So I'm still working out the bugs in my car and trying to get it on the road. Last weekend I had to pull the engine to replace all the freeze plugs so while it was out I swapped the leaking radiator for one that I pulled out of my old 91rs. The radiator was pretty much new when I sat the car up and didn't have any problem with it at all. For some reason now though it's dripping coolant on the bottom side of the cap. Tried 2 caps so far (one that was on it, and one that come off the old radiator) and it does the same thing.

Now, someone told me that if it has too much coolant they will do this. I've never seen that happen and honestly don't see this being the cause. You can squeeze the bottom radiator hose and it will drip from the cap every time. Anybody ever have this happen? I don't see anything wrong with the radiator that would cause this.
