To install:


NOTE
Apply a non-hardening sealer to the sensor threads prior to installation in order to prevent coolant leaks. Use P/N 1050805 or the equivalent

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.
