Solution

1. Preparation

Tools Required: Safety gloves, safety glasses, OBD-II scanner, basic socket set, brake cleaner.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery if working on electrical components.

2. Address Engine Overheating

Check Coolant Levels:
- Remove the coolant reservoir cap (only when the engine is cool).
- Top off with the appropriate coolant type if low (check owner's manual for specifications).
Inspect Radiator and Hoses:
- Visually examine the radiator for leaks or blockages.
- Check hoses for cracks or wear; replace any damaged hoses.
Thermostat Replacement:
- If the thermostat is suspected to be faulty, remove it and replace it with a new one, ensuring proper orientation.

3. Brake System Inspection

Remove Wheel:
- Use a jack to lift the vehicle and secure with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; replace if they are worn down to the wear indicator.
- Inspect the rotors for scoring or discoloration; replace if necessary.
Clean Brake Components:
- Use brake cleaner to clean the brake pads and rotors before reassembling.

4. Electrical System Inspection

Check Wiring and Connectors:
- Inspect all visible wiring for fraying or burnt areas.
- Repair or replace damaged wiring as necessary.
Inspect Fuses:
- Check the fuse box for blown fuses related to engine and electrical systems; replace as needed.
