David, Anything you would do involving water is out under these conditions.I don't know if something like this is available,after all,this is 2010,if you could charge the system with some kind of colored gas,then pressurize with dry air you may be able to see where the leak is located. Otherwise,you may have to shut down the freezer & do this operation with water :(
