Solution

1. Preparation

Gather Tools and Parts:
- Tools: Socket set, screwdriver set, coolant pressure tester, OBD-II scanner
- Parts: New thermostat (if faulty), new radiator cap (if leaking), coolant (if low)
Safety Precautions: Disconnect the battery before starting work and allow the engine to cool down to prevent burns.

2. Replace Faulty Thermostat

Remove Thermostat Housing:
- Disconnect hoses attached to the thermostat housing.
- Remove the bolts securing the housing using the socket set.
Replace Thermostat:
- Remove the old thermostat and clean the mating surfaces.
- Install the new thermostat, ensuring proper orientation.
- Reattach the thermostat housing and torque bolts to manufacturer specifications (typically around 15-25 ft-lbs).

3. Inspect and Repair Cooling System

Check for Leaks:
- Use a coolant pressure tester to check for leaks in the system.
- Replace any faulty hoses, clamps, or the radiator as necessary.
Flush Cooling System:
- If the coolant is dirty, flush the cooling system using a cleaner designed for this purpose, then refill with fresh coolant.

4. Verify Cooling Fan Operation

Test Cooling Fans:
- Start the engine and allow it to reach operating temperature.
- Verify that cooling fans activate as the temperature rises. If not, replace the fan motor or check the relay/fuse.
