CAUTION  Mechanical over-tightening can distort the threads or damage the filter head.

Apply a light film of lubricating oil to the coolant filter gasket sealing surface before installing the coolant filter.

Install the filter as specified by the manufacturer.

CAUTION  Severe engine damage will result if the shutoff valve is left closed.

After the filter has been changed, open the shutoff valve and install the radiator pressure cap.

Operate the engine until the coolant temperature is above 82°C [180°F], and check for coolant leaks.

After the air has been purged from the system and a minimum of 30 minutes of operation, check the coolant level and top off as needed with premixed coolant.
