Leaking petcock
I have a service replacement dealer radiator in my car. I had recently started to notice that the front support were the radiator rests gets a little damp, and then finally today I saw a small puddle in front of car. I warm up the car to see where it's coming from, and BLAM a torrent of coolant starts pouring out. It turned out to be the radiator petcock. It won't go back in, so I'm at a loss. Do I need yet ANOTHER radiator, or do I just need to replace the petcock?

Replacement petcocks are readily available. Try replacing it first.

Re: Leaking petcock
Well, I forget exactly what the area looks like, but, if there is enough of a nub sticking out of the radiator where the petcock goes in, you could possibly place a rubber hose cap on the end and place a hose clamp over that. Could get you by until you want to change the radiator. Unless you can get a pair of needle noses pliers in there to grab the remains of the petcock and twist it out...Or... and I doubt there room, maybe carefully get a good size drill bit and drill out the center of the remains. Jam a flathead or something in the new hole and twist it out. Lots of potential options.
