Mine used to float around then my rad sprung a leak. So I chaged it out along with all the hoses and put a new Cummins T-stat in. I also used Global Charge coolant and flushed the system. Now my gauge climbs up to 180* and rides it....it moves a little in the summer when towing but usually stays right around 180* all the time. That actually bothered me for a long time cause I was used to the temp gauge swinging.
