Original GM Belts

There are two main belts in your vehicle's engine. Known as drive belts, there is the timing belt, and the serpentine belt. Both play a role in the complete functionality of your engine parts. Here's how they work.

Your timing belt is designed to attach to the camshaft and crankshaft. A rubber belt with one smooth side, and one side with teeth that grips to the gears it can withstand high temperatures and long-term use. When your timing belt turns, it assists in the correct timing of the valves and pistons opening. Without the correct time, your engine will seize or misfire.

The serpentine belt runs on a system of pulleys. It is used to power the alternator, giving mechanical energy to run parts like the car battery, windshield wipers, car radio, powered windows, and other various electrical items.

Drive belts tend to last until the 100,000 mile mark. Some may go longer, depending on your environment and driving frequency. You should always visually inspect your belts for any fraying, cracks, or breaks. A thinning timing belt can lead to more engine problems than you wish to handle.

• Squealing or whining beneath the hood
• Abnormal rattling
• Engine sputtering
• Dead engine
