1994 Ford Explorer Q&A
1994 Ford Explorer Question: Where is the freeze plug located on my motor?
There are normally several, and they are on the side of the engine block. Look for the leaking coolant to locate the correct one. - Bret Bodas
It is very likely that it is not your freeze plug, and may well be your lower intake manifold gasket. I had this exact same problem with my 94. I replaced the fiber gasket with the metal one that Ford now offers, and problem solved. - rhlandis
