My compressor seized up today. Made some great smoke on the highway. Do they reproduce these. I'm looking for something original, or at least close to it.

No worries Christian, that GE2013 trip looks great! I hadnt even heard of it - but I shall keep it in mind nearer the time..

Just my experience with R134A in my climate control 64. Did not like it, changed it back to R12. Can still find R12 at the swap meets for $15-20 per can. R12 does run colder than R134A. Locally in Ca as you know we are the whipping boy for environmentalists R134 is about $20/can plus $15 deposit which you loose if not returned in some time period guess that discourages stockpiling, then you have to buy an adapter to fit your gauges as they changed the fitting on the can Sooooo for me the R12 was a better and cheaper choice.

Thanks Paul. It's a completely rebuild A6 compressor. Even my original system in already converted to R134a. I'll use PAG 150.
So my AC will be ready for the trip to the GE2013 in Holland (http://www.cadillacclub.nl/ge2013/). Will you be there too?

I love this forum :)

Made a typo I meant pag 150 I'm running not pag 160 lol
Comment by Paul on June 17, 2013 at 4:23pm
Hey Christian, if you are going with r134a and an original a6 compressor, the. Yeah go with pag 150 for sure. However if your are going with the s6 ( a6 replacement go with pag 46. Hope this helps! FYI. I've been running pag 160 in my rebuilt a6 and it's running just like it should do. Do make ire you clean all the components though, flush through with a good strong mineral spirits, I used isopropanol. I flushed the condenser, evaperator and replaced the rubber hoses. Refilled all components one by one by the book with the correct amounts of oil. Vacuumed for one hour and charged. I get at least 40f at the vents.

Thank you for your help, guys. Paul, are you sure PAG 150 is the correct lubrication oil for the compressor, filled with R134a?

The Ac system once opened ,should be evacuated by a machine to remove all moisture from the system ,from what I have learned havng my changed over by a shop

So not sure this can be done without the correct tools

 Some R-134a freon cans come with oil in the cans

Comment by Paul on June 17, 2013 at 9:18am

as you will be flushing the sytem due to contamination - i would change all orings and use pag 150 oil on an a6

Comment by Paul on June 17, 2013 at 9:15am

I replaced mine with a remanufactured original A6 compressor from rockauto.com  - $106.79

Replaced all o rings for r134a and rebuild stv with parts from old air products - also they rebuilt my original drier.  filled with pag oil.  works a treat :)

Hi guys, I have to change my compressor too. Now we can't find out what lubrication oil should be filled in the compressor when using R134a. Does anybody know it? When using R12 the manufacturer only writes 'mineral oil'. No information about using R134a and no specification like PAG-46, PAG-100 or PAG-150 etc. But in the paper which comes with the compressor, R134a is approved instead of R12.
