Solution

1. Preparation

Tools Required: Socket set, ratchet, serpentine belt tool or a wrench, torque wrench, and a flathead screwdriver.
Ensure the vehicle is parked on a flat surface, and the engine is turned off with the keys removed.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Old Serpentine Belt

Locate the serpentine belt routing diagram, usually found on a sticker in the engine bay or in the owner's manual.
Use a serpentine belt tool or wrench to relieve tension on the tensioner pulley.
Slide the belt off the tensioner pulley and then carefully remove it from the other pulleys.
Inspect all pulleys for any damage or wear during removal.

3. Install the New Serpentine Belt

Refer to the serpentine belt routing diagram and position the new belt around the pulleys according to the diagram.
Ensure the belt is seated correctly in the grooves of each pulley.
Use the serpentine belt tool or wrench to rotate the tensioner pulley and slide the belt over the tensioner pulley last to ensure proper tension.

4. Final Checks

Recheck the routing to ensure proper installation.
Reconnect the negative battery terminal.
Start the engine and observe the belt in operation for any irregular noises or misalignment.
