What Does an Alternator Do?

Close-Up of Alternator

If you’re new to car maintenance, you may be wondering, “What does an alternator do?” Our service department is happy to teach you what an alternator is and does under the hood of your Chevrolet. The alternator sends power to the car’s electrical system while the engine is on. The battery and the alternator work together as a generator using the gas engine as a source of energy. Choose OEM parts to ensure you’re equipping your vehicle with quality components that will maximize performance. Contact us for more information on what an alternator does and how much it costs to replace an alternator.


What Are the Signs of a Bad Alternator?

Our service team will install it for you, and can even give you an estimate for an oil change while you’re here. Our service department is located in Jacksonville near Camp Lejeune. If you notice any of these signs, you may be due for a new alternator:

  • Unable to start your vehicle
  • Screeching or whining noise when you try to start your vehicle

How Long Does an Alternator Last?

Alternators last between 80,000 and 150,000 miles, or about seven years. Some factors that decrease an alternator’s lifespan include:

  • The quality of the alternator
  • Your driving conditions and habits
