From my quick search on Rock Auto, a Jeep CJ with a 258 calls for a different fan clutch than an Eagle. Does anyone know if a CJ with a 258 fan clutch will work? Or does anyone know of a heavy duty fan clutch for an Eagle? I'd even settle for a fan clutch delete.

I don't like how my temperature is creeping up in stop and go traffic (AZ heat, newer water pump, working thermostat, clean cooling system, stays cool at speed). My shroud is in good condition, but my fan clutch was a cheap one when I got it three years and 6000 hard miles ago. Now that this car is my daily driver, its time to get a good, heavy duty fan clutch on it.

When I got a new fan clutch I just went to AutoZone and it has been working great. I can't compete with Arizona temps but it has worked well in up to 98°F for the last 3 years I have had it on my car. I do have a 4.0 but kept the 4.2 v-belt accessories. The part # I got is Duralast 922615. I also have a Duralast fan clutch on my Comanche and it also does well.
'83 Eagle SX4. 92 4.0 fuel injected, T5, NP229, '01 Dana 35 with Detroit Truetrac 3.54 gears.

Thanks. The hottest I've seen is 230 after sitting in almost the same spot for probably 5 minutes. I think that day was 101.

I think I got mine from NAPA several years ago, they offer both thermostatic and centrifugal versions, not sure if one might be more "heavy duty" than the other.  They also offer spacer kits, which might work as a clutch delete?  Seems to me i have seen universal spacers available on the internet.  Good luck!
