Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts while working on the engine.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Replace the Serpentine Belt

Inspect: Remove the engine cover (if applicable) and visually inspect the serpentine belt for cracks or wear.
Remove: Use a socket wrench to relieve tension on the tensioner pulley and slide the belt off.
Replace: Install the new serpentine belt, ensuring it follows the correct routing as per the vehicle's belt diagram.
Torque: Ensure the tensioner is properly adjusted to maintain belt tension.

3. Check and Replace Tensioner and Pulleys

Remove: Disconnect any components obstructing access to the tensioner and pulleys (if necessary).
Inspect: Check the tensioner and idler pulleys for bearing failure by spinning them by hand; replace if they feel rough or are noisy.
Replace: Use a socket set to remove the old tensioner and install the new one, tightening to manufacturer specifications.
Reassemble: Reattach any components removed for access, ensuring all connections are secure.
