- Reinsert and pull out to check oil level; add oil if low.
- If oil smells burnt, consider an oil change, including a new filter.
Inspect for Leaks:
- Check gaskets, seals, and hoses for signs of oil or coolant leaks.
- Replace any damaged gaskets or hoses using appropriate seals and torque specifications.

3. Brake System Inspection

Inspect Brake Pads and Rotors:
- Remove the wheel to access the brake components.
- Check the thickness of the brake pads; replace if worn below the manufacturer’s specifications.
- Inspect rotors for warping or glazing; replace if necessary.

4. Electrical Inspection

Examine Wiring:
- Inspect wiring harnesses and connections for damage or signs of overheating.
- Repair or replace damaged wiring and secure any loose connections.
