might be a good time to put in a new thermostat. make sure its 170deg larger-OEM-type, not cheap aftermarket. I think Stant and now maybe wix and NAPA offer soob -specific ones. Test the new one on the stove if possible, just to be sure it opens around 170.
burp the coolant system well.
be careful with the tensioner - either re-using or if you make a mistake and have to re-compress the new one - do it glacially slow.
good luck
