I'm not sure if it will physically fit in your dak correctly.. but for a 3.9 L I'm about sure the GC or the newer GC would keep you nice and cool. Other wise you could go the route of the Ford Fan's..
I'm still trying to work out shipping costs for the one fan.. I have the other one from the 2011-2014 that comes with a shroud.. that is listed in that e-fan project post, it covers about the entire rad.. the one photo'd as I'll be just using my dak to haul the boat to the lake.

We could work something otu if you wanted it.. i was keeping my 5.2L cool with AC on it was about 90 outside in the evening keeping about 190ish pulls about 40 amps. Let me know if intersted i leave out of town for a few weeks come Tuesday so i only have till Saturday to UPS something.

 

3.9/5.2 use same radiator I believe. 3.9 we just have an extra 6 inches between the W/P and radiator.

 

That's right.. its the same.

 

wait your saying a guy local is selling GC fan for $25 or the fans for the van?

If its $25 for GC fan that's a good price. QC fans go for about 80 new at dealer (if they ahve them) rest are Aftermarkets that are about same price but not Mopar brand so you pay for what you get.

I just paid 100 bucks for this shrouded 2011-2014 GC aftermarket fan but being shipping is high i might work something out on it to get rid of it

 

The 2001 GC fan is sold i have the 2011-2014 GC fan/shroud i just bought and modified to fit our truck if interested still.
