thanks, i did see those threads. the reason mine was leaking was because it was cracked. i just wiggled it a little bit and it popped off. the bottom half was wedged in the hole and i managed to push it out from the inside (i did have to take the upper hose off). the little feet were missing though and must have broken off some time ago. i decided i'm not worrying about that. i did find that my upper radiator neck was reinforced...
