DieselSite OEM Upper Neck / Thermostat Housing for Ford (1994-97) 7.3L Power Stroke

Replacement Ford thermostat housing (upper neck) for the 1994-1997 Ford 7.3L PSD.

In many cases, when changing the thermostat, the housing does not want to re-seat and seal properly. They are made of stamped steel and are not treated very well from the factory against rust. They rust and the seat becomes very uneven. We offered this part for those that wanted to eliminate the chance of leaks when changing your thermostat.
