Thermostat housing leaking like Crazy!!Peter,

You will need to obtain a rubber gasket.  Also, do not tighten too tight.  Tight is not necessary good. Get a good torque wrench and tighten to specification.

Good luck,

  Dear Syncronauts
     I just installed a new thermostat in my '87 syncro and carefully put the housing back together and the housing is leaking like a sieve !!
  I took it apart again and cleaned it all out where the top & bottom of the housing meet.  Everything looks fine!  I carefully put it back together, poured in the coolant again and its just raining in there!!!  I cant figure it out! Its not even under pressure! There are two flat surfaces that come together and are flush (the top half & the bottom) and there's a screw at each corner that holds them in place.  There's no rubber o ring or anything like that to make the seal.        
       I can see the coolant just flowing out in between the seam.  It looks flush! I carefully screwed it down tightly with alot of pressure.  But not so much as to crack the plastic top.
   Any ideas?? Thanks,

  Mystified,

  Peter
