Solution

1. Preparation

Tools Required: Safety glasses, gloves, flashlight, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the engine is cool. Disconnect the battery for safety before starting any repairs.

2. Inspect and Replace Serpentine Belt

Remove the Engine Cover (if applicable):
- Unscrew any fasteners holding the cover in place.
- Carefully lift the cover off and set it aside.
Inspect the Serpentine Belt:
- Look for cracks, fraying, or signs of burning.
- Check for proper tension and alignment on the pulleys.
Remove the Old Serpentine Belt:
- Use a wrench to relieve tension on the belt tensioner.
- Slide the belt off the pulleys and remove it.
Install New Serpentine Belt:
- Route the new belt according to the belt routing diagram located near the engine bay.
- Ensure it is properly seated on all pulleys and adjust the tensioner as needed.

3. Brake System Inspection and Service

Inspect Brake Components:
- Remove the wheel to access the brake assembly.
- Check brake pads for wear; replace if they are thin or worn unevenly.
- Inspect calipers for any signs of sticking or overheating.
Replace Brake Pads (if necessary):
- Remove the caliper bolts and lift the caliper off the rotor.
- Remove the old brake pads and clean the caliper bracket.
- Install new brake pads and reattach the caliper securely.
Reassemble Wheel and Test:
- Reinstall the wheel and lower the vehicle.
- Repeat with the other wheels if necessary.
