rid myself of cycling

helpful55 on Sat June 28, 2014 9:12 PM User is offline

Year: 1984
Make: Buick
Model: Regal
Engine Size: 350
Country of Origin: United States

I have an 84 Buick Regal and I have always despised the GM cycling system with it’s click/rattle sounds and especially since I have a high performance engine I don’t like the varying idle speed it causes. I would like to go back to the older expansion valve system. Would I likely be able to keep the current evaporator, use an older expansion valve and dryer and make this work? I can do the adaption and hose work. If this is feasible I would have to find out what exp. valve would work. I also would like to use a Sanden 508 compressor. Would that be a match to the system needs? I realize that this will likely use more fuel but that is not real important. Thanks for any info.

You will still need a sensor type switch to cycle the compressor. A TXV will regulate the amont of refrigerant in the evaporator but will not stop the evap from freezing up.

Use a V5 / V7 GM compressor, and a TXV. No cycling. OEM mounts for some GM engines.
