it's the thermostat housing elbow, once leaking you have to buy the whole thing, the elbow plus the housing, there is a gasket and or an o-ring in there ..but because of age of plastic ..the whole housing will probably fall to pieces or crack when you try to dismantle and may be cracked somewhere already ..so probably best buy the lot complete with the thermostat.
Note: there are several different versions of this housing ..so be careful when you order it ..prices from ebay NEW - as low as £12 ..ford dealership - probably over £100
I would not buy a used one off ebay ..even if genuine
all the best.mark
