How to replace the Engine Coolant Temperature Sensor (ECT) on 2007 Cadillac CTS?

Engine replacement of the Engine Coolant Temperature Sensor (ECT) requires waiting until the engine temperature falls to prevent coolant drain and safety hazards. Start by disabling the engine power and then take off any protective materials covering the ECT sensor. First disconnect the ECT sensor electrical connector before removing the ECT sensor from its place. The new ECT sensor installation requires a 22 N.m (16 lb ft) torque when tightening. Secure the ECT sensor electrical connector before reattaching the sensor shielding. Check and fill your vehicle's cooling system when needed as the last step.
