Tom, If you've not tried one yet, get a pressure tester. It is pointing me in the right direction. At first I could only hear hissing. I added water and the leak showed up. Now I'm hoping it is only one leak.

Maybe someone had a similar occurence and can give me some advice. The problem that I'm having with my car is that it leaks coolant somewhere at the water pump but only when the engine is cold and the temperature drops below 50 degrees. I don't know where the leak is, it appears to be somewhere behind the pump.
