Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before proceeding.

2. Remove the Serpentine Belt

Use a socket and ratchet to rotate the belt tensioner counterclockwise and relieve tension on the belt.
Carefully slide the belt off the pulleys, noting the routing for reinstallation.

3. Inspect and Replace Worn Components

Inspect the tensioner:
- Check for play or stiffness in the tensioner arm.
- If worn, remove the tensioner bolt and replace it with a new one.
Inspect pulleys:
- Rotate each pulley by hand to check for smooth operation.
- Replace any pulleys that show signs of binding or damage.

4. Install New Serpentine Belt

Refer to the belt routing diagram (usually found on a sticker in the engine bay) to ensure correct orientation.
Loop the new belt over the pulleys as per the routing diagram.
Rotate the tensioner again and slide the belt into place.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and observe the belt operation for any noise or slipping.
