Solution

1. Preparation

Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the negative battery terminal to prevent any electrical shorts.
Gather tools and parts needed for the replacement.

2. Remove the Serpentine Belt

Tools Required:
- 3/8-inch drive ratchet
- Serpentine belt tool or a wrench
Locate the serpentine belt tensioner. Use the serpentine belt tool or ratchet to rotate the tensioner counterclockwise to relieve tension on the belt.
Carefully slide the belt off the pulleys, starting with the alternator or power steering pump for easier access.
Note the belt routing for reinstallation; it may be helpful to take a photo.

3. Install the New Serpentine Belt

Tools Required: None additional.
Position the new serpentine belt according to the routing diagram typically found on a sticker under the hood or in the owner's manual.
Start by placing the belt around the crankshaft pulley and then work it around the other pulleys while ensuring it is seated correctly in the grooves.
Rotate the tensioner again counterclockwise and slide the belt over the tensioner pulley.

4. Final Inspection and Reconnection

Double-check the belt routing to ensure it is properly aligned on all pulleys.
Reconnect the negative battery terminal.
Start the engine and observe the belt operation for any unusual noise or misalignment.
