Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Inspect and Replace Belts

Inspection:
- Visually inspect all drive belts for cracks, fraying, or glazing.
- Check for proper tension; a loose belt can slip and generate heat.
Replacement (if necessary):
- Loosen the tensioner bolt using a socket wrench.
- Remove the old belt and replace it with a new one, ensuring it is properly aligned.
- Tighten the tensioner bolt to the manufacturer's specifications.

3. Examine Tires

Inspection:
- Check tire pressure and inflate to recommended levels if low.
- Inspect tread depth and sidewall for any signs of damage or excessive wear.
Replacement (if necessary):
- If tires are worn or damaged, remove the wheel using a lug wrench.
- Install new tires, ensuring they are properly balanced and aligned.

4. Brake System Inspection

Inspection:
- Remove the wheel to access brake components.
- Inspect brake pads for wear; replace if they are below the minimum thickness.
- Check for signs of overheating on the rotors.
Replacement (if necessary):
- Remove caliper bolts and slide the caliper off the rotor.
- Replace worn brake pads and reassemble the caliper, ensuring all bolts are torqued to specifications.
