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

Ever wonder how all-wheel-drive or 4-wheel-drive vehicles get the power from the engine to the front and rear wheels? The magic happens in what's called a transfer case.  In some all-wheel-drive vehicles, it's sometime called a power take-off unit, or PTU. Inside the transfer case is a set of gears.  And to keep those gears meshing smoothly, they have to be lubricated and kept cool.  What does that is called transfer case fluid. Depending on your vehicle's type of transfer case, it is filled with either an automatic transmission fluid, a gear oil that's a bit thicker or transfer case fluid designed to be use for your transfer case. As happens with all lubricating fluids, the transfer case fluid has things in it that break down the older they get.  They have corrosion inhibitors, detergents and anti-foaming agents that keep the lubricant from getting air bubbles in it. Transfer cases don't have filters in them to clean out impurities. If you don't have your transfer ... read more

Maybe your vehicle feels like Breaking Bad.  In other words, when you brake, things are bad.  You may find it takes you a longer distance to stop, you feel a vibration, or it’s pulsating when you depress the brake pedal, or perhaps your vehicle pulls to one side. Those can be symptoms of failing brake drums.  While a lot more vehicles these days have disc brakes, many vehicles still have brake drums, almost always in the rear wheels. The drum is a cast iron shallow cylinder that surrounds the other parts, including curved brake shoes that press pads against the drum to slow you down or stop the vehicle. Any time you have things going wrong with your brakes, you should get them fixed soon.  Safely operating any vehicle depends on having the brakes be able to slow and stop you dependably.  It can make the difference between avoiding a collision and having one.  When you bring your vehicle in, a technician will inspect your braking system. Depending on ... read more

Ask just about any driver about one thing they fear seeing inside their vehicle and they'll say it's the Check Engine light coming on. You know, that little light on your instrument panel that is in the shape of a vehicle engine, often accompanied by the words Check, Check Engine, Check Engine Service, or Service Engine Soon. There are so many different reasons that light shows up, from something as simple as a loose gas cap to a more serious problem that requires immediate attention.  The Check Engine light comes on because a component of your vehicle's onboard diagnostics system is telling you something isn't operating normally. Your vehicle has a lot of sensors built in, all tied together by computers.  When the sensors are showing that things somewhere aren't functioning the way they should be, they alert the vehicle's diagnostic computers and tell you something's amiss. The simple rule is if the Check Engine light is on steadily, it's so ... read more
