A6 in a CCOT system?

brimac50 on Thu May 06, 2010 1:19 PM User is offline

Year: 80
Make: Chevy
Model: 3/4T
Refrigerant Type: r-12
Country of Origin: United States

I'm considering using an A6 compressor on my 1980 3/4T Chevy, which is a CCOT system. It's my understanding that GM used these compressors on the "earlier" (73' ...) trucks. It's also my understanding that A6 clutches don't stand up well to constant cycling. So, my question is, ... what are the differences between the "early" system, and the later CCOT. Or, what changes to this 80' CCOT system should I make, for a successful A6 install? Always learning. Thanks for the assist.

I had a '77 K1500 GMC with a factory CCOT / A6 setup and it worked well until I sold the truck with about 150k on it. That said, I would probably rather try to retrofit a Sanden/Seltec on your truck than using an A6. Tim should be able to set you up with what you need. It will be smoother, quieter, and lighter than an A6 and definitely take up less space under the hood. You will need custom hoses either way.

Back in the late 70's and early 80's, we often would replace an R4 with a A6. The rear mount manifold was common and if the lines were long enough, we just ordered the A6 and fabbed mounts.
