Radiator and efan recomendations please

[EUREKA]

Due to a auto accident I have to replace my radiator and AC condenser. My aux trans cooler appears undamaged. I do tow every week. Sometimes nearing 5000 pounds. 

I was considering eliminating the mechanical fan ans getting an all aluminum radiator with e-fans. Any recommendations?

Thanks

generally speaking, mech fans pull more air than efans.  frequently waaaay more air.

Even at low engine rpm? Maybe I'll stick with the stock fan set up.

I would definitely upgrade the efan to a late model XJ fan.

I’d do a new fan clutch for the mechanical fan, a late model XJ efan, and a Mishimoto radiator.

I think this is the route I will go. 

My clutch was at most 5 years old but both of my fans toast from the car wreck, as well as the shroud for the mechanical fan.

The ideal recipe I found for my 4.0 MJ was a mishimoto (or cold case) radiator, heavy duty Hayden fan clutch from a ZJ, a good 7 blade mech fan, and the late model XJ 10 blade e fan (but get it on a 40a relay with good solid wiring) and make sure to run the mechanical shroud. Good good, quality stock flow water pump (I dumped my flow kooler for an AC delco gold pump). And some quality stainless hose clamps that don’t bite into the hoses. If you want to go all out, get the Novak radiator for an AMC engine. Thickest core and highest capacity currently available afaik, though it will require some slight mods. But I’d recommend not running triple e fans on a stock electrical system. There isn’t enough amperage available to maintain charging voltage, and those e fans need to run at charging voltage (~13.8-14v) to flow enough cfm to cool.

So the fan clutch from the ZJ will be slightly more parasitic and slight louder buy cooler better? I do have a 136 amp alt but yeah i think I will not go with the 3 fan set up. I found my flowkooler to be a decent upgrade.
