OEM GM Alternators

Refine Results

An alternator is one of the most important parts of an electrical system. What do alternators do? For one, they charge car batteries. Secondly, they transfer power along a network of fuses, relays, and wiring to a car's many systems. In short, a battery starts a car, but an alternator keeps it running.

Unfortunately, even top-quality OEM alternators like the one in your GM vehicle can go bad. Unfortunately, signs of alternator problems are neither apparent nor conclusive. Other than an alternator warning light turning on, such symptoms include headlight flicker, a car radio that doesn't work right, a burning smell around your battery or alternator, engine whines, and a dead battery. The worst sign is electrical failure. It usually indicates complete alternator failure.

Worse yet, you can cause your alternator to go out yourself. Jump-starting your car wrong is one way. Overloading the alternator by installing incompatible accessories is another. If you think your alternator is bad, inspect and test its charging system. Replace your alternator if it's at issue. Otherwise, it's a good idea to change an alternator every 7 years or every 80,000 to 150,000 miles, whichever comes first. Refer to your owner's manual for more details.
