What It Helps Address

• Improper sealing at the cooling system outlet

• Service issues on Jeep Cherokee, CJ5, CJ7, J10, J20, and Wagoneer cooling systems

Installation Notes and Tips

Verify the outlet port diameter, mounting hole spacing, and neck angle against the original housing before installation. Clean the mating surfaces thoroughly, inspect the thermostat separately, and replace any damaged coolant hoses or fasteners as needed. Because the thermostat is not included, transfer or replace it based on the vehicle’s service requirements.
