WARNING: This page is about a different car, the 2003 Pontiac Grand Prix, 2003 Chevrolet Monte Carlo, 2003 Chevrolet Impala, 2003 Buick Regal, and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Replacement components must be the correct part number for the application. Components requiring the use of the thread locking compound, lubricants, corrosion inhibitors, or sealants are identified in the service procedure. Some replacement components may come with these coatings already applied. Do not use these coatings on components unless specified. These coatings can affect the final torque, which may affect the operation of the component. Use the correct torque specification when installing components in order to avoid damage.
Coat the ECT sensor threads with Thread Sealer (12346004) or the equivalent. Install the ECT sensor. Tighten the ECT sensor to specification. See TORQUE SPECIFICATIONS . Connect the ECT sensor electrical connector. Refill the engine coolant system. See COOLING SYSTEM BLEEDING under COOLING SYSTEM.
