For what its worth....Ford has built engines with two waterpumps. The venerable flathead V-8 from 1932 to 1953 had two waterpumps - one for each bank of cylinders. I ought to know, I learned to drive in a Ford pickup with the 'high performance' version (100 hp) of the 231 cid V-8. Yeah, I KNOW I'm old.

-Mark- '99 Mystique LS, totally original (including the original water pump and the premium stereo)! Bought new in December 1998 for $21,000. 208,000 miles
