Any tips for removing a housing that has been in place for many (25+)
years? This particular engine is in a 68 Traveller, and the stub for
attaching the top hose has disintegrated, which does not help the water
circulation or cooling.


YouTube videos on changing the stat seem to gloss over removal of the
housing, which seems to weld itself into place!


I'd try removing the studs. But there is the chance they will snap. If you
have new ones standing by, less likely. ;-) Other thing is heat.
Obviously easier/safer with the head off the car and all water drained.


Otherwise, saw it off. Less chance of damaging things than an angle
grinder.


Just to add, it will have corroded round the studs which is why it won't
come off. You could drill small holes down the sides of the studs to get
some penetrating oil in - just don't drill down enough to damage the
cylinder head mounting face. Use a thread sealer on the new one to prevent
future corrosion.
