Solution

1. Preparation

Tools Required: Safety goggles, gloves, OBD-II scanner, flashlights.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during inspection.

2. Addressing Fluid Leaks

Sub-steps:
1. Inspect the oil pan, gaskets, and hoses for any oil leaks.
2. If oil is leaking, replace damaged gaskets or hoses as necessary.
3. Check coolant levels; if low, inspect the radiator and hoses for leaks and replace any damaged components.
4. Refill fluids to the correct levels as per manufacturer specifications.

3. Electrical Component Inspection

Sub-steps:
1. Carefully inspect wiring harnesses and connectors for damage or melting.
2. Replace any damaged wires or connectors with OEM parts.
3. Ensure all connections are secure and free from corrosion.

4. Exhaust System Check

Sub-steps:
1. Inspect the exhaust manifold and pipes for cracks or leaks.
2. Tighten any loose bolts and replace gaskets if needed.
3. If overheating is suspected, consider checking the catalytic converter for blockages.

5. Brake System Inspection

Sub-steps:
1. Remove the wheel and inspect brake pads and rotors for wear.
2. Replace pads if they are worn down to the minimum thickness.
3. Clean brake components and ensure proper lubrication of moving parts.
