Ideas for an a/c with a serpentine belt 1981 4.2 cj7 258

I was reading several threads about installing an a/c in a 4.2 cj7. But, I couldn't find any with a serpentine belt. What I have is 1981 4.2 with a serpentine belt, I'm looking for a complete unit to install into the old cj. I've looked at Collins Bros and JeepAir, but theirs is just for v-belts. Anyone have any ideas or run into this before? Thanks

Maybe check for YJ 258 ones?

I had thought about that too. It seems like it would work, I had called Jeepair, I asked lady answering the phone about it she said they didn't have anything that would work. So, I thought someone on here would have run into the same problem. Thanks

Only difference out of the whole set-up would be the ac compressor clutch.
All 1981 and later CA models were serpentine with Sanden compressor.


Worse case...?....buy one of the kits and change the Sanden compressor clutch?

California models used serpentine belts and AC. The donor block I rebuilt was from an 81 originally built for California and it had AC and a smog pump. The pump is long gone but the AC compressor is now being used for OBA. The AC was a Sanden pump if that helps.

Opps. I should have read chromegrills post before I hit send.

Bump - I called Sanden and they said they wouldn't have a compressor that would fit on a 81 cj7 4.2 258 with a serpentine belt. Anybody else have an idea as to what would work. I would like to keep it a serpentine, and not change to v-belt. Thanks

It is a 4.2 and they made them with serpentine belts up to 91. Same setup as far as I have seen.

Thanks, when I called Sanden the tech support guy said he had ran into this issue before, but he never could supply the compressor. He said some guys just made something work by shimming, he wasn't too sure. I was looking on their web site and all the 4.2's that they have for wranglers are v belts. I did find that it has a SD7 Direct Short mount. I'm going to look further into it, found some conversion brackets called a york to sanden claw d36. Maybe that will lead me somewhere.

can you not just change the v belt pulley out for a serp. belt pulley? using the same compressor.

Not easily or cheaply. You need a different water pump and fan setup as the serpentine has those going in reverse. Then you either need a new PS pump or you can attempt to change the pulley, same for the harmonic balancer and alternator.

I would call jeepair.com there customer service is pretty good. if any one knows how to make it happen they will. they are the original makers of the a/c units. when I installed the 30 year old system in my jeep, it still had the contact info sticker on it. cant remember if they were a diff name or not. they were very helpful just over the phone. have to say, my little unit in the jeep actually works pretty good.
