If someone told you there was a fairly inexpensive way to improve your vehicle's handling, fuel economy and extend the life of your tires, you'd probably ask, "What do I have to do?" The answer is to rotate your tires.  But you have to do it regularly. A lot of drivers think skipping tire rotation is a way to save money.  But when you don't rotate your tires, they will almost certainly wear unevenly.  That's because when your tires touch the surface of the road, the friction and traction causes miniscule parts of the rubber to come off.  And that process isn't exactly the same on each corner of your vehicle.  Some vehicles have the drive wheels in the front, some in the rear and some on all wheels. Rotating your tires at regular intervals minimizes the differences in the way the tires wear.  The amount and pattern will be spread out equally if your tires spend time at all different positions.  The more even the wear, the more consistent traction, hand ... read more

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies.  Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s. Today's most hig ... read more

Ever wonder what one of the best things is to ever happen to your vehicle's engine?  It's the little thing that usually looks like a can, the oil filter. Just like your kitchen sink strainer filters out errant particles of food from clogging your drain, the oil filter cleans out small particles that could cause your engine harm. Your engine operates in a dirty, hot environment and gathers a lot of tiny contaminants like dirt, dust, little metal shards and unlucky bugs that get sucked in.  Get those things circulating in your engine and those little particles can cause friction, which starts wearing out those finely machined metal parts.  You know how important it is to change your oil regularly.  It's vital that you change your oil filter at the same time to keep the oil as close to brand new as possible. Most oil filters look like a metal can with some holes in the bottom.  Inside there are carefully chosen materials that can screen out the contaminants while ... read more

Your vehicle may be wearing boots right now and you might not even know it.  They're called ball joint boots.  They're actually protective, flexible things that protect parts of your suspension (called ball joints) from all the hazards the road can fling at them.  If one of those ball joint boots fails and you don't get it replaced, the ball joints themselves could wind up failing, a repair that can be even more expensive.  Ball joint boots not only keep things like rocks, salt, water and dirt out of your ball joints, they also help the ball joints keep their lubrication inside and working properly.  To do that, the boots have to be made of a flexible material, sometimes rubber, sometimes a synthetic.  They do take a beating, exposed to temperature extremes and debris, and eventually they can tear or crack just because of their age.  Unless someone is keeping an eye on your ball joint boots, you may never know there's a problem.  That's why when ... read more

When the leaves fall, you might take a sightseeing trip to see them at peak color.  Or you may simply live in a spot where there are a lot of trees.  When those leaves get wet, you'd be surprised to learn just how slippery they can be.  We all know ice is slippery to drive on.  What causes tires to slip on ice is a thin layer of water that comes between the road and your tires.  Wet leaves can have the same effect.  The surfaces of leaves are super slick when they're dry, even worse when you add a little moisture.  There's one other thing about leaves.  They are smaller than each tire's footprint, so your tread grips the pavement with uneven traction. One study showed that your stopping distance can more than double on a surface covered with wet leaves when compared to that same road when it's dry.  Double! That can spell trouble.  So if you find yourself heading into an area with wet leaves on the road, slow down before you get into a ... read more

There's nothing quite like getting in your vehicle on a hot day, switching on the air conditioning and having warm air blow out of the vents.  You may have had no problem for months and then, one day, you are driving around in a sauna. You're hot stuff, but not in a good way! So what goes wrong when the AC isn't working? It could be a lot of things because the system has many different components.  One thing that's a common cause is the vehicle is low on refrigerant (it used to be called Freon).  If that's the case, it's not as simple as simply adding more.  Sure, it may fix it quickly for a short time, but it's more likely than not that the refrigerant will just leak out again. The original Freon used in air conditioners was destroying the Earth's ozone layer, so that's not used much any more.  But the one that's currently used also contributes to global warming, so it's important that as little of that escapes as possible.  So a technician will determine ... read more

Quick question.  Which is tougher on a vehicle's battery, the heat or the cold? Believe it or not, it's the heat.  Think about it.  The battery often sits in the engine compartment next to that motor generating lots of heat.  That can accelerate corrosion in the battery and may even cause water in it to evaporate.  That will weaken the cranking power of your battery and shorten its life span. To take care of your battery, here are a few suggestions.  It's a good idea to have it checked out to see what shape it's in.  At your vehicle service facility, they have diagnostic equipment that can evaluate its condition.  That can help you know how long you can expect it to last before having to replace it.  At the same time, you should have your charging system evaluated.  If your battery is not getting charged properly, it can be in great shape but not very useful when it comes to starting your vehicle.  A technician will also check the ... read more

It's one of those things that can happen on a multi-day road adventure or a quick trip to the grocery store.  You hit a pothole, go too fast over a speed bump, nail a curb.  When it happens, you think, "I wonder if that was hard enough to do any damage?"  But things seem ok and you continue on your way.  Keep in mind that any blow to your vehicle's suspension can throw it out of alignment.  It can be a hard knock from the road or from another vehicle, such as being involved in a minor accident.  When your suspension is out of alignment, it means that the wheels aren't all pointing where they should.  And after a while, it can make your tires wear unevenly and cause problems with steering and handling. Let's go back to that pothole or curb you hit hard.  Even though you think there was no damage done, if you wait until you see tire wear, you may need to replace all four tires, not an inexpensive proposition. That's why it's a good idea to make sur ... read more

Let's say you live in a cold climate where the snowy, icy weather challenges you to clear the salt and debris tossed up on your windshield.  You push your windshield washer switch expecting a good stream of fluid so the blades can wipe the glass clean. Yet nothing comes out.  Nada, zip.  What's going on? You know you filled up the windshield washer reservoir within the last week or so.  Well, there could be a few things causing your windshield washing system to fail.  One culprit? The hoses that are supposed to carry that fluid from the washer pump to the spray nozzles may be frozen, or maybe they're cracked and leaking. It could be the nozzles themselves are stopped up, either iced up or jammed full of debris.  Your windshield wiper/washer switch could be worn out or the electrical system may not be conducting power to the washer pump.  It's important that this system work properly, especially on days when the sun may be in front of you and your wind ... read more

It's no fun when your vehicle just doesn't run the way it used to.   You may notice (especially in cold weather) the engine won't start easily or when it does start, it doesn't run smoothly. It may not have much power at all. You also may have had to stop at the gas station more often, a sign your fuel economy isn't what it used to be.  There could be a few different things that cause those symptoms, but one culprit could be a bad ignition coil. The coil takes the voltage from your battery and multiplies it before that power is sent over to a spark plug. That allows the plug to fire off a good jolt of electricity that ignites the fuel in your cylinder and powers the engine.  There's usually one ignition coil for each cylinder (or sometimes for a pair of cylinders). If only one of them is not pushing out enough electricity, it can cause big trouble with your engine performance.  Other signs of a bad ignition coil include engine backfire, an oil leak and your Che ... read more
