I have a 1991 Camaro RS with the 3.1L. The AC system has been converted to R-134A. I just recharged the system about a month ago and now the compressor won't work. It could quite possibly be the clutch, but I'm not too sure. Does anyone have any information on prices for fan clutches and/or compressors for a 3.1L? Thanks.

 

Go to www.acdelco.com Punch in all vehicle info and it crosses almost every common part for the car to a Delco number which you can then use to browse for prices. They cover all HVAC components. 134 and a compressor problem, where have I heard that before. I would rather pay $150/lb for 12 than use that crap. Even the new cars designed for it are having all sorts of A/C problems within a short time. My 98 lost it's charge enough to keep the comp from coming on. They claim that up to a 1/2lb per year loss is acceptable. I just put a 1/2 lb in my 89 last year.

 

Most r134 systems only take 2 lbs. There isn't any loss allowed with freon and that wouldn't matter if it was 12 or 134. New systems are all designed with max cool condensers which is how they get the smaller systems to fuction so well. In most cases you could easily convert a r134a system to run R12 and the only diffrence is the cost of the freon. Switching to 134A from R12 is something I always opposed untill too many of my R12 service/repairs had a unforseable failure in which the R12 is lost. I found out quickly that the system resonds perfectly if it's done right. I do a conversion a day this time a year. Most pressures are almost identical between the two when flushed properly (The big key ). I'd have to say GM has the biggest new car A/C problems as of now unfortunatly, atleast in my area

 

Thanks for the information guys. I do personally like the R-12 better, but somehow these environmentalists seem to ruin things for the rest of us...I'll check out that website and hopefully find what I need. Thanks again.
