Taboo question!!

TRB on Sat June 06, 2009 10:13 PM User is offlineView users profile

OK I need to make the claim up front I do not condone this just asking a question for the experts!

We suggest adding some R134a refrigerant to test for leaks. This is suggested even when said vehicle will be using R12, but the normal response is "do not run the A/C" just use the R134a to create enough pressure in the system to check for leaks. So here is my Taboo question, what if the system was ran and fully charged. We say you contaminated the accumulator/drier and the oil at that point. Been a long time since I read the fine print on what the EPA has to say about this. But my question is if no leaks were found and I reclaimed the R134a then pulled a vacuum and charged with R12. Do you really think this will damaged the components with what might be a very small trace of R134a molecules left in the drier and oil?

Again I stress follow normal procedures! I bring this up only for debate!!!!!!!!!


When considering your next auto A/C purchase, please consider the site that supports you:

I don't think it will harm it at all, I even use R22 sometimes. But don't run the compressor still stands..

Naw it won't hurt nothin. Since refrigerant boils at such a low temp any traces of it are gone with in a few minutes of starting the vacuum pump.

Won't hurt it one little bit.... I regularly ue R134a to seek leaks in R12 systems.... Seems that I'm the only guy round here who'll work on an R12 system as all the garages here hav shiny new processor cotrolled management stations that have a database of charge weights built in

Never knock on deaths door... Ring the doorbell and run away, death really hates that!
