Bluebee - thanks for all the info (I'll thank CN90 later)
I'm preparing for cooling system overhaul, and have spent hours reading all the related posts I could find, and still have a question:
Should I use any sealant on the thermostat housing & housing bolts? One thread used black silicone if the head was in rough shape.
On other cars I've always used Permatex (II I think is the non-hardening kind), but I don't recall seeing this covered.
Thks in advance
