A/C Clutch noise

May 02, 2005, 01:07:05 PM

Greetings all,
My 88 5.0 cougar has a squealing noise coming from the AC compressor. It does not make the noise when the A/C clutch is engaged (spinning) The A/C works fine but this noise can't be good, or cheap. Can someone please advise a solution? Can I replace the belt with the one that is "sans A/C" Thanks

I'd guess it's the bearings in the clutch. The bearings are only in use when the A/C compressor is off. When it's on the bearings inside the compressor that carry the load.

Yea I replaced the idler bearing on my AC compressor a couple of years ago... Had to get it from a bearing supplier(or order it from Ford), was about $30... :eek:

Thanks Thunder Chicken and Turbo Coupe 50. Does this job require any special tools? The drawing looks like the pto for my tractor, so I'll give it a try. Hate to try to make it through a Texas summer w/o a/c. Thanks again

Even I say "gotta have my AC" way up here. I guess I don;t know what I'm talking about compared to y'all down south.

Naah, I'm sure plenty of people up north feel the same way about A/C as we do. Just seems like it's optional to a bigger percentage of ya up there. No need to get touchy about it. :D

When my fiance moved down here from Chicago, she said 78 was a pretty warm day to her.. but 78 is what we keep the house A/C set to most of the day. At first it might've been a little uncomfortable for her, but now she's used to it. It's just getting used to a different scale of temperature. Anything under 60 degrees is cold to me, but I'm guessing most of you would laugh at that sentiment.

I probably put my heater on at temperatures that you guys would laugh off, and you probably put your A/C on at temperatures I'd laugh off. I guess A/C would seem as odd to me up there as a heater down here would seem to you. But if we both use 'em, no big deal.

Next-day edit: Come to think of it, why am I playing peacemaker over something as trivial as a statement about the weather? If you have an issue with it, that's your problem.

I keep my room around 50 in the winter and around 60 in the summer. I cant sleep if I am all sweaty. I block off the heater vent in the winter. I dunno if I can keep my "new" room that cold in the summer now. Before I lived in the basp00get, and we had central air and a swamp cooler. It would be 80 or so upstairs and 60 or so downstairs in the summer.

I keep this window A/C on 75 all the time, and the central A/C is on one of those programmable thermostats.. 78 during mid-day, then it drops to 77 for morning/afternoon, and 76 at night.

Tried running the car A/C yesterday.. on max A/C and one notch up from minimum on the fan, it cooled decently.. but I can tell it needs a recharge. I'm wondering if a guy I know from high school who owns a car repair shop would take a couple of A/C gauge sets in trade for some A/C work on my daily. I gotta do something before the worst of summer arrives. (only in the mid-80s now.. add another 10-15 degrees to that)

Gotta replace that alternator, too.. running the A/C fan near killed the battery yesterday. Not generally a good sign to me when I put the 2A/6A charger on and it reads over 2A on that setting.

You will need the A/c clutch remover installer tool. It is preesed on like the PS pump pully. only this one the puller threads into the front of the clutch. then you turn the center bolt to remove the pully. I haven't done it but i've seen it done. Looks like fun. LOL

My pulley just popped off with a couple of good tugs. Depends on type of compressor, but on mine the bearing is just held in with a clip. Was easy to knock out, and used the old bearing as a driver to pop the new one back in place.

it could also be a backwars thread, That is what took me so long to get a new pulley for the belt tensioner. My belt tensioner was seized. The ball berring had gone bad. Prolly since I had gotten the car. (I have only added about 1,000 to 2,000 miles) I threw the sepentine belt into the fan while driving on the free way. I heard a lound clunk, and then my altenator light came on. I figured that it was a battery cable that got eaten by the fan. I got off of the freeway at the next exit and drive about a block to the auto zone. $35 for a belt, $20 for a plastic pulley(couldnt find just the berring) and I got to switch the belt out without tools(pinched my fingers a couple of times.) started it up with the hood up and saw smoke comeing off of the tensioner. Had to wait 1 and 1/2 hours in front of auto zone for my dad to bring me the tools. He was going to the junkard the day before. The tools are normally in my car.

The compressor is a Nippondenso. The clutch came off easy enough. I pulled the clip but the pulley won't budge. I noticed the pulley is cracked in a couple of places. I read in another thread about a pulley than can be used instead of the a/c compressor. Does anyone know where I can find one?

sometimes I forget that I'm not at http://www.turboford.org I was talking about the HR980 comprssor that came on the 2.3's and some of the 3.8's Those work as I said or at least the two I have do.(they are old ones though)

I should have paid more attenion to detail. Any how I did get the A/c converted and working in my 84 Turbo coupe. :D Now It's not so bad on the hot humid days here in the Ozarks.
