Solution

1. Preparation

Ensure the vehicle is parked on a flat, stable surface.
Disconnect the battery to prevent electrical shorts while working.
Gather all necessary tools and parts.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool, new serpentine belt.
Instructions:
1. Locate the serpentine belt routing diagram (often found on a sticker in the engine bay).
2. Use the belt tensioner tool to relieve tension on the belt.
3. Remove the old serpentine belt from the pulleys.
4. Inspect pulleys for wear; replace any that are damaged.
5. Install the new serpentine belt according to the routing diagram.
6. Ensure the belt is properly seated on all pulleys.

3. Inspect and Replace Tires

Tools Required: Tire pressure gauge, tire iron, jack, new tires (if needed).
Instructions:
1. Check the tire pressure and adjust to manufacturer specifications.
2. Inspect the sidewalls and tread for signs of damage or excessive wear.
3. If any tires are damaged, use a jack to lift the vehicle and remove the affected tire.
4. Install new tires, ensuring they are properly balanced and torqued to manufacturer specifications.

4. Check Brake System

Tools Required: Jack stands, socket set, new brake pads (if needed).
Instructions:
1. Lift the vehicle and securely place it on jack stands.
2. Remove the wheel to access the brake system.
3. Inspect brake pads for wear; replace if they are thin or uneven.
4. Check calipers for binding; lubricate slide pins if necessary.
5. Reinstall the wheel and lower the vehicle.
