Re: pressure test radiator

I agree with Steve, I'd have it checked by a professional radiator shop, and most especially checked for flow rate, that radiator is no joy to have to remove a 2nd time if it's not up to the job! But if you want to just pressure test yourself, with a snug-fitting radiator cap you could put it on, turn the radiator upside down, and rig up a simple adapter to pressurize from what was the lower gooseneck. A large rubber cork/stopper would be the basis for adapting your pressure test apparatus - such corks commonly available at swimming pool supply houses.

Not sure what pressure one might use to perform a test, but of course you know the system is a non-pressurized cooling system.

Packard gravity flow-rate specification is 30-34 gallons per minute.
