Re: Surprising source for ATF+4
 

I have had refrigerant in the system in my 1989 Suburban for three and a
half years now. I ascribe this to getting fed up with incompetent "air
conditioning repair" shops, and replacing all the hoses, compressor, O-rings
and refrigerant myself. I don't see how they can "reformulate" the molecule
without renaming it, but after working at Microsoft I learned that you don't
trust industry or government.

That must have been a BIG change to no longer require PAG; 134a is
extremely corrosive. I wonder if they also lessened the toxicity?
Morbidity studies I've seen indicated that a fatal dose can be inhaled
within 30 seconds inside a closed automobile should an evap core breach
occur. You'd think that the liability from this alone would cause changes.

Yeah, I do the same thing. Replaced the compressor and reciever/drier
myself, too. Got the compressor from a well-reputed salvage yard, and
got a goody. 'Course, with mine being nearly 15 years old (since last
rebuilt), I figured most any I got would have been rebuilt since it
was. Love those old upright Yorks-they last forever!
