- Use a flashlight to check for oil or coolant leaks around the engine and undercarriage.
- If leaks are found, clean the area and replace any damaged gaskets or seals.
Check Engine Oil:
- Remove the dipstick, wipe it clean, reinsert, and check the oil level.
- If low, add the appropriate grade oil (refer to owner's manual) and check for contamination.
Inspect the Brake System:
- Remove the wheel to access brake components.
- Inspect brake pads and rotors for excessive wear; replace if necessary with quality parts.

3. Electrical System Check

Examine Wiring:
- Inspect all visible wiring for signs of damage or melting.
- Repair or replace any damaged wiring with appropriate gauge wire.
Test Electrical Components:
- Use a multimeter to check the voltage of battery and alternator.
- Replace any failing components or fuses as needed.

4. Additional Checks

Inspect Belts and Hoses:
- Look for cracks, fraying, or wear on belts and hoses.
- Replace any damaged belts or hoses to prevent further issues.
