Solution

1. Preparation

Tools Required: Safety gloves, safety goggles, OBD-II scanner, flashlight
Ensure the vehicle is parked on a level surface and the engine is off and cool.

2. Inspect and Clean

Sub-steps:
1. Open the hood and visually inspect the engine bay for any obvious signs of burnt oil or coolant leaks.
2. If any leaks are found, identify the source and clean the area with a degreaser.
3. Check the condition of wiring harnesses, looking for melted insulation or burnt wires. Replace any damaged wiring.
Safety Warning: Allow the engine to cool completely before inspecting to avoid burns.

3. Fluid Replacement

Sub-steps:
1. If oil or coolant levels are low, top them up with the appropriate fluids (engine oil: SAE 5W-30, coolant: recommended Ford Motorcraft Premium).
2. If either fluid is contaminated, drain and replace them according to manufacturer specifications.
3. Recheck for leaks after refilling.

4. Electrical Check

Sub-steps:
1. Using a multimeter, check the voltage at various electrical connections for proper operation.
2. Inspect the fuse box for any blown fuses and replace as necessary.
3. Ensure all ground connections are secure and free from corrosion.
