Solution

1. Preparation

Gather Tools: Ensure you have an OBD-II scanner, wrenches, socket set, and safety gear (gloves, safety glasses).
Safety First: Disconnect the battery to prevent electrical shorts or shocks during inspection.

2. Address Fluid Leaks

Inspect Fluid Levels: Check all fluid levels including engine oil, coolant, brake fluid, and transmission fluid. Top off or replace as necessary.
Repair Leaks: If any leaks are found, identify their source and replace gaskets, seals, or hoses as needed.

3. Inspect and Replace Worn Components

Brake Inspection: Remove the wheel to access brake components. Inspect pads and rotors. Replace any that are worn or damaged.
- Tools: Jack, jack stands, lug wrench, brake cleaner, and brake pads/rotors if needed.
Replace Damaged Belts/Hoses: If any belts or hoses show signs of wear or damage, replace them.
- Tools: Socket set, belt tensioner tool if applicable.

4. Clean and Reassemble

Clean Engine Bay: Remove debris from the engine bay and clean up any spilled fluids. This helps prevent future overheating.
Reassemble Components: Reinstall any components removed during inspection. Ensure all fasteners are tightened to manufacturer specifications.

5. Final Checks

Reconnect Battery: Reconnect the battery and ensure all electrical connections are secure.
Test Drive: Conduct a short test drive to monitor for any unusual smells or noises.
