    Q:
    How to replace the engine coolant temperature sensors on Chevrolet Cruze? Posted by Customer
    A:
    There are two engine coolant temperature sensors, an upper one located in the coolant outlet housing on 1.4L models or in the thermostat housing on 1.8L models, and a lower one mounted in the lower right side of the radiator on both models. Begin by turning the ignition key to OFF and draining the cooling system. For the engine-mounted ECT sensor on 1.4L models, remove the charge air cooler outlet pipe, disconnect the electrical connector from the ECT sensor, which is situated in the coolant outlet housing or thermostat housing, pull out the retaining clip, and twist and pull the sensor from its bore. Installation is the reverse of removal, ensuring the retaining clip is fully seated, followed by refilling the cooling system. For the radiator-mounted ECT sensor, remove the front bumper cover, locate the sensor on the right side of the radiator, disconnect the sensor electrical connector, remove the retaining clip, and pull the sensor from the radiator. Again, installation is the reverse of removal, ensuring the retaining clip is fully seated, and then refill the cooling system.

    Q:
    How is the Coolant Temperature Sensor installed and replaced in the cooling system on Chevrolet Malibu? Posted by Customer
    A:
    The ECT sensor is installed in the water outlet at the left end of the cylinder head, with some models featuring a second sensor on the passenger's side of the radiator tank. Begin by draining the cooling system to a level below the ECT sensor. For 1.5L engines, remove the turbocharger ducting between the throttle body and charge air cooler. Disconnect the ECT electrical connector and pull the retaining clip to remove the sensor, ensuring to slide the locking tab out first. Inspect the O-ring and replace it if damaged, then reinstall by reversing the removal process and refill the cooling system. For models with a second ECT sensor in the radiator, loosen the right-front wheel lug nuts, raise and support the front of the vehicle on jackstands, and remove the wheel and inner fender splash shield. Locate the sensor in the side of the radiator tank, disconnect the electrical connector, and pull the retaining clip to remove the sensor. Again, inspect the O-ring for damage, replace if necessary, and reinstall while refilling the cooling system afterward.
