Detailed Description

Dorman 902-217 is engineered as a direct replacement engine coolant thermostat housing for the listed vehicles, including Ford Mustang, Ford Thunderbird, Mercury Cougar, and Lincoln Mark VIII applications. The aluminum construction is selected for strength and resistance to repeated temperature swings, helping the housing maintain service life in demanding cooling system conditions. The housing includes the gasket and O-rings needed for the sealing surfaces, while the thermostat itself is not included.

This part cross-references Four Seasons 85000 and Standard Ignition 7302 for the same application. Use Dorman 902-217 when replacing a cracked, warped, or leaking thermostat housing on compatible Ford Mustang cooling system setups.

Common Problems This Part Can Address

• Coolant leakage at the thermostat housing
• Cracked or warped housing surfaces
• Improper sealing at the outlet neck
• Corrosion-related housing deterioration
• Cooling system service on a worn OE-style housing

Installation Notes

Verify the outlet port diameter, mounting hole layout, and 90-degree neck orientation before installation. Clean the mating surfaces thoroughly and inspect the thermostat and adjacent cooling components for wear before reassembly. Because bolts are not included, reuse or source the correct fasteners for the vehicle as needed.

Quality Assurance

This replacement housing is designed to match the fit and durability of the original thermostat housing on the specified vehicles and to withstand extreme temperature changes for extended service life.
