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

attaching the top hose has disintegrated, which does not help the
water circulation or cooling.

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.

is that similar to "muckite"?

Often wondered why this stuff seems to rot away so easily being mainly
zinc?

Go on, have a guess...
