    My compressor is the original OEM R12. This cannot be recharged in my state anymore.
    I understand that they are kits to convert to 134A.
    My compressor needs replacement. Anyone has used compressors R143A in lieu of the OEM one?
    What have you used. If you rebuilt yours where are the rebuild kits available?
    the new one is $2K and add retrofit kit to that

    FWIW I have plenty of r12 if you want. Shipping is the hard part. Yes I converted mine to 134 probably a decade ago, before I got the r12. All you really do is replace the receiver dryer, turn the compressor upside down & replace with ester oil (IIRC) & pull a vacuum. I doubt the compressor is anything special & could be interchanged.

    Have you looked at a Sanden SD 508 compressor? There are plenty available under $250. I’ve used R152 as a straight swap for R12 in 3 vintage cars. Works great. It’s more environmentally friendly than R134, is cheap and easily available. But it is sold as air in a can for cleaning keyboards and such. Ultra duster industrial strength is the brand I have used, $28 for a 4 pack of 10 oz cans. You’ll need an adapter to piece the can and connect the hoses.

    Officially R134 is not suppose to work as well as R12. But the people that have done it that I know were hard pressed to tell the difference.

    Cheers Jim

    Thks Jim but I will convert to R134 as R12 is done and conversion is inevitable over time.
    My issue is really to get a new compressor that does not cost $2K. This price is just crazy. I am told that kits to rebuilt them are N/A.
    I will check the ref you gave me.
    cheers

    I have not actually replaced one, but if I need to replace mine I will buy one like that. The best I can tell that is a direct replacement. I do recommend checking their return policy and comparing it to the old one as soon as you receive it in case you have to return it. More often than not parts like this are standard off the self items. Looking at Sanden’s web site I believe the 508 number indicates the displacement so that will be the same, it’s the external features you have to look closely at.

    Note R134 and R12 use different oils. I would recommend flushing the system out on the car to clean out any residual oil out of the system before installing the new compressor with the new oil in it. You can buy kits that use compressed air and degreaser to clean out any old oil.

    FYI, my car has the sticker on the compressor, that is where I got the Sanden 508 info.

    Cheers Jim
