Nope, I have no idea what that is.

Doesn't matter anyway, as the AC Delco reman compressor was bad right out of the box. Pissed away $18 worth of Enviro-Safe, too. New compressor gets delivered tomorrow, and I will be charging the system with R134a as I can't find any ES stuff locally. Too bad for my brother-in-law; I was trying out the Enviro-Safe stuff since he lives in Phoenix. Hopefully the 134 is cool enough for his tour of NY and the eastern seaboard and he can find someone to replace it with an R12 substitute in Arizona.

I have had the exact same R4 problem years ago, it is a common theme with them. It was the "last straw" for me, and was the last R4 I used. Good luck with the replacement, you will need it.

I hope you read the AC thread in my signature.... before you invest more time and money...

IF you have one of the later R4 compressors and follow the AC rules.. you should be just fine... don't let ROLLGUY's negative comment affect your decision ... millions of them have been used with R134a just fine in other vehicles..

My comment was not meant to be negative, I was just sharing my (same) experience with an "out of the box" bad R4. What I did NOT share (but will now), is the many "out of the box" bad R4's my local A/C shop has had to deal with. I was offering "good luck" to the OP, because maybe he will have something that has alluded me when dealing with these compressors. As always YMMV.

Curios what was bad about your AC Delco reman compressor? What's the p/n, brand etc? Did it have a small or big clutch? Stepped ports or o-rings on the manifold? I just put a reman in my 85 and it's working ok so far 4 Seasons remanufactured R4 compressor

4 Seasons reman'd for AC Delco, came from WorldPac, p/n 15-20516, with o-rings and large clutch. I had a bad feeling about it when I drained the initial oil charge and there were bits and pieces in that oil. The compressor ran for about 10 seconds but stopped actually compressing anything and just made a loud rattling sound whenever the clutch was engaged (and for a few seconds after the clutch was disengaged).

Did you flush before installing the new compressor? Chances are the "bits and pieces" (some unknown quantity) are still in the system if no flush was performed. Just sayin'.

Yep, this ain't my first rodeo.

I spoke to 4 Seasons tech support about their reman and new R4's. They supply them to quite a few outlets such as PepBoys Factory Air, Autozone, OReilly Everco (not sure), Advance Tough One and others. The compressors are from the same assembly line in Mexico. Sounds like yours may also be from the same assembly line. Did you flush the system before installing the reman? What did the flush look like?

I did, and it was just old brownish oil, most of it in the evaporator. No chunks or bits, and I even cut open the old dryer and found nothing suspicious. I was just a bad compressor. They didn't do too good of a job cleaning it before painting it, either. Chunks of old dirt and grime kept coming out from the nooks and crevices.
