Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, coolant pressure tester, flashlight.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting any work.

2. Addressing Oil Leaks

Locate the source of the leak:
- Use a flashlight to inspect for oil leaks around the engine block, oil pan, and gaskets.
Replace gaskets or seals as needed:
- Remove the components obstructing access to the leaking area (e.g., underbody shields).
- Clean the affected surfaces and apply new gasket material or replace the seal.
- Reassemble components and ensure all bolts are torqued to manufacturer specifications.

3. Cooling System Inspection

Check for leaks:
- Use a coolant pressure tester to pressurize the cooling system and identify leaks.
Replace any damaged hoses or clamps:
- Remove and replace damaged or worn hoses, ensuring proper fittings.
- Tighten hose clamps to secure the connections.
Flush the cooling system if necessary:
- Drain old coolant, flush the system with clean water, and refill with the appropriate coolant mixture.

4. Electrical Inspection

Inspect wiring harnesses:
- Visually check all wiring for signs of fraying, melting, or short circuits.
- Use a multimeter to check for continuity in suspicious wiring.
Replace any damaged wire:
- Cut out damaged sections and splice in new wire, ensuring proper insulation.
