If that is the case, I almost certainly need more radiator.
That's what you need to do. Don't waste time do it now.
so if you are heating a small pot and it boils over , use a bigger pot and it will take longer to boil over . either way it boils over.. you either need less heat being put in or do a better job of taking heat out . ie> improve the efficiency of the air passing through or give the rad .more time to remove it... thousands of fools are using the correct pulley size to get the water flow where it needs to be and the parts stores are glad to be selling them what they dont need. just trying to help. not offended ............
