If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you.  No, really, it is.  So listen to what it's saying and you could avoid a much more costly repair down the road. A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on.  One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels.  Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems.  Think of it.  Hydraulic power steering has many components that need to work in tandem.  The power steering fluid may be too old and contaminated.  Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening. Other causes of grinding while turning can be problems with the suspension in the front.  Yo ... read more

You may remember a song that went, "Objects in the rearview mirror may appear closer than they are." While that was a song about life's lessons, there are a few things we should all know about how important rearview mirrors are to safe driving. While new electronic devices are helping drivers be aware of surrounding traffic in high-tech ways, the good old rearview mirror is still a dependable way of letting you know what's around you.  There are usually 3 on each vehicle, 1 attached to the windshield inside and 2 attached outside on each of the front doors. It's important that they be adjusted properly before you start driving (not while you're driving). Experts say the windshield rearview mirror should cover the area behind the vehicle while the outside mirrors should not simply duplicate that view but extend it to the sides, where blind spots normally are. Your rearview mirrors must be able to hold the positions they're adjusted in; it there's play in them or they move around, y ... read more

You know how heavy your engine and transmission are, so you can imagine how tough the parts that hold them onto your vehicle's sub-frame must be.  Not only must they support the weight, they also have to isolate vibrations and noise from the passenger cabin.  Pretty tall order, wouldn't you say? The parts that face that task daily are called the motor mounts, or engine mounts.  They are usually made of rubber with steel brackets.  Others contain a liquid for vibration and sound isolation.  Most vehicles have three or four motor mounts, and while rubber or hydraulic liquids do a good job of damping the vibrations from the engine, they also have their limitations.  The problem with rubber is that it gets old and brittle.  Plus, if there's an oil leak anywhere in your engine and oil gets on the rubber motor mounts, rubber will deteriorate even more quickly.  As for the liquid motor mounts, they can develop leaks and stop working.  Here are sign ... read more

If you park your vehicle outside, you are exposing it to all sorts of critters that would love to use it for nesting, food storage and shelter.  There are plenty of pictures online of people who've discovered there was more than an engine under the hood.  In one case, the driver of an SUV started to smell a slight burning odor when she was driving.  Turned out to be 200 walnuts and a lot of grass had been stored there by some industrious squirrels preparing for the upcoming cold weather.  The SUV owners had their vehicle inspected not long before this happened, but it doesn't take some animals long to set up house in what they think is the ideal spot to make their winter home.   Obviously, that can create problems.  Squirrels, mice, rats and other small animals can chew through hoses and wires.  Plus what they store as food and nesting material may prevent engine parts from moving the way they are supposed to.  Imagine a radiator fan that wo ... read more

Your vehicle may be like that famous battery bunny, the one that just keeps going and going.  But while it may seem sometimes like you never need to take your vehicle in to be worked on, there are some things you should keep your eyes, ears and nose out for. They are warning you about something that needs attention at your vehicle service facility. If a warning light is on, don't ignore it; do something about it.  There are warning lights for battery, oil, engine heat, tire pressure… you name it.  And the manufacturer put them there for a reason.  They're telling you something isn't normal. So when one goes on, have it checked out soon, especially the blinking Check Engine light.  The earlier you have any warning light issue diagnosed, the more likely you are to avoid a more serious problem. If your vehicle is vibrating or shaking, it's not only annoying, it could signal trouble.  You can bet your vehicle didn't do that when it came out of the fact ... read more

There are some dashboard lights you should pay more attention to than others.  One is the air bag light.  If it's on and your vehicle is in an accident, your air bags probably won't do their job. Automakers began installing air bags in the late 1990's since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt in combination with an air bag gives passengers the best chance of surviving a crash and minimizing serious injury. The air bag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated air bag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off." Different things cause the air bag light to come on.  Your vehicle may have been in an accident during which, while the air bags didn't inflate, crash s ... read more

So you thought you only had two brake lights.  Look again and you'll see one in the center at a higher level than the two on either side of the vehicle.  They're sometimes in the inside of the vehicle behind the back window, or they could be in the deck lid, on the roof or on the spare wheel carrier, But why is that third brake on your vehicle? Experts say it helps prevent rear end collisions. Tests done by installing the third brake light in taxis and fleet vehicles showed fewer rear end crashes in the ones that had the extra light. The third brake light was mandated in new passenger cars in 1986 in the US and Canada.  The requirement was added to new light trucks and vans in 1994. Sometimes it's difficult to know if your third brake light is even working.  Many vehicles have bulb warning systems that alert you to non-functional bulbs, but not all do. Your vehicle service facility will often check to see if all your turn signals, taillights and headlights are worki ... read more

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S.  Sulfur. Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up.  If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe. There's another possi ... read more

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception. The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit.  But it's not just the diagnostics that are computerized.  Everything from your vehi ... 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
