• Q: How to replace the Engine Coolant Temperature Sensor on 2008 Cadillac DTS?

  A: The first step to replace the Engine Coolant Temperature Sensor requires removing the fuel injector sight shield. You must drain the cooling system through the Vac-N-Fill or Static Fill procedure. Start by removing the engine harness electrical connector from the ECT sensor position before removing the sensor itself. Before installing the new ECT sensor apply GM P/N 12346004 (Canadian P/N 10953480) or equivalent sealant to threads then torque the sensor to 20 N.m (15 lb ft). Connect the ECT engine harness electrical connector to the ECT sensor afterward fill the cooling system with either Static Fill or Vac-N-Fill before reinstalling the fuel injector sight shield. Take all necessary precautions when handling the coolant sensor because its operation relies on fuel control and confirm the correct component part number followed by torque specifications to avoid failures.
