Detailed Description

This Dorman thermostat housing assembly is engineered as a direct replacement for the original coolant outlet housing used on select Ford F-150 and Lincoln Mark LT models. The aluminum body helps resist distortion from heat cycling, while the included thermostat and O-ring seal support proper coolant routing and temperature control. Dorman 902-5153 is a practical choice when servicing a leaking, warped, or cracked thermostat housing on a 2011-2020 Ford F-150 or a 2021-2025 Ford F-150 with single alternator configuration, as well as 2011-2014 Lincoln Mark LT vehicles with the covered housing and thermostat setup.

This part cross-references Ford OE number BL3Z8A586A and Four Seasons 86013 for the same application.
