[Spridgets] Thermostat housing removal

[derf247 at gmail.com (derf)]

A well placed tap on the base flange with a hammer and blunt punch
should do it.  If not you may have to break it and chisel the pieces
off.
If corroded in place soak with PBBlaster or similar for a while.  But,
it shouldn't be that hard to dislodge.
I assume you got all the bolts out.  If not, do that first.  Usually
in my experience if there is a problem it is with the bolts and not so
much the housing itself.
