Always on Guard (TMPS)

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated.  If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident. All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS.  One system uses small sensors in the tires that continually check the pressure in each tire.  That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire.  Another system works with your antilock brake system to measure the size of your vehicle’s tires.  When one wheel is going faster than another, it will spin faster. A computer sees that and alerts ... read more

A Door No One Can Step Through (Fuel Door Repair and Maintenance)

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you. When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time. A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it.  You probably want to take care of ... read more

Keeping Your Cool (Coolant System)

No matter what the weather is like outside, your internal combustion engine expects to keep its cool all the time, even when it's really cold.  That's because engines create the power that moves you to your destination by a series of tiny explosions of a fuel and air mixture. In turn, that generates a lot of heat in a small space. Your vehicle has a complete cooling system with a lot of different parts that work together to keep the temperature at a point where the metal engine parts won't heat up enough to warp.  Its lifeblood is coolant, a liquid that circulates through the engine (and, in most vehicles, the transmission, too) through a series of hoses and tubes.  In order to get rid of the coolant's heat, your vehicle has a part you probably recognize: the radiator.  It does what its name proclaims: radiates heat.  The radiator has a series of thin metal fins that coolant goes through, and when outside air passes over them, the heat is dissipated from the ra ... read more

Out with the Old (Vehicle Parts that Wear Out)

Some drivers don't pay any attention to their vehicles until something breaks.  Others take them into their service repair facility for maintenance even before a problem develops.  Still, even if you fit into the second group, there are some parts on a vehicle that will simply wear out over time. Your vehicle has gaskets in several places.  They use a flexible material to seal the gaps between metal parts that fit together. After time, that material shrinks or gets brittle and fails.  Eventually, after time, you will have to get gaskets replaced. Same goes for belts.  Your engine has belts that help take the mechanical energy of the engine to drive other parts such as the generator and air conditioner.  Heat and age will eventually cause these belts to wear out or break, so you'll need new ones at some point. You'll also find yourself buying brake pads.  As much as you may try to go easy on them, brake pads work by wearing off a little bit of them eac ... read more
