Question A/C component question

So I started installing the wife mandated aftermarket A/C, and have made it as far as installing the new compressor, condenser, and belt. Nothing is hooked up and the compressor still has it's plug bolted in place. I started it up and started to get a squeak from the pulley/clutch area of the compressor. I can make the squeak louder or absent by pushing on the front of the pulley/clutch. I called Jeep Air, and all the lady said was to tighten the belt (I hope the product is better than the customer service).

The question I put out there to all my WF friends with A/C knowledge, is this part of a break-in period for the compressor clutch, and will it hurt the compressor to drive the Jeep even though nothing is hooked up (hoses, wires, etc.) I get about an hour and a half everyday to work on it while the kids nap, and its killing me not to drive it.

Thanks in advance.

The a/c pulley should freewheel when the clutch is not energized(pulled in). It is like an idler pulley right not. It should not squeek and you should be able to drive it.

I installed one of their kits in my sisters jeep(1991 Wrangler 4cyl) last summer.

The instructions leave much to be desired. Had to improvise on a few things. Have a lot of beer on hand and take lots of breaks. Trust me on that.

However, that thing blows out some cold air.

I haven't installed an aftermkt compressor (belt driven) for a long time, but

If the belt is tight enough and a fairly new belt (??)-then the pulley squeaking/squealing, with no load, means-it's not lined up EXACTLY and is not in direct line with the belt/other pullys-or possible internal lack of lube !!

Hard to tell untill you check the pully alignment !

Good luck

Thanks for the help, gonna check the alignment. Between the mounting plate and the compressor mount, it's likely there's some misalignment somewhere. If that doesn't work, I'll take a break, have beer, and start over.

I remember reading about energizing the a/c clutch and rotating the compressor pulley a few turns. I think it was in the paperwork that was in the compressor box. I know I did it on mine. If you end up sitting down and having a few cold ones, look for it.

Hope this helps.

Nothing in the paperwork about energizing the ac clutch. Gonna check the alignment as soon as I can get a kitchen pass. Did u take it to a shop to get a vacuum pulled/charge?

I do refrigeration service. I have all that stuff.

You should take it to a shop that you trust that does a/c work to have it leak checked, pumped down, and recharge.

I think in the box with the compressor was the paper that something about rotating the compressor to lube it. I may have just known that. Sorry, too many dead brain cells.

Thanks, there are a few A/C shops in San Antonio, some do installs so I'll start there. I read in the paperwork where it says to spin the pulley, but nothing about energizing the clutch.

I finally got into the dash and I'm finding that the directions left out a few things, a plug here, screw there. I just keep reminding myself of the $1K I'm saving...

I can't find the instructions that I used anywhere. I guess I did burn them.

My thinking on energizing the clutch is if it's not energized, the pulley freewheels. If it's energized, you rotate the compressor internals.

I did under the dash first, installed compressor, did the wiring, jumped out the high pressure control, turned it on to see if there was a electrical problem. When the clutch pulled in I turned it a few times in the correct rotation.

Good luck.
