High Pressure Line Many years ago I picked up compressor fittings from Docs Blocks just before they went out of business. I got both straight and angle/tube adapters and ended up using a combination: straight on the suction side and right angle on the high pressure outlet. Unfortunately the right a...

Thanks for the info 71403. Out of curiosity, do you know what the ECM does as an anti-slug routine?

Liquid Line Last night I loosely mounted the drier and started looking at liquid line routing. I was happy to see I should be able to route the line tucked inside the fender and out of sight by using 45 degree fittings on either side of the drier and a 90 degree fitting at the TXV. http://cjnn.xtre...

DEC PAG explanation https://www.autoacforum.com/messageview.cfm?catid=20&threadid=17571 For heater valves on GM stuff I use a vacuum unit, like the AC Delco P/N 155536 It was used on G vans, and P vans from 1990 to 1996. Thank you for both suggestions! I will look into these.

Here is a look at the exit of the POA valve showing the adjustment screw and lock nut. http://cjnn.xtremefabricator.com/images/LY6swap/ly6swap1417.jpg Can someone confirm if the threads are standard direction? i.e. I would turn the lock nut counter clockwise to unlock. Also which direction on the ad...

POA Valve Testing The POA has followed me in storage for the last twenty years, always kept in a ziplock bag in a storage bin of parts for the Nova. It's been moved dozens of times and it's sort of a miracle I haven't lost it. For a long time I was dragging around all the AC-related parts including...

History Detour I have had my car for 20 years now. Back in 1998 when I first got it, the original engine and AC system were fully connected, although I don't know if the system was functional. Here is what things looked like way back then: http://cjnn.xtremefabricator.com/images/psnpics/engine1.jpg...

Thank you bohica2xo! Can't tell you how much I appreciate the input. Yes this was a long time in the planning. I bought the docs adapters when I first got the compressor because I was aware they were going out of business and they were liquidating supply. However at this point my timeline is within ...

Suction Hose I have been sorting out fittings and hose ends to plumb the system. One place where a standard fitting poses a problem is at the exit of the POA valve. This joint is a #12 o-ring, however the standard size now used for the suction line to the compressor is #10. I needed a 180 degree #1...

Be gentle with the schrader valve on the oil return line at the POA body. I was thinking to just leave that valve in place. I worry about damaging it while trying to remove and reinstall. Is there any reason to remove it for flush or test? If not, I will leave it undisturbed. The 26 psi adjustment ...
