Any tips for removing a housing that has been in place for many (25+)

Can you get the bolts out or is that the problem?

I seem to remember that often the bolts came out OK but the housing
tended to be rather well glued in place by the gasket cement.

Do you need to preserve the thermostat housing? If not then just
break it,

Oh, you will break it, trying to get it off. They're made of cast
easilybrokium.



Surely it's already broken if the bit where the top hose fits has
disintegrated. It will have to be replaced - so it's extreme violence
time, but try not to damage the head.

IIRC, it's held on by 3 studs which screw into the head, with nuts and
washers on top. If you can get the studs out (use two lock-nuts if
there's enough thread) it will allow the housing to be rotated (metal
bar for leverage in what's left of the hose outlet), which may break the
seal.
