All metals expand when hot so it's probable it only leaks when it cools down as the metals contract. A bad water pump gasket would do that...heats up and seals, cools off, contracts and leaks.

Leaks flow down from gravity and back from air blowing from fan. Just have to follow the water. They also make a florescent dye you put in the coolant and a special light to see the dye
