You may have heard someone say they just got the air filter replaced in their vehicle.  But did you know your vehicle has two different major air filters and they both perform quite different—but very important—duties? Today’s vehicles have a cabin air filter, and an engine air filter.  The engine air filter cleans the air that enters your engine so it can run better, and so contaminants don’t foul vital parts.  While the cabin air filter keeps the air inside the vehicle’s cabin clean, the place where you and your passengers sit.   It is important that you have each of these types of filters changed at regular intervals, or earlier if either shows signs that they’re contaminated. Your vehicle’s owner’s manual often will recommend how long that interval should be. First, let’s look at the engine air filter. Your vehicle’s manufacturer will offer guidelines on how often you should change the engine air filter ... read more

It’s always a good idea to keep your cool, and that’s especially true when it comes to some components of your vehicle.  One is the engine.  It’s hot under that hood thanks to the mini explosions that are occurring in the internal combustion engine when it’s running.  Your vehicle has a cooling system which takes the heat out of the engine by moving a liquid coolant to a spot where the heat can escape (the radiator).  The part that keeps that coolant moving is the water pump, which could probably be more accurately called the coolant pump since water is only one component of the fluid that does the cooling. If the water pump fails, your engine can overheat quickly, and that can cause significant and expensive damage to your vehicle.  Water pumps can be driven by belts (mechanical) or electricity (electric). Your vehicle’s manufacturer recommends mileage intervals when you should consider replacing your water pump even if seems to b ... 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

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

Regardless of whatever current gas prices may be, if you could use less gas, wouldn’t you? Well, here are 10 things that are robbing you of better fuel economy that you can change for the better:    •    Not enough air in your tires.  Underinflated tires have a smaller rolling diameter and more resistance to rolling.  Keep them inflated properly, plus ask us about more fuel-efficient tires.    •    Faulty oxygen sensor.  A faulty or dirty oxygen sensor can cause your engine to burn too rich a mixture of air and fuel.  That can also trigger a Check Engine light.  Have us check yours.    •    Oil age and type.  Contaminated or improper viscosities of engine oil can create more resistance in your engine.  Have regular oil changes and consider newer high-mileage oils.    •    Bad wheel alignment.  When your wheels aren’t lined up straight ... read more

If you’ve ever driven a bicycle with hand brakes, you’ll probably understand how the brake pads on your vehicle work.  Bicycle brakes use a system that squeezes the bike wheel’s rim with a pair of cushioned pads activated by your hand squeezing the hand brakes on your handlebars. The friction of those pads stops the wheel. That’s the same principle used for the wheels on your vehicle.  Step on the brake pedal and that causes pads to put pressure on discs in the wheels called rotors.  Those pads create friction and stop the wheels from turning. Brake pads in vehicles are made from several different materials.  The pads most commonly used are ceramic or a combination of metals. The friction that stops your vehicle generates heat and wears both the pads and, eventually, the rotors, too.  That means that, over time, both are going to need replacing to work properly.  One sign brake wear is getting noticeable may be  when you hear s ... read more

When it comes to ease and precision of steering, today’s vehicles are engineering marvels.  One of the keys to just how good steering is lies in the refinement of power-assisted steering which we know simply as power steering.  At the heart of the system is an electrically or belt-driven power steering pump.  It can apply hundreds of pounds of hydraulic pressure to the steering gear so you can turn your heavy vehicle with little effort. The more time and distance your vehicle travels, the more wear your power steering pump experiences. One sign your pump may be aging is that you hear a whining or groaning sound coming from your wheels when you turn. You also may feel a vibration through the steering wheel, or the wheel is harder to turn or responding more slowly than normal.  Another sign of trouble with the power steering pump is power steering fluid (reddish-brown) leaks on the ground around your vehicle. If you encounter these symptoms, have us check your v ... 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

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

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
