Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, OBD-II scanner, flashlight.
Ensure the vehicle is parked on a level surface and the engine is off and cool before starting any work.

2. Inspect and Replace Worn Components

Serpentine Belt Inspection:
1. Open the hood and locate the serpentine belt.
2. Check for any cracks, fraying, or signs of melting.
3. If damaged, remove the belt using a socket set and replace it with a new one, ensuring proper alignment.
Brake System Inspection:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads for wear; replace if they are worn down to the indicator.
4. Check calipers for proper operation; replace if they are stuck.

3. Tire Inspection

Inspect the tires for any signs of damage or excessive wear.
If the tires are overheating, consider rotating or replacing them based on their condition.

4. Fluid Leak Inspection

Check for any fluid leaks that may have come into contact with hot engine parts.
Clean up any spills and replace any leaking components (e.g., hoses or gaskets).
