Coolant Leak on 2002 Ford Mustang GT

I am leaking coolant from the bottom of the radiator. It only leaks while running and immediatley stops when shut off. I cant really see where it is coming from but it appears to be dripping from the passenger side lower radiator mount. It is a sizeable leak and I need HELP!!!

The reason why it only leaks when running because the system builds pressure as it heats up. You can find a shop here and check prices here and usually if its dripping from the radiator either the radiator hose is leaking or the radiator itself and a shop will pressure test this to know exactly what is leaking
