Is it the radiator or condenser coil? If its the condenser coil that is a high pressure high temp gas to liquid refrigerant running thru there (R-134a). I am guessing its all aluminum construction. You could evacuate the charge and try and fix it, however you will probably end up just replacing it.

I do HVAC also (Engineering side) but use to be a tech. You could try to use epoxy, but again as you know the head pressure can get pretty high when its gets warmer out.

I did the zoodad mod with just a hole saw. Make sure all the refrigerant is out of the system before trying to fix it. The pressure from the refrigerant and the oil will make it difficult

I would recommend just buying a new one as if you get one from a wrecker it will work but if the condensor is exposed to air for more than a short time period your asking for trouble as moisture will collect and cause corrision once its in then down the road contaminating the oil and destroying the compressor, and other parts of the A/C system..
