I would look higher up. Coolant leaks are usually hoses and hose clamps. And there can be clamp leaks that don't leak cold, don't leak hot, but leak during warm up. I would just go around and snug every hose clamp, unless you have the spring clamps that the factory uses that take pliers to release. They are aggravating to deal with, but are the best clamps to use.
