Got a 93 Suburban, 5.7L, that developed a small coolant leak earlier. Its coming from a small, round hole on the bottom of the radiator, almost directly beneath where the lower radiator hose goes in on the passenger side. Again, its very minor so far. After I park it, it will leave a spot about the size of a half dollar, and that's it. Of course, its irritating the hell out of me, though.... I'm not even sure what the purpose of that hole is. Could it be leaking from somewhere else and running out through that hole, or is it a drain plug of some kind. I can't see it very well, and I wanted to get some advice before I start tearing out parts. No problem with overheating, and no coolant coming from the water pump or hoses or the hose connection. As always, thanks for the help!!!
