You may have noticed when you start your vehicle, you’ll see several symbols light up on the dash.  They’re different colors and shapes, and sometimes it’s hard to figure out what each of those symbols mean. They are warning lights and symbolize something in your vehicle is sending you a message.  It’s the result of today’s vehicles having lots of computers.  The good thing about having so many of these warning lights is they can let you know there’s an issue in need of attention before a more serious failure.   Sometimes it can be challenging to figure out what each light means, so here are some of the most common ones.  One looks like your vehicle’s engine from the side, the Check Engine light.  It alerts you to something as simple as a loose gas cap to a far more serious problem like an overheating engine.  When the Check Engine light comes on, bring it into our shop.  If it’s blinking or flashin ... read more

You may have never thought about it, but when you turn a corner, the wheels on one side of your vehicle turn at a different speed than the other side.  What is this magic? The answer is something called the differential.   A differential is a gear box placed between the drive wheels and needs lubrication to work.  Over time, that fluid can become contaminated, reducing its effectiveness. You likely won’t be able to detect any signs that it’s happening, though it may get a little noisier over time.  If you continue to drive with contaminated and degraded differential fluid, the gears may wear prematurely. That can also contribute to excess wear on the drive-wheel tires.    Two-wheel drive vehicles have one differential while all-wheel and 4-wheel drive vehicles will have two or three.   Your vehicle’s manufacturer has guidelines on how often you should have the differential fluid changed, and we recommend you follow those.   Chan ... read more

Maybe that little sticker on your windshield is giving you the reminder that it’s time for your vehicle to have an oil change.  You’ve thought, “Aw, I can skip this one and save myself a little money.”  When it comes to things you should never ignore on your vehicle, timely oil changes are number one on the list.   When the oil stays in your vehicle too long, it can accumulate dirty particles and begin to break down, defeating its lubricating properties.  Skipping or delaying an oil change can lead to far more expensive repairs down the line. Another is seeing a warning light and doing nothing about it.  Lights that advise you to check your engine or tell you things are running hotter than usual under the hood can be early warning signs to have a technician determine why.  Consider getting the answer earlier rather than later.  It could save you major headaches and money. Don’t skip having important fluids checked. That i ... read more

When you are comfortably headed down the road, you may not realize how many of the imperfections in the driving surface are being smoothed out, so you hardly feel most of them.  You can thank your shock absorbers for a lot of that comfort, and it’s important to make sure you keep your shocks in good shape. Newer vehicles have shock absorbers in the back wheels with another shock absorbing assembly in the front which may also have a spring component as well, called struts.   Shock absorbers not only keep your vehicle traveling smoothly and comfortably, but they also contribute to its stability.  Increased stability will help you be able to handle sharp turns and sudden stops more easily.  Shocks also prolong the life of your tires because they’ll grip the road more tightly.  And a nice side benefit of that is your tires should last longer.   After months hitting a lot of bumps on uneven road surfaces, eventually your shock absorbers will start t ... read more

Your vehicle has a few filters you might be somewhat familiar with.  There’s the oil filter that removes impurities from your engine’s oil, and a couple of different kinds of air filters that prevent contaminants from getting into the engine and the cabin. But you may not know that your vehicle also has a fuel filter. The fuel filter keeps contaminants such as particles and other foreign substances from making their way into the engine.  They can result from using lower quality fuel, driving in dirty or stop-and-go conditions, or simply what happens after many weeks and months of travel.  At some point, your fuel filter will start to get clogged up and won’t let the fuel get to your engine easily.  You might notice some signs of that: your engine doesn’t have the power it used to, it may misfire when you accelerate, it may be harder to start, or it may stall while you’re driving.  You may notice your vehicle vibrating a lot when yo ... read more

Heat is one thing that can damage a vehicle, especially if a problem isn’t taken care of soon.  Be on the lookout for signs that it’s getting too hot in some parts of your vehicle, starting with the most obvious one: the heat gauge/warning light on your instrument panel. When you see that heat gauge heading into the H zone or the warning light comes on, it’s often because your engine’s coolant is contaminated or running low.  It’s important to let a pro look at it soon before serious damage is done, The radiator is another trouble spot that can cause overheating.  It has a fan that needs to run properly, and it needs to be free of debris and dirt. Another radiator trouble spot is the core.  When it gets clogged and coolant isn’t circulating as it should, an overheated engine can be the result. Have your cooling system checked regularly, including its thermostat. Your water pump is another part of the cooling system that can wear o ... read more

We’ve all noticed them at one time or another on the street: a car or truck that drives by and the deep roar from their exhaust system sounds like a drag racer on the line.  But what happens when that rumble is coming from under YOUR vehicle? Well, it could be a sign your muffler needs attention. You may notice other signs if your muffler needs to be replaced.  Your fuel economy may have plummeted, the smell of exhaust is blowing into your cabin, or your engine isn’t running in its usually smooth manner.  Or you may notice your vehicle’s temperature gauge is showing it’s running hotter than usual. Mufflers sit under your vehicle, so they are exposed to all sorts of nasty things every day, and every season.  It may be dirt or salt from the road that gets kicked up on it, or you may rough it up with the potholes and speed bumps on the road.  Also, moisture from rain and snow combined with chemicals and brine can literally dissolve your muf ... read more

Before You Buy a Used Vehicle (Car Inspection before Buying a Used Vehicle) Perhaps this sounds familiar. Your vehicle seems like it’s been around forever, and you’ve decided it’s time to move on.  But when you check the price of new vehicles, the sky-high price tags have you considering a nice, pre-owned one.   So, you start looking through the ads and find a few prospects.  A couple look great, and the owners say they’re in like-new shape.  But most of us aren’t trained mechanics, nor do we have the equipment to run the tests to determine what’s right and what’s wrong with a used truck, car, SUV or van. 
 
The answer may be to consider having a trained professional perform an independent inspection on the vehicle you have your eye on. Some dealers may conduct their own inspection, but you are best served by having someone not associated with the seller thoroughly check that vehicle you have your eye on. A t

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

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
