Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off and cooled down.
Disconnect the battery for safety.

2. Inspect and Repair Oil Leaks

Sub-steps:
1. Visually inspect engine components for oil leaks, particularly around gaskets and seals.
2. Clean any spilled oil using degreaser and a cloth.
3. Replace any worn gaskets, seals, or components as necessary.
4. Refill any lost oil to the correct level using the manufacturer-recommended oil type.

3. Brake System Inspection and Repair

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake pads and rotors for wear; replace pads if they are worn down to the indicators.
3. Check brake fluid levels and top off if necessary; replace fluid if it appears contaminated.
4. Reassemble the wheel and ensure lug nuts are torqued to specification.

4. Cooling System Check

Sub-steps:
1. Inspect radiator hoses and connections for leaks or damage.
2. Check coolant levels in the reservoir; top off with manufacturer-recommended coolant if low.
3. Test the thermostat and water pump for proper operation.
4. Replace any defective components as identified during inspection.
