1. Preparation

Tools Required: Socket set, wrench set, OBD-II scanner, multimeter, flashlight, rags.
Allow the engine to cool down before working to prevent burns.
Disconnect the battery to avoid electrical hazards.

2. Inspect and Repair Leaks

Sub-steps:
- Clean the engine bay with degreaser to identify the exact source of the leak.
- Check for oil leaks around the oil filter and oil pan.
- Inspect the coolant hoses and radiator for leaks; replace any damaged hoses.
- If a leak is found, replace the affected component (e.g., oil filter, hose, or gasket).

3. Replace Worn Belts and Hoses

Sub-steps:
- Use a socket set to remove any components obstructing access to the belts and hoses.
- Inspect all belts for cracks or fraying; replace if necessary.
- Check hoses for softness or bulging; replace with OEM parts if damaged.
- Reassemble any components removed and ensure all fasteners are torqued to manufacturer specifications.

4. Electrical Inspection

Sub-steps:
- Visually inspect wiring harnesses for melted insulation or burnt wires.
- Use a multimeter to test for continuity in any suspect wiring.
- Repair or replace damaged wiring as required to prevent further issues.

5. Fill Fluids

Sub-steps:
- Ensure the engine oil and coolant are at their proper levels.
- Top off with manufacturer-recommended fluids if levels are low.
- Run the engine and monitor fluid levels, topping off as necessary.
