Solution

1. Preparation

Gather tools and parts needed:
- Tools Required: Socket set, wrench set, serpentine belt tool (or a ratchet with a socket), and a flashlight.
- Parts Required: New serpentine belt.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner. Use a serpentine belt tool or a wrench to relieve tension on the belt.
While holding the tensioner, slide the belt off one of the pulleys (typically the alternator or idler pulley).
Slowly release the tensioner back to its resting position.
Carefully remove the belt from all other pulleys, noting the routing path for the new belt.

3. Install the New Serpentine Belt

Refer to the belt routing diagram (usually found on a sticker under the hood) to ensure correct installation.
Begin routing the new belt around the pulleys according to the diagram.
Leave the tensioner pulley for last; pull the tensioner to apply tension while slipping the belt over the tensioner.
Ensure the belt is properly seated in all grooves and is aligned on all pulleys.

4. Final Steps

Reconnect the negative battery terminal.
Start the engine and observe the belt operation for any unusual noises or misalignment.
Turn the steering wheel fully to check for power steering assist and ensure all accessories are functioning.
