Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working.

2. Access the Serpentine Belt

Raise the front of the vehicle using a jack and secure it with jack stands.
Remove any components obstructing access to the serpentine belt, such as the engine cover if applicable.

3. Remove the Old Serpentine Belt

Locate the belt tensioner (usually a spring-loaded pulley).
Use a ratchet and socket to rotate the tensioner counterclockwise to relieve tension on the belt.
Slide the belt off the pulleys while maintaining tension on the tensioner.
Carefully release the tensioner back to its resting position.

4. Install the New Serpentine Belt

Refer to the belt routing diagram (usually located on a sticker under the hood) to ensure correct installation.
Position the new serpentine belt around the pulleys as per the routing diagram.
Rotate the tensioner counterclockwise again and slide the belt over the tensioner pulley.
Release the tensioner to apply tension to the belt.

5. Reassemble and Test

Reinstall any components that were removed to access the belt.
Reconnect the battery.
Start the engine and observe for proper belt operation and listen for any unusual noises.
