Of bigger concern is the question of how much lubricating oil is left in the system.

I originally thought I could flush the system (as AC repair shops claim to do).

I am sure the AC repair shops do have the refrigerant.

Personally, I'd do what I could to use 134a, unless you've heard from better sources than I that it's OK in our Porsches.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hello all:
I live in Canada, and apparently, no R134a refrigerant is sold in Canada!
The Walmart website, states the following for R12 refrigerant, which is widely available in any auto store here in Canada:
Replacement refrigerant (Canada) for R134a and R12 refrigerants
Each 6 ounce can is equivalent to 17 oz. of R134a and 19 oz. of CFC-12
.
Using Duracool � 12a Refrigerant results in lower head pressures. Lower head pressures prolong equipment life.
I accidentally pierced the low pressure line; so, my system is completely empty. I have new pipes installed. The system is now vacuumed completely.
Any constructive comments in regard to filling the AC with R12, as opposed to R134a is appreciated.
Cheers,
Zack
PS. I HAVE read everything on the manufacturer's website!
http://www.redtek.com/win_12a_faq.html
The Duracool product is not R12, but R12a or R129 as listed in their FAQ. FAQ states it's a drop-in replacement for R134a.
As far as constructive comments for refilling your system, the FAQ has a pretty good procedure listed, due to the weight differences between the two products. Personally, I'd do what I could to use 134a, unless you've heard from better sources than I that it's OK in our Porsches.
I find it curious that you can't find R134a up there, since they obviously use it in new car production, and there are several US brand assembly plants up there that use it. Is it that you just can't find any, or it's illegal for a DIY'er to handle it?
WWest:
You posed an excellent question. In fact, I was going to do a new thread on that!
I originally thought I could flush the system (as AC repair shops claim to do). However, there is a very nice video by Scotty Kilmer that explains why flushing does not work.
Why Flushing AC Systems Does Not Work Anymore - YouTube
I now wonder if I should dismantle the compressor and drain it, or what?!
Cheers,
Zack
