Another AC thread
For 3 glorious weeks I enjoyed the 60ish degrees pumping out of my dash vents to beat the 100+ AZ summer. It only cost me a compressor and a belt to get there after years of non functioning cool air. Then a few days ago leaving lunch the relief valve at the back of the compressor let go, I shut down the AC, cloud stopped, and rolled it back to the shop.
After googling a bit i first thought there may be something in the line or orifice tube causing the issue. I replaced the lines, orifice tube, acumulator, and all fresh orings this afternoon. The relief valve seemed to reset itself, held -27lbs of vacuum thru a 5 minute test, took a recharge of the 3.1lbs I found to be common and used on my last charge and fired up the truck to equalize.
Boom! 90 seconds later and im pumping freon into the clouds like the EPA owed me money, right out of the relief valve again.
Any ideas before i yank this new compressor out would be awesome. I run the a6 comp on r134a in an 84 c10.
