Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery before working on electrical components.

2. Inspect and Replace Serpentine Belt

Locate the serpentine belt and check for cracks, fraying, or glazing.
If damaged, use a socket set to relieve tension on the tensioner pulley and remove the belt.
Install a new serpentine belt, routing it according to the belt routing diagram in the engine compartment.
Ensure it is properly tensioned before reconnecting the battery.

3. Brake Inspection and Replacement

Inspect the brake pads and rotors for wear. Remove the wheel using a lug wrench.
If pads are worn down to the indicators, replace them with new ones. Remove the caliper using a socket set, and slide out the old pads.
Compress the caliper piston using a C-clamp, install new pads, and reassemble the caliper.
Ensure rotors are not warped; replace them if necessary.

4. Tire Inspection

Check all tires for signs of overheating (bubbles or cracks).
Look for foreign objects stuck in the tread.
Replace any damaged tires and ensure they are inflated to the recommended pressure.
