How to replace the Coolant Temperature Sensor on 2005 Buick LeSabre?

Before replacing the Engine Coolant Temperature (ECT) Sensor turn off ignition then drain coolant until it sits below sensor height. You must disconnect the electrical connector and then gently remove the ECT sensor. Before installing the new ECT sensor apply GM P/N 9985253 sealer (or equivalent) to the sensor threads and verify that the replacement part matches the specific application requirements. Taking care with thread locking compounds and lubricants and corrosion inhibitors and sealants is essential because incorrect application will impact final torque and component operating performance. Secure the ECT sensor by torqueing it to 20 N.m (15 lb ft). Attach the ECT harness connector to the ECT sensor before refilling the vehicle's cooling system.
