Detailed Description

Four Seasons 85089 is an engine coolant water outlet made from aluminum for use in the thermostat and housing area of the cooling system. This outlet-style component is specified without a thermostat and without a gasket or seal, making it a direct replacement choice for service work where the existing thermostat assembly is retained separately. The part is engineered to meet or exceed OEM requirements and is listed for 1996-1998 Ford Mustang, 1996-1997 Ford Thunderbird, and 1996-1997 Mercury Cougar applications. The Four Seasons 85089 part number is also useful when cross-checking cooling system replacement needs against OE-style references.

This part cross-references Ford F6ZZ8592B and CH2037 for the same application.

Common Problems This Part Can Address

• Cracked or corroded coolant outlet housing
• Coolant leaks at the outlet connection
• Damaged mounting surfaces at the thermostat housing area
• Improper sealing from a worn outlet assembly
• Cooling system service needs on Ford Mustang, Thunderbird, or Mercury Cougar

Installation Notes and Tips

Verify the inlet diameter, bolt spacing, and mounting flange dimensions before installation. Because the gasket or seal is not included, use the correct separate sealing component for the vehicle application. Inspect the mating surfaces, coolant hoses, and nearby thermostat components during service to help ensure a proper repair.
