The trouble with a flex fan is if you hit mud or deep water its going
EVERYWHERE and probably going to damage the fan.

Ours is a totally rotted rust bucket with plywood floors that we are
only keeping going until I find some money for a better one. Got the
parts machine for a hundred bucks that came with the rad and windshield
I need. Going to strip it for good parts and dump it.
I was originally going to swap engines and use the parts machine, but
both vehicles need complete clutch systems which just isn't worth buying
for them. For that money, I can get another runner. My son just picked
up a 94 Dodge Caravan in 'mint' shape that passed emissions and cert for
$330.00. Well he needed two running light bulbs and a wiper arm...

Cherokee has a new clutch fan and I think the extra electric will do for
now with a toggle switch or maybe I can get the thermostat parts to swap
over and work.
The CJ7 has the 4 bladed fixed fan, no clutch there, it just roars all
the time. A fan shroud also might be in order, it didn't come with one.

Ours is a totally rotted rust bucket with plywood floors that we are
only keeping going until I find some money for a better one. Got the
parts machine for a hundred bucks that came with the rad and windshield
I need. Going to strip it for good parts and dump it.
I was originally going to swap engines and use the parts machine, but
both vehicles need complete clutch systems which just isn't worth buying
for them. For that money, I can get another runner. My son just picked
up a 94 Dodge Caravan in 'mint' shape that passed emissions and cert for
$330.00. Well he needed two running light bulbs and a wiper arm...

Cherokee has a new clutch fan and I think the extra electric will do for
now with a toggle switch or maybe I can get the thermostat parts to swap
over and work.
The CJ7 has the 4 bladed fixed fan, no clutch there, it just roars all
the time. A fan shroud also might be in order, it didn't come with one.

COnsider a aftermarket flex fan because it will move more air at lower
RPMs and feather out a bit at higher speed limiting air flow and noise
and a stock fixed fan does neither. I have a old J20 with a clutch fan
but when I used to work it hard towing horse trailers in summer heat
to trail ride year ago I removed clutch fan and installed a big clutch
fan in its place. Yes it was noisy at times but temp gage never moved
even towing in hot weather and it ran better too because it kept
underhood temps lower as well from increased airflow at all times and
the cab a bit cooler too (it has no A/C) because things where a bit
cooler up front including firewall. .
