Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Components

Visual Inspection
- Check for burnt wires or loose connections. Repair or replace any damaged wiring.
- Inspect the engine oil and coolant for contamination. Change if necessary.
Fluid Replacement
- If coolant is low, refill with the appropriate type (Ford uses a specific blend).
- For engine oil, drain the old oil, replace the oil filter, and refill with the recommended oil type and quantity.

3. Brake System Inspection

Remove Wheel
- Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel.
Inspect Brake Components
- Check brake pads for wear; replace if they are below the minimum thickness.
- Inspect calipers for proper function; ensure they are not sticking.

4. Electrical System Repair

Wiring Repair
- Repair any damaged electrical connections or wires. Use heat-shrink tubing for insulation.
- Secure any loose wiring to prevent contact with hot engine components.

5. Reassemble and Test

Reinstall any components removed during inspection and repairs.
Reconnect the battery and start the engine, monitoring for any lingering smells or issues.
