Installation Procedure
WARNING: This page is about a different car, the 2005 GMC Canyon and 2005 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.
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.
- If installing the original sensor or a new sensor without sealant, apply thread sealer GM P/N 12346004 (Canadian P/N 10953480) or equivalent.
- Using the J 45861
