Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, coolant pressure tester, flashlight
Ensure the engine is cool before beginning any inspection.
Disconnect the battery to avoid electrical shorts while inspecting.

2. Inspect Fluid Leaks

Sub-steps:
1. Visually inspect the ground where the vehicle was parked for fluid spots.
2. Check the engine oil level and condition; add oil if low.
3. Inspect the coolant reservoir and radiator for leaks; top off coolant if needed.
4. If any leaks are found, replace the faulty gaskets, seals, or hoses.

3. Inspect Belts and Hoses

Sub-steps:
1. Remove any covers that obstruct access to the serpentine belt and hoses.
2. Check the condition of the serpentine belt for cracks or fraying; replace if necessary.
3. Inspect all hoses for bulges, cracks, or leaks; replace any damaged hoses.

4. Examine Brake Components

Sub-steps:
1. Lift the vehicle and remove the wheels to access the brake components.
2. Inspect brake pads for wear and the rotors for overheating signs (blue color).
3. Replace any worn-out brake pads or rotors as needed.
