glenmore, I think you said that the tstat was broken but you didn't say that you drained and refilled the cooling system (although you probably lost some fluid when you took out the tstat). but you probably did drain everything and refill it right? I'd wonder where are the broken pieces parts, you know? Are they floating around ready to do damage to a water pump or something...
