What About My Alternator?
But your battery might not be the underlying reason your car won't start. It may also be a faulty alternator. In fact, the battery just supplies power to start your car. Once you're driving, the alternator generates all the electricity you need, and it keeps your battery charged.
The fix might be as simple as tightening your alternator belt. But it's also possible that it's time for a new alternator.
Our Cadillac Service Center can check your alternator, and adjust or replace it for you. We'll also check all your belts for wear and replace any that are worn. Worn belts don't work as well as they should and they're at risk of breaking. You sure don't want a belt to break when you're driving on the highway.
