Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.
Wear safety gloves and goggles.

2. Inspect and Repair Engine Components

Sub-steps:
1. Open the hood and inspect all wiring harnesses and plastic components for signs of burning or melting.
2. If damage is found, replace any burnt wiring or connectors with OEM parts.
3. Clean any oil or fluid spills around the engine with appropriate degreasers.

3. Brake System Inspection and Repair

Sub-steps:
1. Remove the wheel on the affected brake assembly using a socket set.
2. Inspect the brake pads for wear; if they are worn down to the backing plate, replace them.
3. Check the brake rotors for scoring or excessive heat discoloration; replace if necessary.
4. Reassemble the wheel and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Address Engine Overheating Issues

Sub-steps:
1. Check coolant levels in the reservoir; if low, refill with the correct type of coolant.
2. Inspect for leaks in the radiator or hoses; replace any damaged components.
3. Ensure the thermostat is functioning correctly; replace if it is stuck closed.
