One tricky leak source is the drain valve on the radiator. If it's loose at all it will seep fluid while under pressure. The large hose connected to the bottom and running up to the pump is also a possible leak source, specifically where the hose and radiator meet. Sometimes the hose shrinks and degrades at that point and if the hose clamp isn't tightened to compensate for the shrinking rubber, it'll leak. Solution is either tightening the clamp, cutting off a half inch of the hose for a "fresh seal" (plus cleaning the surface of the radiator port where the hose is fitted) or replacing the entire hose. This same degrading hose issue applies to all coolant connection points. It'll leak only under pressure.
