If hard to find while engine is hot do a pressure check on your cooling system while engine is cool. Local auto parts will loan you what you need to do the check. With use of small inspection mirror you should be able to identify the leak.

I'd bet you any money it is your coolant elbow. They are made of plastic and tend to crack. Best thing would be to find a replacement aluminum elbow, (Dorman has them)
