Solution

1. Preparation

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

2. Inspect and Repair Engine Issues

Inspect for Leaks:
- Check for oil, coolant, or transmission fluid leaks.
- Clean any spilled fluids and replace gaskets or seals as necessary.
Replace Worn Components:
- If any hoses or belts are damaged, replace them.
- Check the condition of the catalytic converter for signs of overheating or blockage.

3. Brake System Inspection

Remove Wheel:
- Use a jack to lift the vehicle and securely place it on jack stands.
- Remove the lug nuts using a socket set and take off the wheel.
Inspect Brake Components:
- Check brake pads and rotors for wear. Replace if pads are below 3mm thickness or rotors are warped.
- Ensure the caliper is functioning properly and not sticking.
Reassemble Wheel:
- Reinstall the wheel, hand-tighten lug nuts, lower the vehicle, and then torque the lug nuts to manufacturer specifications.

4. Electrical System Inspection

Check Wiring:
- Inspect all visible wiring for fraying or melting, especially around high-heat areas.
- Replace any damaged wiring or connectors.
Test Electrical Components:
- Ensure that all electrical components, such as fans and lights, are functioning properly.
