Solution

1. Preparation

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

2. Access the Serpentine Belt

Remove any engine covers if applicable using a socket and ratchet.
Locate the serpentine belt routing diagram, usually found on a sticker near the engine bay.

3. Remove the Old Serpentine Belt

Use a serpentine belt tool or wrench to relieve tension from the belt tensioner.
While holding the tensioner, slide the belt off the tensioner pulley.
Carefully release the tensioner back to its resting position.
Remove the belt from all pulleys following the routing diagram.

4. Install the New Serpentine Belt

Compare the old belt with the new belt to ensure proper length and width.
Begin routing the new belt according to the routing diagram, ensuring it sits properly in all pulleys.
Pull the tensioner back with the serpentine belt tool and slip the belt over the tensioner pulley last.
Ensure the belt is seated correctly in all grooves of the pulleys.

5. Final Checks

Reinstall any engine covers that were removed.
Reconnect the negative battery terminal.
Start the engine and observe the belt to ensure it runs smoothly without noise.
