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.

Maybe 10 min to get the bolts started and the manifold on. But tensioning the belt and tightening all the bolts alone takes at least 10 min. Add more time to find just the right wrenches to swing in the restricted spaces, unless you just did one the week before and remember.

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 http://www.peachparts.com/shopforum/diesel-discussion/387054-4-seasons-remanufactured-r4-compressor.html

There are different "wholesale" accounts. Getting a discount off retail from McParts is not a difficult task - even when buying locally. Many parts sold on Ebay require importers pricing to be competitive. Ebay and PayPal take 12% off the top. Subtract 12% and shipping and the actual part is priced below local jobber cost. The major cost on many parts is shipping. A fender is a good example and can be bought for less than it costs to ship. Obviously shipping is never "free", simply built into the price.

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'.

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?
