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!!!
