From the pix you posted it appears the bolt retaining the housing was so corroded that when removal was attempted the housing broke apart.
If you find a used one , you might want to soak it with plenty of penetrating oil to allow the bolt to loosen without taking the housing with it.
Also a good move to apply some anti-sieze or grease to the bolt threads so it can be easily removed up the road, if necessary.
So a junkyard I went to today had about 2 dozen Taurus’ a few Escapes a Mazda MPV and a couple Mazda M6’s. Only about a quarter of the Taurus’ had the Duratec engines and none of them had a Thermostat housing like mine.
I ended up taking this one from the Mazda MPV. It’s got the same shape as mine but it doesn’t have the coolant sensor. I’m thinking I can add it be drilling and taping or adding a coolant sensor at another spot on the engine.
One thing I noticed about my Taurus is that the coolant line transverses across the engine bay to the passenger side. Most of them at the junkyard attached to the radiator on the drivers side.
I must have a very unique and rare Taurus. I should auction it off on EBay!
