Product Details

This engine coolant water outlet is intended for vehicles that need a replacement outlet housing rather than a thermostat assembly.

This part cross-references Motorad CH6039 for the same application.

Common Cooling Problems This Part Can Address

• Coolant seepage at the outlet housing
• Corrosion or pitting at the original water outlet
• Cracked or warped coolant outlet surfaces
• Improper sealing after thermostat housing service
• Loss of coolant flow connection at the engine outlet

Installation Notes and Tips

Confirm the inlet diameter, bolt spacing, and mounting flange dimensions before installation. Clean the mating surface thoroughly, inspect the thermostat separately if replacement is needed, and verify that the gasket or seal seats evenly before tightening fasteners to the vehicle service specification. This Four Seasons 85018 water outlet is supplied without a thermostat, so reuse or replace the thermostat as required by the repair.
