jimscat Posted August 5, 2005 Share Posted August 5, 2005 Hopefully someone can help. I have a 93 Legacy wagon 2.2 146,000 miles and I just replaced the compressor. I was able to use a zexel off a 95. Bolted up identical. The AC works awsome, but know I get a squeel. Sometimes breifly and others it takes a couple of minutes. My question Knowing that the clutch is magnectic, could I possibly have a weak altinator? not allowing a full grab or would it be a clutch going bad? What I have already done Replaced shot compressor with one from a 95 new belts - adjusted a couple of times, thought I had it, was real bad, now intermittent after getting system filled had a problem getting power to the compressor, jumped it and worked fine, played with the relays and really don't know what I did, but it works. What should I have for amps / volts at the compressor and relays coming from the alt? Any ideas? Thanks, Jim Quote Link to comment Share on other sites More sharing options...
Olnick Posted August 5, 2005 Share Posted August 5, 2005 Just an offhand thought, but could it be the other belt--the alternator/power steering belt--that is causing the squeal? Quote Link to comment Share on other sites More sharing options...
jimscat Posted August 5, 2005 Author Share Posted August 5, 2005 I have had someonbe assist me and its deffinatly the AC squeeling. It does it only on start up of the compressor. Quote Link to comment Share on other sites More sharing options...
crauch Posted August 5, 2005 Share Posted August 5, 2005 If your belt squeals it is not tight enough or is is worn. I had the same problem after I replaced the alternator on our '99 Forester. It takes allot of tension to keep it from squealing. I have had someonbe assist me and its deffinatly the AC squeeling. It does it only on start up of the compressor.

jimscat Posted August 5, 2005 Author Share Posted August 5, 2005 once again I have loosened and retightened the ac belt, checked all voltage from the battery (car off) the relays, and the output at the compressor plug. All are 12-13 volts. The guy I had helping me noticed that it appeared to be the whole belt slipping so now I am going out to check the adjustment pully for any resistance Quote Link to comment Share on other sites More sharing options...
jimscat Posted August 6, 2005 Author Share Posted August 6, 2005 thanks for the help. I finally found the colprit, the adjustment pully was kinda gummed up from many yrs of no use. Cleaned and lubed, no more squeel I hope Jim Quote Link to comment Share on other sites More sharing options...
