I can see it dripping off of a pipe that runs under the radiator. Supposedly the radiator is new, so I would hope that isn't the issue. Assuming I get the pipe plugged, what other leak issues should I look for? The coolant level is always low when I check it.

 

gravity messes with you on this one. jack the car up and let it run to see exactly where its coming from. could be a crack in the hose or a crack in the radiator.
