To remove and install the ECT sensor, follow the specific instructions for your engine model. It is important to allow the engine to cool before removing the sensor to avoid burns. Unplug the electrical connector, use a 12 point 22mm thin wall deep well socket to remove the sensor by turning it counterclockwise. Remove the sensor along with its sealing washer. When installing the sensor, use a new sealing washer and tighten it to 10 ft. lbs. (14 Nm).
