Solution

1. Preparation

Tools Required: Socket set, ratchet, serpentine belt tool, torque wrench, flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electric shock.

2. Remove the Old Serpentine Belt

Locate the serpentine belt routing diagram, typically found on a sticker in the engine bay.
Use a serpentine belt tool or a ratchet with a socket to relieve tension on the belt by rotating the tensioner pulley.
Carefully remove the belt from the pulleys, noting the routing for installation of the new belt.

3. Inspect Components

Inspect all pulleys and the tensioner for damage or excessive wear.
Replace any damaged components before installing the new belt.

4. Install the New Serpentine Belt

Refer to the serpentine belt routing diagram to ensure correct installation.
Position the new belt over the pulleys, leaving the tensioner pulley last.
Use the serpentine belt tool to rotate the tensioner again, allowing the belt to slip over the tensioner pulley.

5. Final Checks

Ensure the belt is properly seated in all grooves of the pulleys.
Reconnect the negative battery terminal.
Start the engine and observe the belt operation for any unusual sounds or misalignment.
