My POA valve is original. It is good, but should I replace it anyway since it is so old? I don't mean replace it with a new cycling type kit, I already know not to do that. Some times it is wise to replace a part while a system is torn down if they are old. Are POA valves like this, or if they are good, but very old, is it OK to reinstall it?
I do not think they are being produced. There are some companies that repair/rebuild them.
From your other posts, I know the plan is to convert this car to R134a. The POA valve needs to be calibrated for the different refrigerant. There are server places I know that can do this for you (maybe even AMA?). It would need to be sent in. While thy had it, any cleaning, rebuilding or anything else could be done. If a search was done, instructions can be found to do this yourself.
Good luck on your project.
I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!
Thanks for the response. I do plan to recalibrate the POA myself. I was mainly curious if a POA should be replaced even if it is good working order due to old age.
I doubt you'll find a new POA.
