I already mentioned it in this thread: the t'stat. If the engine has a 195 stat, then your numbers are good.....& nothing to worry about. The temp is never going to be below about 195-200 if the engine has a 195 stat. Radiator out of a Mack truck will not lower the temp.
So you need to check what stat is in the engine before spending $$$$.
I talked to the mechanic who worked on the car he said it’s a 180 t stat and that he take the previous owner to install a new radiator and a fan shroud so I’m going to give it a shot. The current radiator is seeping coolant
