How to replace the Coolant Temperature Sensor on Chevrolet Cobalt?

Before replacing the Engine Coolant Temperature (ECT) Sensor turn OFF the ignition then drain coolant until its level falls below the ECT sensor. First disconnect the ECT sensor electrical connector before you slowly remove the sensor from its location. New or original sensor installation requires sealer Saturn P/N 21485278 or a material of equivalent quality on the threads when sealer is not present. Tighten the ECT sensor to 10 N.m (89 lb in) followed by electrical connector attachment. The last step involves adding new coolant to the engine system. Treat the coolant sensor with care to stop sensor damage which can impact fuel control system operation while ensuring you install proper application components and apply correct torque levels to prevent system damage.
