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

Engine air filters may not seem like a big deal, but when they’re clogged up with dirt, dust, and insects, your engine could wind up choking for air and not delivering you the power and performance it was designed to give. There are actually a couple of air filters in your vehicle.  One filters the air going into the cabin (the cabin air filter), and the other filters air going into the engine.  That engine filter is the one we’re talking about. After several months and long distances traveled, your engine air filter accumulates the junk it’s preventing from getting into your engine. You may notice your engine misfiring, your acceleration may not be what it used to be, it may make strange noises, and the Check Engine light may come on. When you notice any of those signs, it’s time to bring in your vehicle to have us figure out what’s going on. We’ll visually inspect your air filter.  Keep in mind that your vehicle’s manufacturer ... read more

If your vehicle’s power goes to the rear wheels, then you have something called U-joints in the drivetrain. U-joints are connectors that allow the rotating power from your vehicle’s engine to deliver its power through a driveshaft to make the rear wheels rotate.  You need U-joints because the surfaces you drive on aren’t perfectly flat, and the driveshaft has to allow for some flexibility when you are traveling over uneven surfaces. As you can imagine, the U-joints have to move and flex a lot as your vehicle is going down the road.  They have bearings in them to allow that flexibility, and those bearings are lubricated when your vehicle is made.  Some U-joints have lifetime lubrication and are not designed to be serviced.  When they fail, they have to be replaced.  Others have grease fittings on them that need periodic lubricating by a technician at intervals recommended by your vehicle’s manufacturer.  There are signs you can look ... read more

What's the dif? To an automotive technician, it's the differential, a part of your vehicle that helps direct power from the engine to the wheels.  The differential is a gearbox that enables the drive wheels to turn at different speeds (they do that when you turn).   Inside the differential is a fluid that makes sure those gears and other parts are lubricated since there are a lot of metal moving parts in there.  (Your vehicle may have more than one differential in it depending on the drivetrain.)  As you can imagine, it's important that the lubricant in those differentials do its job.  Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down. So, it's important to have the differential fluid exchanged every so often.  Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km ... read more

We all want to breathe clean air and keep our planet green.  One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test.  That’s because these vehicles can be big polluters.   Everyone wants their car to pass the test so they can continue their day-to-day driving routine.  But then comes that one day when they tell you your vehicle has failed.  Why does that happen? One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!).  The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go. Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air.  There are many reasons the catalytic converter may not ... read more

Tires are so reliable these days that few drivers pay much attention to them.  But tires wear out.  They have a tough job since they are the only point of contact between your vehicle and the road.  They have to get your vehicle going from a stop, keep it going, make sure it is headed in the direction you want it to go, and –importantly – slow and stop it.   The only time many drivers think about their tires is when there's a problem, such as a flat.  Or, they may lose control when they find their vehicle isn't stopping or steering like it used to.  One major safety organization estimates that 1 out of every 11 crashes is related to a tire issue.   Many of those problems are caused by tire tread wearing out.  The rubber is worn off by friction after hours and hours on roads.  The sidewalls can also be damaged by your tires hitting curbs, potholes, or other debris. Plus, rubber ages as time passes.  We recommend you let us in ... read more
