Hey people,
Coming on Summer time, and with the thought of the meet this June, I've decided to get my A/C system refilled in time for the event. (Hopefully expecting some lovely warm and sunny weather over that weekend)
Anyway, i'm aware of the old arguments for and against R134a systems, and aware of the pitfalls and tragedies possible for converting an R12 system to R134a, or the alternative apparent simple drop in replacement RS24 for R12 systems.
Talking to someone who i was wishing to refill LEX, and having some backup experience of talking to people, it seems to be very difficult to find someone capable of, or even stocking RS24. My man, therefore, is suggesting, with his previous working experience on other vehicles doing the same thing, and being successfull, and still working many years later, to do the DeLorean with R134a and instead of the normal "PAG" oil, to use Ester oil, which is apparently compatible with any remaining R12 which "might" be left in the system even after a thorough cleaning and flushing, before refilling again with R134a.
Looking at a few websites, i came across this one, which seems to backing up his argument:
http://www.id-usa.com/how_to_faqs_retrofitting.asp#7
So my question is, what do people here think of this approach, and has anyone got any working experience of doing this with either their own DMC's or any other older vehicle? I'm inclined to trust this guy, but am seeking reassurance i guess. Looking at the website above, i'm believing that the whole argument of R134a eating through your R12 system components due to reaction, isn't entirely true, or has been mostly combated against with new techniques...blah blah blah.
If done properly, and thorough cleaning of the old R12 stuff is done, it sounds as though it might be ok to do....
Let me know people, i've got until June 3rd to make a decision whether to let this guy near LEX with his tools etc, or not. LOL!
(I'm getting the Civic done at the same time, which wont have a problem, hopefully, as it is obviously a newer R134a system from first build.)
