Red Block Era Air Conditioning
 

Calling all Red Block Volvo owners still running original Volvo air conditioning: Either R-12 or R-134a. There’s a small pressure relief valve (Volvo 1323803/3522398) in the AC system, usually right front either just behind the bumper or below the radiator. Mine appears to be leaking and, as of yet, I cannot find a replacement. After replacing the compressor and retro-fitting the refrigerant I’d like to continue using the AC system. Have you experienced problems with this valve?
What happened?
What did you do?

NLA new. Never had a problem with that valve, must not go bad often so should be available used...

When I did my AC system over this hose had a replacement without the valve in it. I believe you can still get the replacement. Just do a search on volvo ac hoses.
