Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, flashlight, gloves, safety glasses.
Safety Warning: Ensure the vehicle is parked on a flat surface, and the engine is cool before beginning work.

2. Inspect and Replace Worn Belts

Inspect Belts:
- Remove any engine covers if necessary.
- Examine the drive belts for signs of wear (cracks, fraying).
Replace Belts:
- If wear is present, loosen the tensioner using a socket and ratchet.
- Remove the old belt by routing it off the pulleys.
- Install the new belt according to the manufacturer's routing diagram.
- Tighten the tensioner to the specified torque (usually around 18-22 Nm).

3. Check and Fix Fluid Leaks

Inspect for Leaks:
- Use a flashlight to look for any signs of fluid around the engine.
Repair Leaks:
- If coolant or oil leaks are found, identify the source (e.g., hoses, gaskets).
- Replace any damaged hoses or gaskets as necessary. Clean the area after repairs to ensure no further leaks.

4. Monitor Engine Temperature

Test Drive:
- After repairs, take the vehicle for a short test drive.
- Monitor the temperature gauge to ensure it remains within normal operating range.
