How many & where are locations of the freeze plugs. I have replaced 2 so far on 1995 Ford Windstar

When I pour water into the radiator it just runs out in the vicinity of the water pump area. I have replaced 2 freeze plugs that gave the same symptoms. How many are on this vehicle and where are they located so I can zero in on the problem.
