What is R124 vs R134 refrigerant? 700

posted by  someone claiming to be geekdoc on  Thu Sep 12 15:57 CST 2002 [RELATED]

My newly acquired 780 cam with a sticker showing a conversion fron the old R12 to R124. My research on the net shows this to be another refrigerant but I have no idea whether R134 can be used in the same system or do I need new orifices?
Any ideas?

If it was converted "properly" you likely need new charge ports. The HCFC 124 fill ports are likely associated with FRIGC, Hot Shot/Kar Cool/, Chill-It/Autofrost, etc. One of them. R134a would be a different charge fitting. you might have to have the system checked out at a shop to find out exactly what is in there. I don't think that HCFC 124 by itself makes a good car refrigerant. It probably has a brand name somewhere on the conversion ("probably") but if not, a shop should be able to tell you what the story is.
