This is the best suggestion. An iphone (LED) light will (generally) also show the dye when the bilge is dark.
Go to your local auto parts store and buy a bottle of leak detecting die and a cheap UV flashlight if you don't already have one. Put the die in the cooling system and after a run get the flashlight out. The die glows bright green with the UV light and you should be able to see where it is coming from. Its amazing how far fluid will travel from the actual leak point.
