3 Signs Your Chevy Requires an Alternator Repair

The alternator has a vital role to play in your Chevy, as it produces the electricity needed by all your car’s systems. In time, the alternator can develop problems and you’ll need to visit your Chevy dealership for an alternator repair. These are a few signs you may need a replacement alternator.

3 Signs You Need an Alternator Repair at Your Chevy Dealership

Grinding or Whining Noises

A healthy alternator doesn’t make any sound as it spins at high speed to produce electricity. If you hear whining or grinding noises from your engine compartment, you could have an alternator problem that needs fixing. Grinding noises are usually made by damaged alternator bearings, which reduce the alternator’s speed and decrease the electricity supply. We can replace the bearings, and the alternator will work at full speed again.

Whining noises could be due to a worn alternator belt, or the belt jamming on a stuck pulley as it moves at high speed. The alternator belt is made from toughened rubber but develops cracks or other imperfections as it ages. A damaged belt could also snap, and your Chevy will immediately lose its electricity supply and shut down. We’ll examine the belt and either repair or replace it depending on the extent of the damage.

Failing Accessories

Random electrical issues can potentially appear, then disappear and never return. Although they’re strange, they don’t present any harm to your vehicle or its systems. If you’re experiencing continual issues with accessories that suddenly stop, then start again, dim, then bright headlights, or any other unusual behavior, you could have a weakening alternator.

As an alternator ages, it slows down. The speed reduction is permanent and will continue to drop until the alternator is replaced. The reduction in the electricity supply will cause issues throughout the electrical system as the components can’t get enough power to work effectively. We’ll replace your alternator, and the electrical problems will disappear.

Dead Battery

As the battery gets older, the breakdown of the chemicals that enable it to store electricity reduces its electricity storage capacity. This can leave the battery with insufficient power reserves at full charge to start your engine. If your battery is less than three years old, the most likely cause of a dead battery is alternator failure.

Eventually, the alternator won’t be able to supply enough power for all the systems that demand it. This also affects the battery, as the alternator won’t fully recharge the battery as it should. The battery will continue to lose power that is replenished and will die. We’ll test your alternator and replace it if necessary. We may also need to replace your battery if it’s completely drained.
