Original GM Alternators

What is an Alternator?

The alternator is a part of the charging system in your GM car, truck, or SUV. Its purpose is to turn mechanical energy into electricity. Simply put, alternators generate current.

But what exactly does the alternator do? For starters, it charges your battery so that it can run other electrical systems in your vehicle. These systems include the lights on your dash, the radio, power windows and windshield wipers.

When Do I Need to Replace My Alternator?

Like other auto parts, your alternator can fail. Failure can be due to damaged parts, a poor jump-start, or age. There are other signs that your alternator may be going bad, which include flickering headlights, a burning smell, or a dead car battery. Most owner's manuals recommend replacing the alternator every seven years or every 80,000 to 150,000 miles.
