If you’ve ever stepped on your brake pedal and felt your vehicle vibrate, that’s a signal that you shouldn’t ignore.  A pulsating brake pedal is a sign that something is wrong.  Braking action should be smooth, sure, and quiet, not shaky and noisy. Most newer vehicles have disc brakes, called that because they have a round, flat disc connected to each wheel.  Those discs are the rotors. Other parts called brake pads are squeezed against those discs when you press on the brake pedal. Remember that vibration we mentioned? That can be caused by the rotor not having a straight, true surface. Rotors can heat up from friction and warp.  They can become thinner from constant wear.  Rotors can rust from the elements they’re exposed to, such as rain, snow ice, and salt.  They can get grooves in them from so many contacts with the pads.  The signs of worn rotors are vibrations, grooves on the rotor (which you can see sometimes through op ... read more

When it comes to oil changes, things are really changing.  Most newer vehicles require synthetic oil, and while it costs more than conventional oil, it doesn't need to be changed as often. When conventional oil was the only game in town, you changed your oil every 3,000 miles/5,000 km. But as technology in newer vehicles has rapidly changed, so has oil technology.  Synthetics have been around since the seventies.  Even though they start with a conventional oil base, they are engineered in a chemical processing plant with properties that allow them to keep your engine lubricated at very high temperatures.  They are more uniform and consistent. Synthetic oil doesn't break down as easily, so it lasts longer than conventional oil.  And synthetic oil can flow more easily, even in extremely low temperatures.  As you can see, it has performance advantages at both temperature extremes. Generally, in recent years automakers have been shipping most of their vehicles ... read more

You know how exposing your skin to sunlight can cause sunburn and other unhealthy things.  Sunlight can also create major problems for your headlights.  After they've been exposed to ultraviolet light, acrylic headlights can yellow and fog due to oxidation.  And when that happens, less light can pass through the plastic, reducing the effectiveness—and safety—of your headlights.  It's not just the UV light that causes headlights to turn cloudy.  Road grime and debris gets kicked up and can scratch the plastic, diffusing the light that should pass through them when they're clear.  Plus, when your vehicle was new from the factory, the headlights had watertight seals all around to prevent moisture from getting into them and fogging them up with water vapor.  Just like clouds can hide the sun, tiny water molecules can diffuse the light from your headlight bulbs.  Sure, you could buy replacement parts and start fresh.  But the good new ... read more

If you drive a vehicle with a gasoline engine, thank the spark plugs for igniting the gasoline/air mixture in each cylinder that keeps your vehicle traveling smoothly down the road every day.  Your spark plugs work hard, firing thousands of times in a well-choreographed order, and you usually don't pay much attention to them until one of them stops working the way it should. Signs that spark plugs are wearing out include: Engine runs more roughly than it did Vehicle doesn't start as easily as it used to Vehicle hesitates when you press on the accelerator Your fuel economy has gotten worse When a spark plug stops working altogether, you will find your engine has likely lost a lot of its power and isn't running smoothly.  Your Check Engine light may  come on.  Then it's time to head to come to our service center to have it diagnosed. If your plugs need to be replaced, they're usually done all at the same time. And if your vehicle has spark plug wires, experts recomm ... read more

When you get in your vehicle, how does it smell? If it's not so nice, it may be time to have your cabin air filter changed. It's not the same one that filters out the air used in the engine.  The cabin air filter screens out dust and other particulates from the outside air so when it enters the cabin, you don't have to breathe them in when you're driving.  Maybe your commute finds you traveling along dusty rural roads, or maybe you pass by some city factories that have smokestacks spewing out smoky exhausts.  Or in spring, maybe you notice your allergies acting up because of the pollen in the air.  The cabin air filter will remove a lot of those things. The more it filters out, the more those small particles add up.  That reduces how much airflow the heating/air conditioning system can handle, and you may notice not as much air is coming through your vehicle's vents.  That can also be a sign you need your air filter replaced. Our technicians will remove an ... read more

