Follow the upper radiator hose to where it connects to a black metal tube behind the alternator. Follow the metal tube down to the engine. This is the thermostat housing. Is that where the leak is? If not, you'll have to either rent or borrow a pressure system tester from someplace like Autozone, Pep Boys, or Advanced and pressure test the system, or buy the leak detector kit I mentioned.
