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.
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.
1. Coat the threads of the sensor with sealant GM P/N 12346004 (Canadian P/N 10953480) or equivalent.
Notice: Refer to Fastener Notice.
