There's something you can do that helps your tires last longer, wear more evenly and your vehicle handle better.  "Sign me up," you say! Wondering what that is? It's aligning your wheels, and it will literally point you in the right direction when it comes to a better and safer driving experience. When your vehicle was designed, the engineers made sure your tires were all pointing the same way by designing the suspension to make optimal contact with the road. That way the ride is smooth, you don't feel vibrations or shimmying and your vehicle travels in a straight line, without pulling to one side or the other. Unfortunately, your vehicle is not brand new; time and distance take their toll.  After hitting countless bumps, potholes, or the occasional curb, your suspension gets knocked a little out of kilter.  Those precise angles the engineers planned on for your vehicle? They get out of whack Uneven or premature tire wear is one of the first signs your alignment may be o ... read more

Ever wonder how your vehicle is able to move over bumps, potholes and other irregularities in the road and you hardly feel a vibration in the cabin? It’s your shocks and struts doing the hard work along with the rest of your suspension and tires.  They keep the ride smooth and are important for your vehicle’s safe operation.  So, how do you know when your shocks and struts are wearing out? One way is to look at the surface of your tire (where the rubber meets the road—where the tread is).  You might see some little indentations in certain spots, known as tire cupping.  If your vehicle takes longer to stop than it used to, takes a dive when you hit the brake pedal or bottoms out (scrapes) on a big bump in the road, that’s another sign, as are loud, odd noises. You may also notice your vehicle sways more than it used to. Every once in a while, look around at your shocks to see what shape things are in.  If you see the rubber cover cracked ... read more

When you are pointing your vehicle straight down the street, it should go straight.  That’s pretty straightforward, right? Sometimes, though, you may notice you have to keep adjusting the steering wheel to keep going straight.  While that could be caused by many different issues, one possibility is that you have a failing or bent control arm. Another sign is that when you brake, your vehicle pulls to one side or the other.  Sometimes your suspension may sound noisy, especially when you’re traveling on rough surfaces.  A damaged control arm may also make it almost impossible for you to get a good wheel alignment.  The control arms are part of your suspension, and some vehicles have upper control arms and lower control arms.  Not all have the same number of control arms, but one thing is important: If you have worn bushings on your control arms or a worn-out ball joint, the control arm on the other side should also be replaced.  The rubber b ... read more

Steering a vehicle these days doesn't take much effort, but if you got behind the wheel back before power steering was invented, you'd need to practically have the strength of Hercules to turn the wheel.    The first power steering systems widely available changed everything.  Chrysler introduced its Hydraguide power system in 1951. The "hydra" was for a hydraulic pump. It pressurized fluid that multiplied the force applied to the steering wheel so it was easier to turn the wheels on the ground. That pump got power from a belt attached to the engine, but unfortunately it wasted a lot of energy in the process. Plus, the system of hoses and pumps required a fair amount of maintenance and repair. Some say this system provides the most "natural" steering experience of power systems. Recently, automakers have turned to electric power steering.  It gets its power from the car's electrical battery and charging system and uses an electric motor to turn the wheels.  Sin ... read more

No, ERG isn’t the sound a pirate makes.  It’s a part in your vehicle that recirculates exhaust gas to reduce certain gases and pollutants in the atmosphere.  In fact, ERG stands for “Exhaust Gas Recirculation.” One gas our vehicles may make when they burn fuel is nitric oxide, which can play a big role in creating smog and acid rain.  It’s better for our planet if our vehicles aren’t spewing that into the air.   One inventive way of reducing it is by taking the exhaust and channeling it back to the vehicle’s air intake system. When it travels through the engine again, its composition is changed, and it comes out cleaner.  It also helps the engine be more efficient. The EGR valve can fail after a while, and some signs you may notice are the engine is miss firing, it may suddenly lose power or your Check Engine light may come on.  You may also see your fuel economy decrease or hear your engine knock. A bad EGR valve ... read more

