Solution

1. Preparation

Tools Required: Safety gloves, safety goggles, OBD-II scanner, socket set, jack and jack stands.
Safely park the vehicle on a level surface and engage the parking brake. Allow the engine to cool if previously running.

2. Addressing Fluid Leaks

Inspect for Leaks: Identify and clean any leaking fluid. Common fluids include oil, coolant, or transmission fluid.
Replace Seals or Gaskets: If leaks are found, replace any damaged seals or gaskets as necessary. Use appropriate sealant and torque specifications.

3. Brake Inspection and Maintenance

Remove Wheel: Use a jack to lift the vehicle and remove the wheel to access the brake components.
Inspect Pads and Rotors: Check for wear on brake pads and rotors. Replace if they are worn down or overheated.
- Tools Required: Torque wrench for reinstallation.
- Torque Specs: Refer to the manufacturer specifications for torque settings when reinstalling the wheel.

4. Electrical System Repair

Inspect Wiring: Look for any damaged or exposed wires in the engine bay and repair as necessary. Use electrical tape or heat-shrink tubing to cover any exposed areas.
Replace Faulty Components: If any burnt fuses or connectors are found, replace them with new components.

5. Final Checks and Cleanup

Reassemble Components: Ensure all components are securely reattached, including any panels removed for inspection.
Clean Up: Wipe down any spilled fluids to prevent future odors and hazards.
