I just checked Oreilly and they sell both the 9 and 10 blade, the 10 blade comes with a severe duty clutch as well.
Just stopped by Autozone and ordered fan and clutch. They won't be in till Wednesday but it should be about a five or ten minute job to make the swap. 250 mile drive on Thursday to Killington for Jeep Jamboree (and back on Saturday night) so will try it out right away, although admittedly not at temps that many of you see. Haven't had an overheating problem but as I approach 100k miles I start to think about doing anything I can to make life easier on engine and transmission. Worry about breaking something that isn't broken but easy to go back to stock if I don't like it for any reason.

Personally I dont think this is an upgrade worth doing. I think the improvement(if any) is going to be negligible......more blades does not equal more air movement, especially when the blade angle is reduced....I like the thought of upgrading this area without question, but this does not seem to be the ticket.

Why does the Jeep 5 blade fan get replaced by a 7 blade when the rig is hard to cool?
Why are there two options for the plastic fan which are 9 and 10 blade and the 10 blade is generally coupled with a severe duty fan clutch?
If I were to apply your logic, should I remove every other blade on the 10 blade and make it a 5 blade?
And for the record, blade angle is referred to as the PITCH. So what's the ideal pitch we need and how many blades for hot climates?

Funny: Will it fit in my Jeep?
I spent today out in the desert in 100* heat with the AC on. On a long slow climb it did get up to 215* then the fan clutch locked in and immediatly brought the temp back to 205*.
215* is perfectly acceptable on a hot day with the AC on and pulling a very steep hill at a walking speed. With the Jeep fan I would have hit 230* which IMO is the hottest I want it to get.
The Ford fan is much quieter than the Jeep fan. IMO thats reason enough to use it. The Jeep fan makes all kinds of noise when the clutch locks up.
I want to do this mod, but Autozone lists different fan and clutch part numbers for the 2.5 and 4.0 models. I have the 2.5. Does anyone have a definitive answer as to whether or not it will work on the 2.5?
