Detailed Description

This Dorman engine coolant thermostat housing, part number 902-1001, is engineered for direct replacement service on a wide range of Ford cooling system applications. The metal housing is built to handle repeated temperature swings, helping preserve sealing integrity where coolant flow and thermostat control are critical. It cross-references Carlson 7073 for the same application.

Use 902-1001 when servicing cooling system housings on vehicles such as the Ford F-150, Ford F-250, Ford F-350, and Ford Bronco, as well as select E-150, E-250, and E-350 Econoline models. It also covers many classic Ford, Lincoln, and Mercury applications where the thermostat housing mounts to the engine coolant passage.

What It Helps Fix

• Coolant leaks at the thermostat housing flange
• Cracked or warped original housing surfaces
• Corrosion-related sealing problems in the cooling system
• Improper thermostat housing fit after prior repairs
• Temperature control issues caused by a damaged housing seal

Confirm the vehicle’s engine and housing style, especially on Ford F-150, Ford F-250, and Ford F-350 models with threaded-port or upper-position configurations listed in the fitment data.
