Solution

1. Preparation

Gather tools: socket set, ratchet, serpentine belt tool (or a wrench), and a flashlight.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery cable to prevent electrical shorts.

2. Remove the Old Serpentine Belt

Use the serpentine belt tool to relieve tension on the belt by rotating the tensioner pulley counterclockwise.
While holding the tensioner, slide the belt off one of the pulleys (preferably the alternator or power steering pulley).
Carefully release the tensioner back to its resting position.
Remove the belt from all pulleys, taking note of the routing for installation of the new belt.

3. Inspect Components

Check the idler pulley and tensioner for wear; replace if necessary.
Clean the pulleys with a clean cloth to remove any debris or contaminants.

4. Install the New Serpentine Belt

Refer to the belt routing diagram, usually found on the engine bay or in the owner's manual.
Begin threading the new belt over the pulleys, making sure to follow the correct routing.
Use the serpentine belt tool again to rotate the tensioner and slide the belt over the last pulley.
Ensure the belt is seated properly on all pulleys.

5. Reconnect Battery and Test

Reconnect the negative battery cable.
Start the engine and observe the belt in operation. Check for proper alignment and listen for any unusual noises.
