Your vehicle's engine is probably the first thing that comes to mind when you think of a power plant.  But it has another power source that is vital as well: the alternator. The alternator is what puts out the electricity that powers such things as your lights, power windows, sound system, and navigation.  Maybe you've started seeing those electrical components behaving in strange ways.  Maybe your power windows are going up and down a little bit more slowly than they used to.  Or perhaps your engine doesn't start as easily or is misfiring.   Other signs of a failing alternator are headlights that are either brighter or dimmer than usual.  If your battery keeps going dead, it could be that the alternator isn't recharging it.   The alternator has to get its power from somewhere, and in vehicles with internal combustion engines, that power comes from a drive belt powered by the engine.  Sometimes that belt can fail.  If you hear a whining soun ... read more

Ever wonder how your vehicle’s transmission is connected to your wheels? After all, when you hit a pothole or some other uneven part of a road’s surface, there has to be something that can maintain the connection between the transmission and the wheel yet keep everything moving at the same speed.  That very cool device is called a CV joint, a kind of driveshaft running to each wheel.  The CV stands for constant velocity because it keeps the drive wheels moving at a constant speed (velocity).  They’re used mostly on front-wheel drive vehicles but also in rear-wheel and all-wheel drive vehicles. The joints move up and down and adjust to bumpy surfaces.  Plus, they are covered in a rubber boot which protects them from road debris and also holds lubrication in.  There’s a CV joint and boot on the transmission side and one on the wheel side.  Unfortunately, the spot that usually fails first is that rubber protective cover (the boot).&nbs ... 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

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
