    How do you guys deal with the old R12 freon problem? I need to charge the A/C of my TR and obviously R12 is almost impossible to find anymore. Is the only option upgrading the system to R134? Some people say that you only need to drain the system and add the new R134 freon, other say, that the process is much more complicated. I also hear, that you should never buy an aftermarket dehydrator filter, as most of them are not good quality. Not sure if Ferrari still offers OEM one though...

    as Prof.Irwin Corey used to say : "i'm not sure how it's done, but it's doable anyway".

    I was advised to keep the r12 if you could get it, it works much better in our marginal Ferrari air conditioning systems than r134, if you switch to 134, you have to change out hoses seals blah blah blah blah blah.
    I had a new AC compressor installed in my car during my recent major, and with r12 properly filled I'm getting 39° air out of my center vents, pretty good for an 1988 Ferrari.
    I managed to six cans of r12 on Facebook marketplace over the last year or two, I keep them in reserve for when I need to recharge. Usually available for about $50 each.
