Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, wrenches, brake cleaner, rags.
Disconnect the battery to ensure safety during repairs.

2. Address Fluid Issues

Engine Oil:
- Check oil level; if low, top up with the manufacturer-recommended oil.
- If oil is burnt, consider an oil change.
Transmission Fluid:
- Check level and color; if burnt or low, replace with appropriate transmission fluid.
Coolant:
- Inspect for leaks; replace any damaged hoses or fittings and refill with the correct coolant.

3. Brake System Inspection

Remove Wheel: Use a jack to lift the vehicle and remove the wheel to access the brake components.
Inspect Brake Pads and Rotors:
- Replace worn brake pads and ensure rotors are not grooved or warped.
- Clean the brake components with brake cleaner.
Reassemble Wheel: Reinstall the wheel and torque the lug nuts to the manufacturer’s specification.

4. Engine Belt and Hose Replacement

Inspect Belts and Hoses:
- Replace any damaged or frayed belts and hoses. Ensure they are properly routed and tensioned.

5. Final Checks

Reconnect the battery and start the vehicle.
Allow it to reach normal operating temperature while monitoring for any smells or noises.
