Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical shorts.
Ensure the vehicle is on a flat surface and securely raise it if necessary using jack stands.

2. Access the Serpentine Belt

Locate the serpentine belt routing diagram under the hood or in the owner's manual.
Remove any components obstructing access to the belt, such as the engine cover, if applicable.
Use a socket wrench to relieve tension from the serpentine belt tensioner.

3. Remove the Old Serpentine Belt

Carefully slide the belt off the pulleys, noting its routing for reinstallation.
Inspect the tensioner and pulleys for wear or damage; replace if necessary.

4. Install the New Serpentine Belt

Route the new serpentine belt according to the routing diagram.
Ensure that the belt is seated properly in the grooves of each pulley.
Use the socket wrench to pull the tensioner back and slide the belt into place.

5. Final Checks

Reinstall any components that were removed for access.
Reconnect the negative battery terminal.
Start the engine and visually inspect the belt operation for proper alignment and tension.
