Thanks Joe, so far my Cummins 180* stat is doing great. It wants to stay at about 183* light cruising, and seems to open about 188* and will drop to 178 on a slight down hill or idle. I did pull one good hill and the clutch came on at 197* and cooled immediately, I was at the top by then. This is with cool outside temps,40's-50's.
