Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, tire pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Inspect and Replace Worn Belts or Hoses

Sub-steps:
1. Open the hood and visually inspect all belts for signs of wear. Focus on the serpentine belt and any accessory drive belts.
2. Check hoses for any cracks, leaks, or signs of melting.
3. If any belt is found to be damaged, use the socket set to loosen the tensioner and remove the belt. Replace it with a new belt following the manufacturer's specifications.
4. For damaged hoses, loosen the clamps and remove the hose. Install new hoses, ensuring they are secured tightly.

3. Brake System Inspection and Repair

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for thickness; replace if below the manufacturer’s recommended minimum.
3. Check the rotors for signs of overheating or warping. Replace if necessary.
4. Reassemble the wheel and torque the lug nuts to the manufacturer’s specifications.

4. Tire Inspection and Adjustment

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate to the recommended PSI found in the owner's manual or door jamb.
2. Inspect for any signs of uneven wear that may indicate misalignment or suspension issues. Rotate or replace tires as needed.
