A/C refrigerants ... r-12 to r-134a or HC

[Roa, Greg]

Ahhh, but this should be not an issue.  You are supposed to only use 80% of the volume of r-134a to compensate.
As a side note, mine works fairly well after a conversion.  My compressor is weak, as shown by my gauge set, but even so, I get vent temps in the mid 40's after a few minutes.

That said, when mine ceases to work, or when I do a turbo swap, I'll likely swap my york out for a sanden.  I'm not at all impressed by the york's lack of smoothness, and the huge power sap that it is.  It does cool the car though, so I can't complain too much.

The york compressor is still used in r-134 applications on certain large trucks(freightliners), which says to me, that in a properly designed system, the york can work with 134a.

Good Luck!
