(Despite what Bush say.) Yea, come down. I know some American rocks that said "Canadians can't wheels" and need to be shown better.
Or you could order it over the net. But that don't get your wheels dirty do it.

Looking For More Airflow
Alright I am looking for a more airflow on my '91 4.0 w/AW4 as well, and it appears that this Napa 272310 is a bolt in upgrade. I currently have a stock replacement, a Hayden 2625, which does lock up, but not until everything is already pretty hot. Stock is likely fine for flatlands, but on the trail and the steep roads I drive to work (16% grades normal) it seems like it just keeps creeping up.
I also run the CSF 3 row all metal rad, and sounds like it still fits, though I thought I remember reading it is VERY tight? I have Prothane solid motor mounts so I am guessing I won't mow down the back of the rad while wheeling, sound correct? Everything else is new, pump, tstat, housing, hoses. Oh, and I could care less about any noise - noise means airflow!
Finally, I have a later model eFan - the one with the S shaped blades and I would like to know if anyone has found a shrouded replacement or upgrade that can fit in there. Has anyone replaced the fan blade assy on the oem mount? Actually tearing into a spare electric motor to see about upgrading it on the oem mount with blade assy here at our shop as there is a motor rewinding shop here too!
Thanks for your input.

Re: Looking For More Airflow
This is the only part I can answer - I run the same radiator and the ZJ fan clutch and it's fine. Definitely wouldn't want to do it with stock/worn out motor mounts, but with upgraded mounts from Prothane, Ironman4x4, Brown Dog, etc, you won't have any issues.

Nice Upgrade! NAPA part 272310
Hey that NAPA part 272310 is a nice upgrade! With AAA discount it was $41 and change out the door.
YES, it does make more fan noise because it is putting the fan to work, but I could care less because of the improvement - It moved my temp needle from riding on the 210 mark about 3/16" cooler to the left, and it stays there up a 2 mile 13% grade without eFan use.
I still have to conquer the heat on the 17% twisting grade that's about 1 mile long at 25mph - it still creeps up so I am not there yet. It goes up until the eFan runs and halts there - but that's a different thread I suppose.
OH, the clearance! This thing is really only about an 1/8" taller than the stock fan clutch because the stocker has those "wings / blades" that stick up from it. However it is a Lot larger diameter, it almost blocks some of the fan, but spins the fan so fast the point is moot - it really cranks out the air - I wonder the CFM now.
Has anyone had this clutch fully engage on a hot day? How loud was That!?! :yap:
Cheers.

I just loosened the top nuts and rocke the rad forward 1/2inch or so n tightened it up.
A piece of poster board against the rad fins spares the fins and your knuckles fwiw.

Unrelated but I have been having some issues on my Cherokee again with it running a bit warm.
I used this fan clutch from 2010 to 2014. Swapped in a Hayden fan clutch for a 4.0L Cherokee - 2 years later it went bad. I was able to jam a pencil in it with the engine running at 220 and it stopped. So ... I thought I would put this one back in.
However, I threw it out 2 years ago when I put in the "regular" fan clutch.
I just called Napa and asked what it interchanged with. I didn't see it on any sort of ZJ in the junkyard, however, when working on a friend's 2.5L Cherokee, it looked identical.
According to Napa, it's the 4 cylinder fan clutch from a 2.5L YJ TJ and XJ.
