Factory GM Alternators

The alternator is a motor that produces electricity. It is located in your vehicle's engine space, and without a functioning one, your car will lose power.

Why is an Alternator Important for My Car?

The alternator is powered by the motion of your serpentine belt. The belt turns a rotor on the alternator motor and spins a pair of electromagnets around a coil on the interior housing of the motor. The voltage created is delivered to the car battery, which charges while you drive. The alternator is also responsible for powering parts like your powered windows, water pump, or in some cases, the windshield wipers.

When to Replace Your Car's Alternator?

Alternators are used every time you drive. They can last the lifespan of your car but tend to lose efficiency after 100,000 miles. You may notice dimming interior dash lights, or a dead battery which will leave your car dead at start. If you experience troubles starting your car, have your alternator inspected by an expert. If your alternator is old and beginning to fail, replace immediately!