There’s an important part in your vehicle that shields your timing belt, timing chain or cam belt from the debris and gunk that can be kicked up from the road.  It’s called the timing cover.  It’s important because the timing belt or chain is what coordinates parts of your engine called the camshafts and crankshaft.  When they’re in sync, all runs smoothly.  When they’re not, it can cause some serious engine problems. If your vehicle has a timing belt, without the protection of the timing cover, that belt can come loose from the timing gears or break.  If your vehicle has a timing chain, the cover keeps engine oil circulating around it which lubricates it.  When that starts to leak because of a bad gasket, the chain may not be getting adequate lubrication.   If your vehicle has a timing cover problem, you may notice engine oil leaking if a gasket is not sealing tightly.  You may hear a strange metallic sound coming f ... read more

Think of how many times you put your foot on your vehicle’s brake pedal every day.  And think of how much you rely on your brakes to slow down and stop your momentum.  When it comes to safety systems, your brakes are at the top of the list, and that’s why it’s so important to keep them in top condition. Brakes are something you make sure you keep maintained before they start showing signs of problems. Some of those signs are a grinding sound when you step on the brake pedal, your vehicle pulling to one side when you brake, you don’t feel your brakes stopping you as quickly as they used to, or you notice the brake light is illuminated on your instrument panel.  We ask a lot of our brakes.  They have to work no matter how hot or cold it is outside.  That means whether it’s sunny, snowing, raining, or icy; you’re traveling at highway speeds or school-zone speeds; or when suddenly you find yourself trying to avoid hitting another ... read more

A clean connection is a wonderful thing.  Think of a good cell phone signal or an airline connection with ample time and short distance to the next gate. Good connections are also important for your vehicle’s battery, and one secret to that is to make sure it’s periodically cleaned. If it’s been a while since you have had any service to your battery, bring it in so we can inspect it for any corrosion that might have formed.  Corrosion on the battery terminals will affect the connection between the battery and your vehicle’s electrical system. The amount of corrosion you can expect can be influenced by such things as the kind of climate you live in (dry or humid, warm or cold), if there’s lots of salt on the roads and how old your battery is.   We have tools and chemicals to safely remove the corrosion for an optimal electrical connection. In order to reduce the amount of corrosion re-forming on the battery, we’ll apply a special protec ... read more

Ever wonder how your vehicle’s engine is able to take the 12-volts from its battery and ramp that up to as high as the tens of thousands of volts it takes to fire its spark plugs? The secret is something called an ignition coil.  Most newer vehicles have an ignition coil at each cylinder, but older ones have a coil that serves all of the spark plugs.  There are telltale signs that you have an ignition coil problem.  As you might expect, one symptom is it’s hard to start your engine or it won’t start at all.  If your engine is misfiring or not running smoothly or you see the Check Engine light come on, those all could point to an ignition coil failure. Several things can contribute to ignition coil trouble in addition to normal wear and tear. Moisture and dirt may have gotten inside the coil, plus the heat and vibration of your engine over time can contribute to them going bad.  Bad spark plugs or plug wires can also be a cause.   While ig ... read more

Your vehicle’s engine runs hot.  It should, since it’s a series of little explosions that create the power that gets you going where you want to go.  To keep the engine cool, engineers have designed wonderful cooling systems that use liquid coolant, hoses, and a radiator to transfer the heat from the engine to the outside air.  In order for the system to work right, it has to have the right amount of that liquid coolant in it.  So that you know when the coolant has dipped below the correct amount, there is a sensor that keeps an eye on it.  When the coolant gets low, that sensor lights up a signal on the dash to alert you.  It may literally say “Check Coolant” or it may have a picture that looks like an old-style bulb thermometer sitting in liquid.  Your owner’s manual will usually tell you exactly what the one in your vehicle looks like. If that sensor system isn’t working right, you could wind up driving for a lo ... read more
