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

Colder weather brings out the worst in a vehicle's battery. On a very cold day, you may have experienced that your engine cranks slowly when starting. But while it may be the battery itself, it may also be the parts that transfer the power to other the other electrical components, the battery cables. After all, you have to have some way to get the current out of the battery and out to where it needs to go. Battery cables have a couple of enemies: corrosion and age. You may have looked under the hood and noticed a light-colored powder or crust around the terminals. That's what happens when acids corrode the ends of the battery terminals. Corrosion inhibits the connection and may reduce the amount of power getting to the electrical accessories to the point where they are not working correctly, if at all. Here are some symptoms of problems with your battery cables. You might notice a clicking sound when you turn the key, some of your vehicle's electrica ... 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 may be one of those romantics who don't like giving (or getting) practical gifts for special occasions. Just wait until one of those gifts helps you out of a big predicament in cold weather, and you realize that practical gifts can be life savers. Here are a few things you may give the cold-weather driver in your life—or suggest to someone else to give you! A portable air compressor. If you've ever had a flat and you can't imagine trying to change a tire on a snowy, winter day, this may just get your tire pumped up enough to drive over to the repair facility. Some are fancy and pricey, some are only a few bucks. They plug into the cigarette lighter/12v outlet and will take a few minutes to pump up your tire. But it could save you a tow. Portable jump starter. These are relatively small power units (they easily fit in a car trunk) that can jump start your vehicle that has a dead battery. Some even have an air compressor built in. If you've ... read more

Most light vehicles (under 10,000 pounds/4,500 kg) in North America sold from 2008 model year on have a feature that many people are confused about. It's the tire pressure monitoring system (TPMS). You may have some experience with it yourself if you own a newer vehicle. Vehicles with TPMS have sensors in each tire that are supposed to warn the driver when tire pressure gets dangerously low. That's important because tires that are significantly under-inflated can cause very serious accidents. Unfortunately, many drivers think the TPMS does all the work keeping track of tire pressure. To them, as long as the warning light or gauge isn’t giving a warning, the tires must have the proper amount of air pressure in them. That's not the case. Tire pressure monitoring systems aren't all created equal. Some give you a digital readout of the pressures in each individual tire. But many simply have a warning light that looks like the cross sect ... 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

You know you have an accelerator pedal; step on it and your vehicle is supposed to go. But did you know there is a part in your vehicle that keeps track of where the throttle is? It's called the Throttle Position Sensor, or TPS. The TPS is a sensor that helps your vehicle figure out the right mix of air and fuel is reaching your engine. It does that by keeping track of the throttle and sending that information to your vehicle's computer. Other factors play a role in how well your engine is performing, including air temperature, how fast the engine is turning over and air flow. When the TPS isn't working right, you may find your vehicle won't accelerate or doesn't have the power you're expecting when you press on the accelerator. In some cases, it may accelerate on its own. Sometimes your vehicle won't go over a certain speed. Your Check Engine light may go on. Any of these symptoms should be checked out soon. If your TPS stops working rig ... read more

It's bad enough in cold weather when ice and snow block your visibility. Add to that fog on the inside of your windows and you could be driving blind. So here are a few tips on how to keep your windows from fogging up when there's a chill in the air. You probably know fog is really condensation, when moist, warm air meets a cold surface and turns to liquid. If your windshield fogs up, you probably turn on your windshield defroster. Most defrosters blow heated air on the windshield glass to warm it up so it won't condense the moisture. Many also turn on the air conditioning to reduce the moisture. That same strategy can work on the rest of the windows. First, turn up your heater's temperature setting. The hotter the air, the more moisture it will hold. Also, turn off the "recirculating" setting since you want all outside air to come in. Then switch on the air conditioning. It will remove the moisture from the outside air that i ... read more

If you hear a squealing noise when you turn your vehicle, it's trying to tell you something is wrong. After all, it never made that noise before, right? The sound you hear may becoming from a few sources. Let's take a look (or a listen) to some of the possibilities. First, you almost certainly have power steering in your vehicle. Without power steering, you practically have to have arms like Arnold Schwarzenegger to turn, so automakers have technology to assist your steering, either mechanically or electrically. For a long time, the most common power steering has been hydraulic, using a belt to supply power from the engine that turns a power steering pump full of a fluid that helps you steer. Sometimes that fluid gets low because of a leak or some other problem. The belt could wear out and start squeaking, and you might feel the steering start to become harder. Your service repair facility can figure out the problem and offer some solutio ... read more

If you've ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents. There are many things that can cause a vehicle to give off a gasoline odor. One of the easiest to track down is the gas cap. It could be missing or it doesn't seal well any more (they do wear out). That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis. Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It's the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they're made out of rubber or metal). They can leak gasoline, too. It's always a good idea to check the garage floor for any gasoline puddles. Note the location of the puddle in relation to ... read more
