All,

Anybody have experience with converting our cars' A/C system from R12 to R1=
34a? My 92's Zexel A/C compressor is growling and needs to be replaced. Sin=
ce I'd need to flush the A/C system for the warranty on the rebuilt Zexel c=
ompressor (Hancock Industries) to be good, I'm thinking that would be a goo=
d opportunity to convert to 134a. I'm wondering if anybody has actually don=
e this and would share their process/thoughts/results.

Thanks,
Steve Jacobson
