Can you take a picture? Reason I ask is, I can't think of any bolts in the radiator that would leak.

If you clean the gunk off is there a metal clip? That looks like the transmission cooler line quick disconnect fitting.

i would agree, you cant tell if its years of grime or something current unless you clean it then look for leaks. as far as the connector i believe that type pulls out. it is a quick connect type the nut part seals against the rad and the ring holds the tube in
