Solution

1. Preparation

Tools Required: Socket set, serpentine belt tool or ratchet with a socket.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner and use the serpentine belt tool or ratchet to relieve tension on the belt.
Slide the belt off of the tensioner pulley first, then remove it from all other pulleys while noting the belt routing for reinstallation.
Inspect the tensioner and pulleys for any wear or damage that may need addressing.

3. Install the New Serpentine Belt

Reference the belt routing diagram (usually located on the radiator support or under the hood).
Begin routing the new serpentine belt around the pulleys according to the diagram.
Leave the tensioner pulley for last; ensure the belt is seated properly in all grooves.
Use the serpentine belt tool or ratchet to relieve tension on the tensioner again, and slide the belt over the tensioner pulley.
Release tension on the tensioner to secure the belt in place.

4. Final Checks

Ensure the belt is properly seated on each pulley.
Reconnect the negative battery terminal.
Start the engine and observe the belt in operation for any misalignment or noise.
