Solution

1. Preparation

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

2. Inspect and Clean Engine Components

Tools Required: Socket set, cleaning solvent, rags
Inspect the engine for oil leaks. Clean any areas around leaks with cleaning solvent to identify the source.
Check the condition of the wiring harness and connectors for signs of melting or damage.

3. Replace Damaged Components

Tools Required: Socket set, torque wrench
If any damaged components are found (e.g., oil hoses, wiring), replace them with OEM parts.
Ensure all connections are tight and secure. Torque any bolts to manufacturer specifications.

4. Brake Inspection

Tools Required: Jack, jack stands, wheel chocks, brake cleaner
Raise the vehicle and remove the wheels to access the brake components.
Inspect brake pads and rotors for excessive wear or overheating. Replace if necessary.
Clean any dust or debris from the brake components using brake cleaner.

5. Fluid Change

Tools Required: Oil filter wrench, drain pan, funnel
If low on oil or coolant, drain the old fluid and replace it with the appropriate OEM fluid.
Use a funnel to avoid spills and ensure proper filling levels.
