- Place the new thermostat in the housing, ensuring correct orientation.
- Reattach the housing and tighten bolts to manufacturer torque specifications.

4. Radiator Fan Inspection/Replacement

Inspect Fan Operation:
- Reconnect the battery and start the engine to check if fans activate at the appropriate temperature.
Replace Fan (if faulty):
- Remove the fan shroud and disconnect wiring.
- Unscrew the fan assembly and replace it with a new unit.
- Reconnect wiring and ensure proper fitment.

5. Water Pump Inspection/Replacement

Inspect Pump:
- Check for leaks around the water pump seal.
Replace Water Pump (if necessary):
