2. Inspect and Replace the Serpentine Belt

Tools Required: Socket set, belt tensioner tool, replacement serpentine belt.
Instructions:
1. Locate the serpentine belt routing diagram (usually found on a sticker under the hood).
2. Use the belt tensioner tool to relieve tension on the belt.
3. Carefully remove the old belt from the pulleys.
4. Inspect the pulleys for any signs of wear or damage.
5. Install the new serpentine belt following the routing diagram, ensuring it is seated properly on all pulleys.
6. Reapply tension using the belt tensioner tool.
