AC compressor delete options?

The A/C compressor in my 93 parted this cruel world many years ago and I have no intention of replacing it. Its nothing more than a dead-weight idler pulley. What are my options to ditch it completely? Does anyone offer a pulley/bracket or other apparatus to mount in place of the deceased compressor?

Yes they do. It's a very common mod. Dorman makes one that's $28 + shipping from RockAuto. Look up "AC Compressor Bypass Pulley".

2 options

remove the compressor and get the bolt in pulley and use the stock size belt or

remove or leave the compressor and use a shorter belt


if you want the motor to run way cooler, remove the condenser too

I removed the compressor and did a shorter belt

I dont know how the 93 differs from the 96 ZJs, but I ditched my AC, and AutoZone didnt have a belt that bypassed the AC (in their system anyway). Upon doing some research I found that a 79.5'' belt wrapped around everything MINUS the AC compressor. The pulleys were about 30-40 bucks from what I saw vs. a ~10-15 dollar belt.

Aaron-- Are you absolutely POSITIVE on the length of the shorter belt at 79.5"?? I'd much rather just go to a shorter belt than have to use a do-nothing pulley. How is the belt tension and installation with the shorter belt?

Whoa whoa whoa. I don't think it's 79.5". My whole AC system is out and I'm running an 82.5" belt.

I removed the condenser and put a PS and tranny cooler in its place.

McClouds, not sure if it matters, but the thread you linked discusses belt length for a 5.9L. Mine is a 5.2

I'm with AVR2...Buy the A/C eliminator pulley from Dorman products...That way you dont have to worry about having to remeber what belt you used when it comes time to replace it...and for the money they want for those, its not worth the headache to trying to figure out the correct length and routing of a different belt...and don't forget that if you do it that way, to make sure the water pump turns the correct way when your done..

Removing the compressor shouldn't confuse anyone as to the routing of the belt, there would simply be one less pulley to wrap around. Everything else would go the same direction and wrap around the other pulleys just the same.

There's a picture under the hood showing the belt routing for no compressor... I have faith in you guys. You can figure it out.

Those dummy pulleys are terrible quality. They're flimsy and mine squeaked out of the box. I threw it away and got the shorter belt.

As did I!

Nice having a little room in that area isn't it? Summers are hot here tho is the downside.

Makes sense. The 4.0 does use a shorter belt.
