Converting to current A/C refrigerant
I'm tired of adding $100+ of freon every year to my 1980 240D. To convert to the new stuff I have been given quotes of $1200-$1600 by A/C shops. Looks like I can get all the parts necessary for about $400 from Performance (including new compressor).
Where can I get detailed instructions as to what to do? It would also be nice to have a diagram. (I'll be damned if I can find the expansion valve.)
Has anyone done this conversion that can supply some input as to ease, pitfalls, etc.?
