The problem is R-12 is too expensive ($37/can at my local mcparts! It was $20 last year) and R-134a doesn't work.


Doesn't work????
I must be the only one having any luck with R134a conversions. I have it in my 67 200d and my 74 280 done my old 77 450SEL, and to many other makes and models to list.

...And don't even go there, because my climate is HOT! 95+ most of the time here in Orlando .

I have a feeling that many of the DIY'ers and Pro's have indeed not preformed the conversion correctly by adding too much R134a to the system.

All I know is that it works for me....your mileage may vary, plus tax....
