Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is off and cool.

2. Inspect Engine Bay

Open the hood and visually inspect for any fluid leaks, particularly oil or coolant.
Look for any signs of burnt plastic or electrical components.
If oil leaks are present, clean the area to identify the source.

3. Check Electrical Components

Inspect all wiring harnesses and connectors for damage or corrosion.
Use a multimeter to test the voltage at various connectors to ensure proper electrical function.
Replace any damaged wiring or connectors as necessary.

4. Brake System Inspection

Remove the wheel to access the brake system.
Inspect brake pads for excessive wear and replace if necessary.
Check the brake calipers for sticking or overheating and replace if needed.

5. Cooling System Check

Verify coolant levels in the reservoir and radiator; top off with the appropriate coolant if low.
Inspect hoses and connections for leaks; replace any damaged hoses.
If overheating persists, consider flushing the cooling system and replacing the thermostat.

6. Serpentine Belt Inspection

Visually inspect the serpentine belt for cracks, fraying, or glazing.
If the belt is damaged, remove it and replace it with a new one, ensuring proper tension.
