Clean Affected Areas:
- Use cleaning rags to wipe any visible oil or coolant spills to prevent confusion during future inspections.

3. Replace Damaged Components

If Leaks are Found:
- Identify the specific leaking component (e.g., hoses, gaskets).
- Remove the defective part using the socket set.
- Install the new part ensuring proper alignment and secure all connections.
If Belts are Worn:
- Loosen the tensioner and remove the old belt.
- Install a new belt according to the manufacturer’s specifications.

4. Refill Fluids

Engine Oil:
