Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Access the Serpentine Belt

Remove any engine covers if necessary using a socket set.
Locate the serpentine belt routing diagram, usually found on a sticker in the engine compartment or in the owner’s manual.

3. Release Tension from the Serpentine Belt

Use a wrench or ratchet to turn the belt tensioner counterclockwise to relieve tension on the serpentine belt.
While holding the tensioner, slide the belt off one of the pulleys (preferably the alternator or idler pulley).

4. Remove the Old Serpentine Belt

Carefully release the tensioner and remove the old serpentine belt from all pulleys.
Take note of the belt routing for installation of the new belt.

5. Install the New Serpentine Belt

Route the new serpentine belt according to the routing diagram.
Ensure the belt is seated properly in the grooves of the pulleys.
Use the tensioner tool to apply tension and slide the belt onto the last pulley.

6. Final Checks

Double-check the belt alignment and ensure it is securely in place on all pulleys.
Reconnect the negative battery terminal.
