Solution

1. Preparation

Tools Required: Socket set, ratchet, serpentine belt tool (or a long handle wrench), safety gloves.
Ensure the engine is cool and disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Old Serpentine Belt

Locate the serpentine belt routing diagram, usually found on a sticker near the engine compartment.
Use the serpentine belt tool to relieve tension on the belt by rotating the tensioner pulley.
Carefully slide the belt off the pulleys, noting its routing as you remove it.

Check the tensioner and idler pulleys for wear. If they are worn or noisy, replace them.
Inspect the pulleys for any debris or damage, and clean them if necessary.
It is advisable to replace the tensioner if it shows signs of wear.

4. Install the New Serpentine Belt

Obtain a new serpentine belt that matches the manufacturer's specifications.
Route the new belt according to the serpentine belt diagram.
Use the serpentine belt tool to again relieve tension on the tensioner and slip the belt over the last pulley.

5. Final Checks

Ensure the belt is properly seated on all pulleys and not twisted.
Reconnect the negative battery terminal.
Start the engine and visually inspect the belt operation for correct alignment and tension.
