Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is off and cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Brake Components

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, new brake pads, and rotors if needed.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.
Inspect brake pads and rotors for signs of wear; replace if necessary.
- If pads are worn down to the metal or rotors are scored, replace them.
Clean the brake components with brake cleaner before reassembly.
Reinstall the wheel and lower the vehicle.

3. Check and Repair Fluid Leaks

Inspect the engine and transmission for any fluid leaks.
If oil or coolant is leaking, identify the source (e.g., gasket, hose, or seal).
Replace any damaged components and top off fluids as needed.

4. Electrical Inspection

Inspect wiring harnesses and connectors in the engine bay for burn marks or melting.
Replace any damaged wires or connectors found.

5. Verify Engine Oil Level

Check the engine oil level using the dipstick.
If the oil is low, add the appropriate type of oil as specified in the owner's manual.
If the oil appears burnt or contaminated, perform an oil change.
