Thanks for the replies. Pulled the t-stat and tested it, doesn't open til almost 200 deg. Water pump seems to going the correct way. I think I may have a bad t-stat. I'm going to try to get a 160. Also may have air trapped under t-stat, might try drilling a burp hole in the stat. It's just such a pain to r & r the t-stat with the pullies an belt and no room to work.
