Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical short circuits.

2. Check Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type of oil specified in the owner's manual.

3. Inspect for Fluid Leaks

Look under the vehicle for any puddles or drips.
Identify the type of fluid (oil, coolant, brake fluid) based on color and smell.
If a leak is found, repair or replace the affected components (e.g., oil filter, hoses).

4. Examine Brake System

Remove the wheel to inspect brake pads and rotors.
Check for signs of excessive wear or brake dust build-up.
Replace worn pads or rotors if necessary and ensure the brake fluid is at the correct level.

5. Inspect Electrical Wiring

Visually inspect wiring harnesses for melted or burnt insulation.
Repair or replace damaged wiring as needed to prevent further issues.
Secure any loose connections to ensure proper electrical flow.

6. Check Belts and Hoses

Inspect belts for signs of fraying, cracks, or glazing.
Check hoses for leaks, bulges, or wear.
Replace any damaged belts or hoses with OEM or equivalent parts.
