Hey all
  A friend of mine and I finally replaced the thermostat in Stella.
Well actually I wound up putting it in upside down, but we over came
that little obstacle.  It's amazing how helpful books can be.  Any way,
to the point already... I have noticed that the housing is leaking.
I've went back and re-tightened everything.  I have also cheched the
hoses, and they appear to be dry.  I think it is leaking from the back
of the housing where the top and bottom meet.  Any suggestions?
