Detailed Description

This engine coolant thermostat housing is designed for cooling system service on classic Ford and Mercury vehicles where the original housing has corroded, warped, or cracked. The metal housing is built to match stock fitment and support reliable coolant flow at the thermostat connection. The bleeder valve helps release trapped air during filling and bleeding, which is important for stable cooling system operation. This part cross-references DENSO Auto Parts 4099 and Motorad 4818KT for the same application. Use Dorman 902-1024 when replacing the thermostat housing on 1965-1971 Ford LTD, 1968-1970 Ford Mustang, 1968 Ford Thunderbird, 1969-1971 Ford E-100 Econoline, 1970 Mercury Cougar, 1969 Mercury Marquis, and 1975-1976 Ford F-Series trucks.

What It Helps Fix

• Coolant leaks at the thermostat housing
• Cracked or warped original housing
• Air trapped in the cooling system during service
• Corrosion at the thermostat mounting area
• Improper sealing at the coolant outlet

Installation Notes and Tips

Verify the outlet port diameter, mounting hole spacing, and housing neck angle before installation. Clean the mating surfaces thoroughly and install with the included gasket to help achieve a proper seal. Confirm thermostat fitment separately, since the thermostat is not included. Bleed the cooling system after installation using the built-in vent to remove trapped air.
