Have you checked the radiator itself to see if there is a leak coming from there? ALso, you could pressure test it yourself. The gauge screws on to the radiator inplace of the cap. Many parts stores will lend or rent the tool to you. Also, there is a dye you can get to place in the coolant to help you trace where the leak is coming from. The dye shows up under a black light.
