How to replace the Coolant Temperature Sensor on Buick Lucerne?

Start the ECT sensor replacement by draining the cooling system until the sensor position becomes visible. First disconnect the ECT sensor's engine harness electrical connector then remove the intake manifold cover before extracting the sensor. When installing a new ECT sensor use GM P/N 12346004 (Canadian P/N 10953480) sealant or equivalent while checking that all replacement parts have the correct application number. Thread locking compounds along with lubricants corrosion inhibitors and sealants require special caution during usage because improper application can impact torque values and component operational behavior. After torquing the sensor to 23 N.m (17 lb ft) reconnect the engine harness electrical connector to the ECT sensor and then refill the cooling system before reinstalling the intake manifold cover.
