Detailed Description

This Dorman thermostat housing is engineered for cooling system service where the original water outlet has cracked, warped, or no longer seals correctly. The housing is shaped to match the stock configuration on select Chrysler Concorde, Chrysler Intrepid, and Dodge Intrepid models, helping maintain proper coolant routing through the engine coolant thermostat housing assembly. Dorman 902-771 is a practical replacement when you need a housing that follows the original fit and mounting layout without changing the cooling system design.

This part cross-references Dayco 85044 and Gates CO34797 for the same application. It also aligns with other listed interchange numbers for the same fitment family, including Dorman 902-771 in service catalogs and related aftermarket references.

Common Repair Uses

Installation Notes and Tips

Verify the outlet port diameter, mounting hole layout, and 70-degree neck angle before installation.

Clean the mating surfaces thoroughly and inspect the cooling system for related wear before refilling with coolant.
