31, that could be my issue with the 48 Merc 59AB. Finally found a temp sensor that worked after changing both water pumps. Have old 180 in there and temp gage goes 3/4 then higher on idle. I understand 160 stats send gage to 1/2 if cooling system OK. Car has 2000 miles on total rebuilt engine, bored +60 in 1975. Did notice recently that radiator is hot at top and NOT hot at lower hoses. I'm flushing with Thermo-cure and installing 160s. If that doesn't do it.... I'm in trouble. This is a 990 point Dearborn car. Anybody wanna jump in on this?
