yeah, but for some reason the bolt was damaged and was preventing the line from coming out of it, so I had to pull the bolt out of the radiator and do it on the bench. Even on the bench, that bolt was boogered up enough that it wound up breaking the thin end of the bolt past the hole that the clip goes into. I'm just relieved to hear that it's normal for coolant to come out of that hole with the nut removed. I still don't understand why, but I'm ok with that.
