Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, brake cleaner, multimeter, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using a lug wrench.
- Check the thickness of the brake pads; replace if they are below 3mm.
- Inspect the rotors for scoring or warping; replace if necessary.
Replace Brake Pads:
- Remove the caliper using a socket set.
- Remove the old brake pads and clean the caliper bracket with brake cleaner.
- Install new brake pads ensuring they are seated properly.
- Reinstall the caliper and torque to specification (typically 20-30 ft-lbs).

3. Address Engine Issues

Inspect and Replace Belts and Hoses:
- Check for cracks or wear on the serpentine belt; replace if damaged.
- Inspect hoses for leaks or signs of deterioration; replace as necessary.
Coolant System Check:
- Ensure the coolant level is adequate; add coolant if low.
- Look for leaks around the radiator and hoses.

4. Electrical System Inspection

Check Wiring:
- Inspect wiring harnesses for signs of wear or overheating.
- Use a multimeter to test for continuity and check any fuses.

5. Final Assembly and Testing

Reconnect the battery.
Reinstall the wheel and torque lug nuts to specification (usually 80-100 ft-lbs).
Start the engine and visually inspect for any further leaks or smoke.
