NAPA fan clutch #TEM 272318 is the std duty one used on 4.0 XJ's. A hvy duty one #TEM 272310 is standard on 2.5 XJ's. That's the one some owners switch to.

I didn't look up which one a 4.0 YJ takes. The 2.5 XJ takes the hvy duty one (272310). 10 or so yrs ago I tried one from a ZJ but the length of the shaft put it too close to the radiator. Can't remember who it was that turned me on to #272310 but it fits just like the oem one that it replaced on mine. Just moves more air. Having said it before I believe with an oem cooling system in top condition the std duty fan clutch is all that's needed.

When I replaced mine I compared it with the ZJ and noticed the bit of shaft length difference. When I tried to install it I couldn't get it mounted without touching the radiator. No problem getting either the OEM or HD 2.5 mounted though.

I am a little late on this, but there is something that pulls more air. The Taurus 3.8L 2 speed electric fan pulls 3800 cfm on high speed. Whereas the XJ stock fan pulls about half of that. Just saying for the sake of discussion

I have a 4.6 stroker and factory cooling...in the deserts of California. Works just fine.
The best "upgrades" you can do for your cooling system?
MAINTAIN IT.

Hey Ron, you have any trouble smogging that stroker. I have heard various stories on that

clutch fans can suck up to 10-15 hp
e-fan will give you more hp at the wheels and withthe right fan you likely wont see worse cooling
