Solution

1. Preparation

Tools Required: Socket set, ratchet, serpentine belt tool or wrench, torque wrench.
Safety Warnings: Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner. Use the serpentine belt tool or a wrench to relieve tension on the belt.
While holding the tensioner in the released position, carefully slide the belt off the pulleys, starting with the easiest one to access.
Once the belt is free, slowly release the tensioner back to its resting position.

3. Inspect Components

Before installing the new belt, visually inspect all pulleys for wear and ensure they rotate freely.
Check the tensioner for proper operation; it should not be worn out or loose.

4. Install the New Serpentine Belt

Refer to the serpentine belt routing diagram, usually found on a sticker under the hood or in the owner's manual.
Route the new belt around the pulleys according to the diagram, ensuring it sits properly in the grooves.
Use the serpentine belt tool to pull the tensioner back again and slip the belt over the last pulley.
Carefully release the tensioner so that it applies tension to the new belt.

5. Final Checks

Ensure the belt is aligned properly on all pulleys and is not twisted.
Reconnect the negative battery terminal.
