    R12 R24 Air Conditioning Specialist: Intocool in Essex

    I've been posting detailed progress about my W123 OEM restoration on Peach Parts I purchased my '84 300D knowing that the AC wasn't working. It hadn't worked in 5 years or more, around when R12 became impossible to procure. So naturally, when I pulled into Intocool's vehicle bay this...

    Air conditioning R12 to RS24

    Hello all forum members, not sure if I've posted in the right place but I just wanted to share an excellent a/c engineer's services. My 1991 560SEL suffered the usual nonsense from the previous owner about the a/c just needing regassing to magically come to life again. Against my better...

I'm hoping that as long as I run the a/c periodically to keep the circulation going and the seals lubricated, things will be OK.

    R12 refrigerant conversion to what?

    What is the current acceptable gas that is used as a replacement for systems running R12a? I mentioned R49 to one local firm and they said no to that one. They said they used R134a in conjuction with a special extra type of oil that sat on top of the standard oil. I was told that R18 and R49...
