Just thinking about it can get your heart beating faster.  So here are some tips for getting ready for those inevitable colder temperatures. Make sure your tires are in good shape and properly inflated.  Traction can be less than ideal on slippery streets, so your tires must have enough tread to grip the road.  They should also be inflated properly, and inflation will change as the temperatures go down. One last thing on tires. Do you know how old yours are? They actually have a birthdate printed on them.  Old rubber can compromise drivability and handling.  Some tires look great but their rubber doesn't handle stresses like it used to.  Have your vehicle service facility inspect all of these aspects of your tires so you are riding on tires that are fit to go. Anyone who lives in an area where th ... 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

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the "good old days."  Today, we take our steering for granted: until something goes wrong, that is. Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches.  Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid. Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for: A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn. Signs of hydraulic fluid leaking, such as wet spots under your vehicle. The smell ... read more

When the weather turns cold, it's nice to crank up the furnace and enjoy the heat. But if your home's furnace doesn't work, it's not too comfortable. Same goes with your vehicle. When the heater's not working, things can get miserable. It could also signal some major problems, which we'll discuss later. A vehicle's heating system is fairly complicated. It's made up of several parts, including a blower motor/fan, a heater core and some mechanical and electrical components. In basic terms, a vehicle's engine warms up coolant which is then sent to the heater core (which is kind of like a small radiator) behind the dash. That blower motor sends cold air through the heater core which heats up the air. Voila! Heat. Diagnosing problems in this system takes a trained mechanic because of the different possible issues. Your heater core may need replacing; they are sometimes in tight spots and may be difficult to work on. Another possible problem could be a defective thermostat, which regulates h ... read more

After months of postponing travel far away from home, a lot of us can't wait to hit the road and scream "Road Trip!" again.  But how long has it been since the vehicle you're planning on taking has had a thorough inspection? And is it roadworthy for several days on the highway? Time to schedule a professional trip inspection in our service center.  When it comes to long trips, before you go, make sure you can stop.  We can perform a break inspection.  Our technician will visually inspect your brakes for wear and how much life is left in the brake pads and rotors.  They'll also check your brake lines and fluids for fitness and fill. If it's going to be a long trip, it's important that your engine stays lubricated.  The technician will see when the last time you had an oil change, check the levels and inspect the system for leaks.  If you are close to needing an oil change, it's best to have it done before the trip because no one wants to interrupt a va ... 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
