The non pressurized cap is way different than a pressure cap. The non pressure cap is retained like a gas cap. It cams under lips on the inside of the filler neck. The pressure cap is identical to those found on automobiles of the 50s, and 60s. It has a spring and gasket that go into the neck with an atmospheric valve in the center of that. (lets air into the radiator when the temp drops back to ambient.) The cap has external tabs that cam into external ridges on the top of the neck. If your cap is fitting correctly, and it is an inside tab and lip, it is a non pressurized radiator (even if it is on a tractor that had the pressurized system, it is a radiator that should not have pressure in it) If it is an external tab and flange cap (as your dad seems to think) then it is supposed to have a 7 pound pressure cap on it. If the existing cap has no spring or gasket, and or no atmospheric valve, it could be that someone modified it to be non pressurized. The correct cap is available from many sources. Jim
