Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the engine is cool before working on components.

2. Inspect and Repair Electrical Components

Sub-steps:
1. Visually inspect wiring harnesses and connectors for damage or melting.
2. Replace any damaged wiring or connectors using appropriate gauge wire and connectors.
3. Secure all wiring away from hot engine components using heat-resistant tape or sleeves.

3. Address Fluid Leaks

Sub-steps:
1. Identify the source of any leaks (e.g., oil pan, transmission seal).
2. Replace gaskets or seals as needed.
3. Refill any lost fluids to the appropriate levels (engine oil, coolant).

4. Inspect and Replace Overheating Components

Sub-steps:
1. Check the cooling system for leaks or blockages in hoses and radiator.
2. Replace any damaged hoses or a faulty thermostat.
3. Test the radiator fan operation; replace if non-functional.

5. Brake System Inspection

Sub-steps:
1. Inspect brake pads and rotors for excessive wear or burning.
2. Replace worn brake pads and resurface or replace rotors as necessary.
3. Ensure calipers are functioning properly and not sticking.
