Replaced thermostat. Used aftermarket cast metal one. Shall see if any differance. From my observations of the old one still on engine, looking from under car, leak appeared to come from bottom bolt area. Thought maybe a crack. Upon removing and inspecting the old one it was actually leaking from the center portion where the electrical stuff is. Not the outer seal as speculated. O ring inside electrical connector bad. Not something to repair.
