Cooling System Upgrades

Recommended Posts

Maybe I'm getting confused with Eagle stuff, but I seem to recall there being a later model mechanical fan that flows more air than the stock 4.0 Renix one. Maybe it was 97+ with a 4.0?


And isn't there a later model Jeep e-fan that flows more than the Renix e fan? Thanks.

The later model model XJ fan was redesigned, you can tell by the fan blades. I want to say they started this in 97 XJs, but maybe earlier? The pigtails are different compared to the Renix fan, but nothing a soldering iron can't fix.



Thank you sir!

There is also a higher flow mech fan. I just so happen to have one if you are looking for one. Can’t remember the blade count but I have it sitting out in my shop 

I’m not really looking for one quite yet, but if a deal came along I’d interested if you want to sell it.

Upgrade mechanical fan clutch is NAPA 272310. 

They tend to be louder than stock and sometimes fit rather close to the radiator. 

I had read about that. My radiator is larger than stock, so I don’t think that it would clear.

I ran the mishimoto radiator with that clutch and it cleared just fine. That was on stock Mopar engine mounts

Perfect. Thank you, I shall add that to my list. I’ll send you a pm about the fan too.
