I agree with dj and rangerlocal . Could be the water pump. I would stop driving. The 3.0 heads do not like to over heat. They will fail.
This is what i would do.
-do a combustion test to eliminate head gasket.
-investigate and find the leak. Repair as needed. No matter what install a new motorcraft tstat.
