You should have it professionally evacuated for several reasons. 1. R134 should only fill 85% of the volume of specified R12. You won't know how much remaining R12 is still in the system unless it is fully evacuated. 2. R12 Oil is incompatible with oil in R134 3. I have been told that the combination of the two results in moisture which will eventually ruin several internal components. 4. Evacuation is done under vacuum and therefore will make any leaks evident.
I was told most shops with the proper equipment will charge around $30-50 for an evacuation. It is usually performed for 30 minutes or more. -----Original Message----- From: [email protected] [mailto:[email protected]]On Behalf Of [email protected] Sent: Wednesday, July 10, 2002 9:39 AM To: [email protected] Subject: [A2-16v] AC compressor replacement... All, So my Audi needs a new A/C compressor. I can get a used one (with warranty) for $75, and R-134a conversion kits for $35. The system is still charged with freon, though. Now, my question is this: Can I just pop the valve on the A/C and vent the freon, then fill 'er up with the R-134a conversion? I _fully_ realize that this is a huge environmental no-no, but it would greatly simplify my life. Otherwise I'm going to have to pay $$$ to have someone take my freon out, install my new compressor, and put R-134a in. I may not do it that way, but is it a viable option? _______________________________________________ A2-16v mailing list [email protected] http://maillist.myip.org/mailman/listinfo/a2-16v
