To the best of my knowledge, the ONLY things you ever need to put a sealant
on are those specifically stated in bentley.

My understanding is that when properly assembled, new o-rings and gaskets
should properly seal without any "help".

Looking for RTV or other sealants is a good way to determine if someone knew
what they were doing when they rebuilt or fixed an engine.

Hope this helps,

  Subject: Any recommended sealant for o-rings?

  Volks:

  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.
