If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent.  But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust.  If there's too much, it means there's a problem with the mixture of fuel and air.  The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency.  It does this constantly.  Many vehicles have multiple oxygen sensors.  Some have one close to the engine, another close to the muffler.  Two measurements are better than one since they allow readings to be more accurate.  You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail.  One thing that can damage them is contaminat ... read more

When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades.  You have spark plugs that require enough power so a spark can jump across a gap at its tip.  Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing. The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off.  That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers.  Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers. The next evolution came in the 80's when the distributor ... read more

You look at it every day, yet you don't really see it.  We're talking about your vehicle's windshield, and if you're not seeing it at all, that's probably a good sign.  The fact is that unless our windshields get fogged up, hazy or cracked, we don't pay all that much attention to them.  Considering how vital front visibility is in a vehicle, paying a little more attention to your windshield will pay off in the long run. Keep it clean!  In ancient times when gas stations had attendants who filled your tank for you, they used to clean the outside of your windshield while the fuel was being dispensed. In these days of self-serve gas, we don't have that luxury any more.  But it's a good idea to clean your windshield regularly, even when it's not filthy. If you let dirt build up on the outside, it acts like fine sandpaper when you turn on your wipers when the glass is dry. Really, try to avoid turning on your wipers unless your windshield is wet.  If you must u ... read more

If you've ever ridden down a rough road on your bicycle, you know how hard a ride it can be.  Yet drive down the same road in your car, truck or SUV and it miraculously will smooth out the ride.  That's because it is equipped with shock absorbers.  They are built to dampen impacts from road irregularities.  But after taking hundreds of hits from potholes, railroad tracks and curbs, your shock absorbers can wear out.  Besides the rough ride that can cause, there are other ways your vehicle's performance can be affected. When it comes to braking for example, you may take a longer distance to stop.  That's because shocks help keep your tires in contact with the surface of the road.  If the shocks aren't working properly, the tires won't make contact like they should.  So when you slam on the brakes, your vehicle will take longer to stop. Consider what worn out shocks are doing to your tires.  Since the bumps aren't being dampened as much, your ... read more

If you've ever felt your vehicle hesitate, go, then hesitate again, you might think there's something wrong with the transmission.  After all, it's not moving smoothly  down the road.  But there are plenty of malfunctions that can cause those symptoms, one of them being something you may have never heard of: the EGR valve. EGR stands for Exhaust Gas Recirculation. It's a system that channels small amounts of exhaust back into the engine to cool down the cylinders and reduce polluting gases.  Those include nitrogen oxides that can cause smog. The EGR valve regulates how much of the vehicle's exhaust gas is recirculated. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open.  When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air. The symptoms of a malfunctioning EGR valve include: Engine losing power Engine idling roughly Pinging and knoc ... read more

Let's face it.  Vehicles are complicated machines, each having thousands of parts.  And since they're subjected to heat, cold, vibrations, bumps and much more, these parts wear out and need to be replaced.  When your service advisor says you need a new part, you may have many options.  Let's say you need a new muffler.  One choice would be to get exactly the same part that was installed when the vehicle was manufactured.  The advantages are that it will perform the same way as the one it's replacing and will likely last about the same amount of time as the original. Some mufflers are made by the same companies that supplied the automaker when your vehicle was new (they call that an OEM part—Original Equipment Manufacturer).  And often those are the same as the part you'd buy from a dealer. A reputable vehicle service facility will know which ones these are because they replace mufflers all the time and do their homework. The good news is there a ... read more

If you've ever had a flat tire, then you know welcome it is to have a spare tire that is properly inflated, in good shape and easy to get to.  Problem is many of us don't even give our spare tire (if we even have one) a second thought. If you have an SUV or truck with a spare, it may be mounted outside the vehicle, such as on the tailgate or underneath the vehicle.  All of them, especially those underneath, take the brunt of debris, moisture, salt and dirt from the road surface, a potpourri of corrosion potential.  The hardware that holds these on can rust into a solid mess, making it hard for you or even a roadside assistance service to get off.  If you have one of those, have it checked and maintained at your vehicle repair facility on a regular basis.  They should be lubricated and cleaned periodically, and some recommend doing this service every time you have your tires rotated.  If the spare is the same size as the tires on the vehicle, it may be a go ... read more

When someone mentions driving like a maniac, they're not talking about you, surely? Besides the safety issues of aggressive driving, you should know that your vehicle will last a lot longer if you'll just mellow out a little.  Here are four traits good drivers follow if they want their vehicles to go the extra distance. Cool—The driver who can't wait to get to the next stoplight is just shortening the life of his or her vehicle.  Jackrabbit starts and uneven acceleration hurts your engine because the valves and cylinder heads are stressed more.  All of those moving parts will wear out faster as well as other components that are connected.  That means things like the air conditioner, power steering pump… just about anything that attaches by a belt or a pulley.  Oh, and you'll be generating more heat.  Heat is one of a vehicle's worst enemies. Warm—If you get in your cold vehicle which has been sitting overnight, start it up and rev the en ... read more

Winter and freezing temperatures present challenges for different parts of your vehicles.  For example, winter tires give you better traction on snow.  But some parts of your vehicle that may need special attention for winter are your windshield wipers. You may have found yourself in the middle of a snowstorm when your windshield wipers are doing nothing but streaking slush that ices up on contact on the glass.  Now you're more blind than you were before! Obviously being able to see during a snowy or icy winter event is important for the safe operation of any vehicle.  So keeping your windshield and rear window clean can go a long way to guarantee you can see your surroundings. Let's start with the wipers.  Blades that are good for hot weather may not be robust enough for freezing weather. You can buy special winter wiper blades that stay flexible during sub-zero temperatures.  The stiffer frames that hold them have a rubber covering that prevents ice and ... read more

It's pretty frustrating when your driver's window won't work.  You can't get your food at the drive-thru without opening the door, have a tough time using the ATM from your vehicle, can't have that fresh breeze blowing through your hair as you listen to your favorite road tunes. Plus, there's a safety factor.  Your windows provide an escape route in case you need to get out and the doors won't work.  Let's take a look at what's going on when your window won't operate. Most vehicles these days have power windows.  They have an electric motor in each power window and sometimes those fail.  They often give you a warning that they're on their last legs by making a noise or hesitating, so if you get a sign like that, have a technician check it out. Loss of power can also be due to a blown fuse, a bad switch or faulty wiring. All windows have something called a regulator that moves the glass up and down.  They have a lot of moving parts in them which can break ... read more
