Coolant temperature sensor (Chevrolet Captiva 1)

Removal procedure

Caution: To avoid serious injury, never remove the engine coolant temperature (ECT) sensor when the engine is hot. 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, "Engine Mechanical - HFV6 3.2L".

Caution! To avoid serious injury, never remove the radiator filler cap when the engine is hot. Allow the engine to cool to ambient temperature (below 50°C) before performing this procedure.

3. Allow the engine to cool 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 the wiring harness connector (1) from the ECT sensor (2).

Caution: Before removing, clean the area around the ECT sensor to prevent dirt from getting into the engine.

6. Remove the 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 N·m (16 lb-ft).

2. Connect the ECT sensor connector.

3. Fill the cooling system. See Part 1D3, Cooling of the HFV6 3.2L engine.
