Brandon,
I had to have the vehicle towed to a Ford dealer because I was out of town. They did the repair. They replaced both pieces of the two piece thermostat housing. I didn't know it was a two piece housing. It might be the 8592 and 8548C parts in your diagram. I would call a dealer to get the exact part numbers though. Sorry that I can't be of more help.
