OEM GM Belts

Refine Results

There's a belt under your GM hood for nearly every auto part that moves. What belts do is make everything run properly. They move more than just your crankshaft, too. In fact, there are almost as many types of belts as your vehicle has systems. Your serpentine belt is one example. It works alongside your drive belts. Together, they move power steering parts, alternator parts, and more. Compressor belts and fan belts, on the other hand, work with your serpentine belt to move heating and air conditioning parts. Your timing belt, also called a timing chain in some GM models, turns your camshaft. This helps your engine valves and engine pistons pump at the proper intervals. All the other original GM belts at work are too many to name.

How to Spot the Signs of Belt Failure

Is your car or truck not running well? Is it disabled? Its belts may be the problems. Signs of bad belts include looseness, squeaking, battery issues, trouble with interior lighting, and a misfiring or overheated engine, if not damage that's led to outright engine and systems failures. If you see such symptoms, change the affected belts. Otherwise, replace belts according to your mileage, how you drive, and in what conditions. It's helpful to consult your owner's manual for a maintenance schedule.
