Lucerne V6-3.8L VIN 2 (2006)
INSTALLATION PROCEDURE
IMPORTANT: Care must be taken when handling engine coolant temperature sensor. Damage to the engine coolant temperature sensor will effect
proper operation of the fuel injection system.
1. Coat the threads of the sensor with sealant GM P/N 12346004 (Canadian P/N 10953480) or equivalent.
IMPORTANT: Replacement components must be the correct part number for the application. Components requiring the use of 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 effect the final torque, which may affect the
operation of the component. Use the correct torque specifications when installing components in order to avoid damage.
2. Install the ECT sensor.
NOTE: Refer to Fastener Notice.
Tighten the sensor to 23 N.m (17 lb ft).
