• Q: How to replace the Coolant Temperature Sensor on 2004 Buick Regal?

  A: A partial drain of the cooling system constitutes the first step when replacing the engine coolant temperature (ECT) sensor. Start by removing the Thermostat Housing followed by disconnecting the ect sensor electrical connector before proceeded with ect sensor removal. When installing the coolant sensor handle it with precision to prevent any damage that might impact the fuel control system performance. Always replace components with parts that correspond to the specific application requirements while using thread locking compound and lubricants and corrosion inhibitors and sealants according to specifications. Use the sealer gm p/n 12346004 (Canadian P/N 10953480) or equivalent to coat the threads before you install and torque the ect sensor to 20 n.m (15 lb ft). Filling of the cooling system should occur after reconnecting the ect sensor electrical connector and reattaching the Thermostat Housing.
