How easy is it to convert GM R12 AC to R134a?
Daniel Roberts
I have an 88 Chevy Caprice Wagon with the VIN Y olds engine.
Question is..
I am thinking of converting my AC from R12 to R134a.
My mechanic wants about $200 for the job. This seems a bit much to me
since i see kits for $65 or so.
My question is..how easy is it to convert my system from R12 to R134a?
I have an Harrison Compressor.
Does R134a work just as well in such an old system as mine? Should I
have my mechanic perform the conversion and then I can worry about the
charging from then on?
Have any clue how much a rebuilt compressor would cost for my car? I
think my compressor might be going bad.. Know of any reliable source of
rebuild or used compressors??
Thanks for the help!!!

$200 sounds like a "minimal" retrofit, and that can't include a new or even rebuilt
compressor.
Here's the legal minimum: recover R-12, add some POE compressor oil, change/add fitting
adapters, add high pressure cutout switch, evacuate systema and check for leaks, recharge
the system, perform final leak check and install the R-134a retrofit label.
However, that does not include flushing the system and changing out the
accumulator/desiccant, both of which should be done.
But yes, if you are going to keep the car for a while, change it to R-134a now, when it
needs a repair...although some noisy compressors will last for quite a while.
