I have been on the hunt for some used e-fans for my 2001 SCREW W/5.4. It seems the popular choice is fans from Mark VIIIs, but that being the case they are getting scarce in junk yards in my area. I did find a set of two 16" fans in a double shroud from a 2000 Pontiac Montana that looks like it would fit the F150 very well. The fans look to be pretty quality and the price is right. I am a bit hesitant though because I know nothing about these and have not been able to come up with much info on them, does anyone know anything about these fans?

 

Don't know about the montana fans, but i've been looking at the Lincoln contenintal fans they are also a double 16" fan with a shroud. Might be another option

 

I can't speak for the quality or dependabilty of those fans in particular, but it's an extremely safe bet that 2 of any 16" fans are going to do the cooling job. That part won't be the issue.
