Either way if you know for sure your leak is coming from the radiator just do yourself a huge solid and buy yourself a new one and call it a day...I guarantee if you put a new one in it wont leak and there is no bypass valves or any other crap that will cause your new one to leak.
or coolant can come out an overflow. I was just trying to make sure this didn't have some kind of funky overflow system that came out the side of the radiator. I wouldn't think so, because where it's dripping from makes the coolant go on other stuff. thanks for all the help. I will probably try to patch it from the top, since it's a pain to take the radiator out. if not, I'll replace it. thanks.
