You really should consider just changing the clutch if it's bad. An electric
fan might work OK for idle cooling, but when you're working the engine hard
at lower speeds the electric may not be enough.
They designed it with an engine driven fan for a reason. In fact, I don't
recall any off road vehicle that doesn't have an engine driven fan. My
Cherokee has an engine driven primary and electric secondary.
When you're working it in 4 low you can really hear the engine driven fan
kicking in. You won't get an electric to pull that much air.
Rigging an engine driven fan that is supposed to have a clutch so that it
does not have a clutch is going to hurt your horsepower. It will cool like a
mutha, but it'll bog your engine down and sound like a jet going down the
road. lol.
I believe your best bet is to replace your fan clutch. If you find you are
still overheating at idle, then add a pusher electric to the front of the
radiator if there's room.
But you don't want to trade good idle cooling for bad high-load cooling.
(ie. electric fan only). You can always give the engine some acceleration
while you are winching if it's getting hot (with a new fan clutch it likely
won't get hot). If the engine is providing the power to the winch, then
winch in 4 low or neutral if you can. It will get your engine rpm up and
increase fan speed. (Of course, with a good fan clutch)
Good luck.
