Whether it's the one in your lawn mower or car, all piston engines operate on the same basic principle. They use a four-step process of intake, compression, combustion, and exhaust to convert fuel to energy.

If you hear a high-pitched squeak emanating from the front wheels while the car is in motion, it's probably a 'brake wear indicator' telling you it's time to replace your brake pads. Don't let this minor repair job turn into an expensive brake overhaul.

There can be many reasons why your car may fail to start. The most common cause of starting problems usually has to do with either the battery, the starter, or a combination of both.