You may be fanatical about keeping the outside of your vehicle clean.  But what about what's under the hood? Have you ever thought about how dirt and grime may be affecting your engine's components? One of the most important parts under your hood to keep clean is your vehicle's battery.  With a daily barrage of dirt and moisture, outside parts of your battery can corrode, namely the cables and terminals. Gases vented by batteries can also promote corrosion.  That can create connection problems and affect your vehicle's electrical system.  If corrosion is not cleaned off, it may damage wires and terminals so badly that they will stop properly conducting electricity.  At that point, they may need replacing. When you bring your vehicle to us for a battery inspection and cleaning, we will remove any corrosion and put corrosion-resistant protection on each post. A technician will also visually inspect your battery.  Plus, we can test how much life is in your ba ... read more

Your vehicle gets its power from burning fuel, usually gasoline, and it counts on something called fuel injectors to send gas to the engine in a spray that is easy to ignite.  It’s a precise operation, and when it’s working well, you have plenty of power and an efficient engine. But after time, contaminants in the fuel system may prevent the injectors from spraying like they’re supposed to.  They can also shoot contaminants into the engine.  One sign that could point to dirty fuel injectors is a misfiring engine. Misfires can be caused by several things, so it’s a good idea to bring your vehicle to us so we can trace the cause. Another sign is that your fuel economy has gone downhill or your engine doesn’t have the “pep” it used to. If we discover that your injectors are clogged or not working the way they should, we can clean them to get rid of those contaminants to restore your engine to its top performance.  When you brin ... read more

After months of postponing travel far away from home, a lot of us can't wait to hit the road and scream "Road Trip!" again.  But how long has it been since the vehicle you're planning on taking has had a thorough inspection? And is it roadworthy for several days on the highway? Time to schedule a professional trip inspection in our service center.  When it comes to long trips, before you go, make sure you can stop.  We can perform a break inspection.  Our technician will visually inspect your brakes for wear and how much life is left in the brake pads and rotors.  They'll also check your brake lines and fluids for fitness and fill. If it's going to be a long trip, it's important that your engine stays lubricated.  The technician will see when the last time you had an oil change, check the levels and inspect the system for leaks.  If you are close to needing an oil change, it's best to have it done before the trip because no one wants to interrupt a va ... read more

It's easy to get letters like PVC and PCV mixed up.  PVC is a plastic that's used in a lot of things, especially plumbing pipes.  And PCV is a valve that helps your engine burn off excess fumes rather than having them pollute our atmosphere.  PCV stands for positive crankcase ventilation.  When your engine ignites gasoline in the cylinders, some of the gases produced make their way into the crankcase, where oil is held to lubricate the engine.  In earlier days, those gases would be vented out through a hose and go directly into the air.  It was a waste of gasoline (since about three-fourths of the gases were unburned fuel) and a nasty source of pollution. So engineers devised a one-way valve that directed those gases back into the engine's air intake system to be burned again.  After a while, the PCV valve can get clogged up with gummy oil.  Not only does that reduce the recirculation of the gases, but it can also cause pressure in the crankcase ... read more

For drivers, S stands for safety.  And there are three other words that start with S that are all equally important: starting, stopping and steering. For your vehicle to be at its safest, all three functions must be in top shape.  Steering is one of those things we take for granted.  After all, you turn the wheel and your vehicle changes direction. But sometimes you might notice your steering is a little off.  Maybe you've noticed you turn your wheel slightly and your vehicle doesn't turn. You may feel a little vibration in the wheel that increases when you go faster.  You may hear a little squeak from the wheels when you steer and you may notice your tires aren't wearing evenly. These are signs that your tie rod ends may be failing. Tie rod ends help connect your vehicle's steering mechanism to the wheels.  They can wear out after you've hit one too many potholes or just from constant use.  They can cause sloppy steering and loose handling, and they ... read more
