There were a couple of MK8's in the Clearwater Cophers the other day but I can't remember if they had fans still. A 4.6 TBird fan should work also. Just make sure you use a 30-40 amp relay to run it. Another thought would be to add some Water Wetter from Redline. I bought some at PepBoys a long time ago so not sure if they still carry it. Every little bit helps. If you get a fan and need help with the wiring PM me and I can give you the wire colors off of the one I have.

One more thing. You mentioned that the radiator and condenser had all sort of nasty's in them. I have used refrigerator coil cleaner on these with good results.
