2002 Cadillac DeVille Parts Questions & Experts Answers

• Q: How to replace the Coolant Temperature Sensor on 2002 Cadillac DeVille?

  A: Begin the Engine Coolant Temperature (ECT) Sensor replacement by first turning OFF the ignition and draining coolant until it falls below the sensor's position. Connectors from the ECT sensor harness must be disconnected while you remove the ECT sensor. Upload sealer GM P/N 1050805 or equivalent onto the ECT sensor threads before installing the new ECT sensor with a maximum torque of 20 N.m (15 lb ft). Next connect the ECT sensor harness connector before restocking the coolant system. Handle coolant sensors with caution since sensor damage will impact fuel system function while always ensuring replacement components match the vehicle specifications. The service procedure assesses which components need sealing materials including thread locking compound and lubricants and corrosion inhibitors and sealants; these components may already come with pre-applied coatings. You should only use these coatings when specifically directed because they will modify both torque values and component working conditions.
