Thanx for all the kudos.
Darrel, I converted to R134. Everything is factory except that I had the
POA valve adjusted for use with R134. It was done by the big A/C Co
(forget their name now) who are in Tampa. They cleaned, rebuilt (whatever
that involves) and adjusted it for 134. Many people recommend changing
the condensor to a parallel flow unit, but I think with the small cabin of
an el camino that may not be necessary.
I bought a vacuum pump off eBay. Expansion valve, dryer, o-ring kit,
nylog ( thread sealer), system flush, and system oil from ACKITS.COM and
learned from the forum at ACKITS and other internet sources.
The factory system used 60 ounces of R12, and experts recommend 80%
charge of 134. I was shooting for 48 ounces,. Stopped at 42 and have
driven it with that. This weekend I'll put the gauges on, and post the
readings at the forum at ACKITS. I don't have enough experience to
determine if the charge is "right" but someone there will make
recommendation.
Anyway, its not Rocket Science. I might be singing another tune if I
had problems, but so far I'm happy. And yes, just in time for winter, but
come spring (and spring comes early in West Texas) I'll be ready.
