GenGoku, I see you had the core submerged in that bucket of water, are you positive it is not just water in-between the fins from that, now coming out when you shake the rad.
a sure fire way to test is to completely submerge the rad under water, (in a bathtub or whatever..) then, while having the one inlet sealed off, put some air pressure on the other side, blowing on it should suffice. then see if you can blow bubbles with it... If not, then the droplets you got from shaking, was just trapped water in the fins......
