The belt is driven by the crankshaft pulley, which is turned by the engine's rotation.
How to Inspect the Serpentine Belt
It's important to inspect the serpentine belt on a regular basis to ensure that it's in good condition. Here are some tips for inspecting the belt:
- Turn off the engine and wait for it to cool down completely.
- Open the hood and locate the serpentine belt. It should be a long, multi-ribbed belt that runs around the engine.
- Check the belt for any signs of wear or damage, such as cracks, fraying, or glazing.
- Check the tension of the belt by pressing down on it with your finger. It should have some give, but not too much.
