Seems the system also might work better when tractor is run at a higher rpm. You might have to experiment with that theory. Make sure your exterior radiator fins are clean and not blocked. Air must freely pass through there for proper cooling. Interior radiator cores must also be clean. If you haven't, take the upper hose loose, stick a water hose in there and flush everything out real good.
