FYI, I just completed a R134 conversion and it worked rasonably well. 8) I did not replace any components, since the system worked (sort of) on 12.
All I did was had the system pumped down (to be green and legal) and then I evacuated it, let it stand to make sure it held, then charged w/ R134.
The Low port is a bear to get to, and it gets very tricky to remove and reattach the hose, it is adjacent to the turbo, and I have a couple of minor burns to remember it by. :bad-words: I would suggest a charging manifold if you can get your hands on one, I only have guages separate.
Any way, we just went through a weekend of 100+ and it cooled as well as any other car on R134, :rock: seems none of them get fridgid real fast like the old days of R12.
My research finds that if you have a problem with your ac that caused a loss of gas, FIX IT FIRST! :!: The molecular structure of the R134 is about 10% or so of R12, so if there is even a hint of a leak for R12, you'll have a disaster w/ R134. Also, if it has been open to air for a while, be same and replace the acum or drier and evac it, lest you'll get corrosion later down the road and that's big time 'cause it'll destroy a coil.
Hope this helps keep em coolin, spoolin, and cruisin! :usa
Good info, knowing converision will work, 5 years ago i replaced
evaporator and Accumulator, new accumulator has low preasure fitting,
it was worth it just to avoid hooking to fitting next to turbo!!
I would have recommended an accumulator change, new desicant
cann't hurt, better suited to r134. I topped my r12 system off with single can 134, just cause i ran out of r12, has been cooling great and reliably for 5+ years.
