What's that whining or grinding noise coming from my alternator?

A whining, grinding, or growling noise from the alternator usually points to worn internal bearings or a belt that's loose or slipping. The alternator spins constantly whenever the engine runs, so those bearings wear over time and start making noise before the part fully fails. If you're hearing it, bring your vehicle to General Automotive Servicenter in Gaithersburg for an inspection, catching it early can save you from a dead battery and a no-start down the road.

Do you replace the alternator and starter together?

Not necessarily, because the alternator and starter are two separate parts that fail independently. A bad alternator won't start your car reliably and a bad starter won't crank it, but a problem with one doesn't automatically mean the other needs replacing. The expert team at General Automotive Servicenter will test both, so you only replace the part that's actually failed instead of paying for work you don't need.

How long does an alternator replacement take?

Most alternator replacements can be completed the same day, though the exact time depends on your vehicle and where the alternator sits in the engine bay. Some are quick and easy to reach, while others take more labor to access. Our hours are Mon-Fri: 6:30 AM - 4:30 PM | Sat-Sun: Closed, and when you bring your car to General Automotive Servicenter we'll give you an honest time estimate up front so you can accordingly.
