Removal procedure
Attention! To avoid serious injury, never remove the engine coolant temperature sensor (ECT) with a hot engine. Allow the engine to cool to ambient temperature before performing this procedure (below 50 degrees Celsius).
1. Disconnect the negative battery cable.
2. Remove the decorative engine cover. See Part 1C2, "The mechanical part of the engine is HFV6 3.2L.
Attention! To avoid serious injury, never remove the radiator filler cap when the engine is hot. Allow the engine to cool to ambient temperature before performing this procedure (below 50°C).
3. Allow the engine to cool down to ambient temperature (below 50°C) and slowly remove the radiator filler cap.
4. Drain approximately two liters of coolant into a suitable container.
5. Disconnect wiring harness connector (1) from ECT sensor (2).
Attention! Before removing, clean the area around the ECT sensor to prevent dirt from entering the engine.
6. Remove ECT sensor (1).
Note: If coolant leaks from the cylinder head when the sensor is removed, screw the sensor back into the cylinder head and drain more coolant from the coolant system.
Installation procedure
1. Install the ECT sensor.
Tighten
Tighten the engine coolant temperature sensor to 22 Nm (16 lb-ft).
2. Connect the ECT sensor connector.
3. Refill the cooling system. See Part 1D3, Engine Cooling HFV6 3.2L.
