Solution

1. Preparation

Tools Required: Safety goggles, gloves, flashlight, OBD-II scanner.
Safety Warnings: Disconnect the battery before working on electrical components. Allow the engine to cool before inspection.

2. Inspect Engine Components

Sub-steps:
1. Open the hood and visually inspect the engine bay.
2. Look for any burnt or melted plastic components, especially near the belts.
3. Check wiring harnesses for damage or signs of overheating.

3. Check Drive Belts

Sub-steps:
1. Locate the serpentine belt and inspect it for cracks, fraying, or shiny spots indicating wear.
2. If damaged, use a wrench to relieve tension on the belt tensioner and remove the old belt.
3. Install a new belt, ensuring it follows the correct routing diagram (usually found on a sticker in the engine bay).

4. Address Fluid Leaks

Sub-steps:
1. Clean any visible fluid on the engine and surrounding areas.
2. Start the engine and observe for leaks while monitoring the engine for abnormal sounds.
3. If a leak is detected, identify the source (e.g., oil pan, transmission, coolant) and replace the necessary gaskets or seals.

5. Inspect Tires

Sub-steps:
1. Check tire pressure and ensure it is within the manufacturer’s specifications.
2. Inspect for uneven wear patterns or foreign objects lodged in the tread.
3. Rotate or replace tires as necessary, ensuring proper alignment.
