Solution

1. Preparation

Gather tools: socket set, ratchet, serpentine belt tool or wrench, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Disconnect Battery

Using a socket, disconnect the negative terminal of the battery to prevent electrical shorts.

3. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner. Use a serpentine belt tool or wrench to relieve tension on the belt.
While holding the tensioner, slide the belt off the pulleys, starting from the alternator or the furthest pulley from the tensioner.
Carefully release the tensioner back into its resting position.

4. Install the New Serpentine Belt

Refer to the serpentine belt routing diagram located on the engine bay or in the owner's manual.
Begin threading the new serpentine belt around the pulleys, ensuring it is correctly routed.
Use the serpentine belt tool or wrench to again relieve tension from the tensioner.
Slide the belt over the tensioner pulley last, and then release the tensioner to secure the belt in place.

5. Reconnect Battery

Reattach the negative terminal of the battery using the socket.

6. Final Checks

Start the engine and observe the belt in operation for proper alignment and tension.
Listen for any unusual noises or signs of misalignment.
