Be gentle squirting air into the radiator, they are delicate.

Ron,
Is there any reason why both the water and air fittings couldn't be installed in the blockoff plate, so that one doesn't need to drill holes in a good outlet?
I like this idea. I'm going to try it on an old replacement radiator that I think is good but has a lot of rust stuck in it.
