OEM GM Alternators

Your alternator is responsible for powering various parts of your GM vehicle's electric system. Simply put, it helps turn chemical energy into electrical energy so that your battery can charge. The headlights, dashboard lights, heated seats, and windshield wipers are only some of the parts that are powered by the alternator.

When Do I Need to Change My Alternator?

Depending on your make and model, it's highly recommended to replace the alternator every 100,000 miles or about every seven years. The signs of a failing alternator are easy to spot. Some of these signs include:

  • Headlights are very dim or bright
  • A dead battery
  • Slow functioning or accessories that don't work
  • Trouble starting your car, truck, or SUV
  • The smell of burning rubber
  • Warning light pops up on the dash
