No the o rims don't need any sealant, only a clean surface and proper
torque.

Yesterday I started replacing my thermostat and performing a drain, flush
and refill on the coolant system on Miss Blue, my '87 GL. In removing the
top to the thermostst housing (TH), 2 of the bolts sheared off. I had to
remove the lower part of the TH from the engine block in order to drill out
the sheared bolts. There is a rubber o-ring gasket between the TH and the
engine block that I will replace when I reinstall it. Should I put any sort
of sealant on this o-ring when I reinstall the TH? Any suggestions would be
appreciated. TIA.
