If it is coolant, it is probably leaking on top of the engine UNDER the intake manifold and running down the back. Is there a strong smell of AF when you open the hood as it would have to leak a lot to fill the space under the manifold to then spill over. Pressure washing the underside of the motor will make it MUCH easier to really identifiy where it is coming from. Check your oil to make sure it is not contaminated (which would indicat a bad thing) as well as opening the radiator cap for inspection. I don't believe it is leaking from the are you indicate as it is behind the main oil pan / engine - it is simply running down there.
