The a6 will "lock up" and act like it's hard to turn, and your belt will squeal like a pig.

I went through 4 of them over the years on various trucks before I concluded I was wasting my time and went with a new aluminum a-10. No more belt squeals, no leaks, no problems. A rebuilt a-6 will fail, it's only a matter of time. They also leak at the front seal. I will never use one again unless it's the original one on the truck from the 70's and still functioning.

I restored the factory AC in my 68 a few weeks ago, a-10 compressor and r-12. 36 degree air idling at a stop light in 100 degree heat without missing a beat.

I almost upgraded, cold instead of cool would be nice for sure. But decided to cheap out and go through the system when I pull the engine. I just got rid of the original A6. It was locking up and squealing like a stuck pig but was blowing pretty cold, it finally thew a belt. I put on my rebuilt junker and the compressor looked like it was locking up, like the old one... I blamed you and all your anti A6 posts.... But I tightened the belt and it's been OK... but now that I said that it will probably spit oil next time I turn it on!!
