Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench.
Safety Warnings: Disconnect the battery before working on the engine components. Allow the engine to cool before inspection.

2. Inspect and Replace the Serpentine Belt

Remove the Engine Cover (if applicable):
- Use a socket set to remove any bolts securing the engine cover.
Release Tension on the Belt:
- Locate the tensioner pulley and use a wrench to rotate it counterclockwise to relieve tension on the belt.
Remove the Old Belt:
- Take the belt off all pulleys and note the routing for the new belt installation.
Install the New Belt:
- Route the new serpentine belt according to the belt routing diagram (usually found on a sticker under the hood).
Reapply Tension:
- Rotate the tensioner pulley again to allow the belt to fit snugly around the pulleys and release it to apply tension.

3. Inspect and Replace Worn Pulleys

Check Pulley Condition:
- Spin each pulley by hand to check for roughness or play.
Replace Any Faulty Pulleys:
- If any pulleys are worn or damaged, remove them using the appropriate socket and replace them with new ones.
- Torque the new pulleys to the manufacturer's specifications.

4. Reassemble Components

Reinstall Engine Cover (if removed):
- Secure the engine cover back in place using the previously removed bolts.
