1987 Eagle Limited AC Expansion Valve
« on: February 17, 2018, 03:10:38 AM »
My mechanic says I need a new expansion valve. The replacements we can find are 90degree set ups and he says mine is straight (180 degrees). I can not locate any straight ones. Any help greatly appreciated.

Wonder what you have?   The AMC parts book shows both the factory and dealer-installed A/C systems to have valves with fittings 90-degrees from each other.   Have a pic of yours??   That may give us a clue.   Just for reference, the factory part number for the factory A/C valve is J3728053 (unobtanium from any of my usual sources).   The dealer-installed American Air version is J8126987 (that one is easy to find - crosses to Four Seasons 38608).   Good luck with it.

Thanks. My service manual also shows the 90 degree. I have asked him to pull it out and get me a picture and any part numbers on it. Thanks for the cross references.

  • You can do it right, or do it twice.

I know this thread is old, but I found it searching for an answer to the same exact problem. I have heard varying stories, but some say that non-factory A/C sometimes had the straight expansion valve. Others say that they are from another AMC product, and towards the end they were running out of parts and just used whatever was lying around that they could make work.

There are two issues...the straight through Expansion Valve is an O-Ring connection, while the 90 degree is a flare. The second is hose routing. I was looking into converting from straight to 90 degree, and while possible it would take a ton of work (rework of the heads on the hoses as well as cut / weld different bends into the evaporator.

But I found a solution.

Old Air Products -

Part Number 25-8731.

Hope this helps someone! It took me a few weeks of research to find this and figure it out.
