How to Replace a Coolant Temperature Sensor Without Damaging the Fuel Control System on Buick Regal?

Beginning engine coolant temperature sensor (ECT) replacement requires a first step to turn OFF the ignition while draining part of the cooling system. Remove the ECT sensor after disconnecting its electrical connector with caution since sensor damage could impact the fuel control system. The threads of the new sensor require a GM P/N United States 12346004 or Canada 10953480 sealer or equivalent before installation. After ensuring the parts match the application you must use, continue the installation process. Tighten the ECT sensor with torque to 20 N.m (15 lb ft). The installation process ends when both the ECT sensor electrical connector is connected and the cooling system is filled.
