Becuase its dripping form the middle doesnt necessarily mean that is where it is coming from. But your lower radiator hose, a freeze plug, heater hose could be trickling from the water pump too. You have to look really good to find out where exactly its coming from, as you know liquid can travel down creases and crevases and be deceiving as to the original location

It happen to me before it was slowly leaking in the center underneath the car but I could not find where it was coming from, all the hoses and radiator were dry so then I started looking elsewhere starting with the temp sending unit located on top of the motor and it look like it was wet and leaking but then I look above it and saw more wetness which was coming out of the intake manifold, new gasket installed and no more leak, by the way the 3.1 motor is known for "Intake Manifold" Gasket leak something to do which the recommended antifreeze. I just use reg stuff now.
