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.

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.

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

Like I said, I lucked out with the manifold thanks to the extra fitting someone added in the past. And all three bolts are 19mm, and I had no issues using a 3/8" ratchet and 19mm socket on all three. A 10mm deep socket on a 24" extension makes quick work of tensioning the belt.

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).

The account manager is so hungry for my business he will match any online price that he can verify, and will beat any commercial desk price by 5-10% without verification. Competition is fierce.

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.
