Does the serpentine belt affect the battery?
I know the serpentine belt is connected to many different parts of my car. But, does the serpentine belt affect the battery?
Answer provided by
The serpentine belt does affect the battery. The belt keeps the alternator spinning, and those rotations in turn power your:
- Steering system
- Electrical system
- Air conditioning
- Other mechanical components in your engine
One of the most important things your alternator does is recharge your battery while you’re driving. If you’ve got a worn-out serpentine belt, your alternator won’t spin as frequently and won’t have the power to do all of its jobs.
A faulty serpentine belt could cause a domino effect of issues for your engine, so if you think something is wrong with it, you should get it checked out right away.
