Yes and when that was done on my Saab, it was never as cold as with the old gas. I wonder if changing some other parts makes it work better?Our son had a very early 124 with AC running on R12 refrigerant. It was subsequently converted to R134-a. As far as I can remember no parts were replaced but it did require flushing and different lubricants to be inserted.
