r134 conversion
How can one tell if the AC has really been updated or not? I bought and '87 911 and the PO told me that the other PO had conveted the AC to r134. Is there an easy way to tell by looking at it?
Thanks, Patrick |

If the PO that did/had the conversion done was on the ball a label would have been placed in the engine compartment to identify that it had been converted to R134A. If you can't find a label look at the ports on the compressor, if it was converted they will be quick disconnect fittings.

carefull, I saw several cars those have not convert or anything really done to the AC but it have the R134 fitting fit to the older fitting. At first I thought that's all I need but luckily before I pump R134 into my car, I did a search and found that
1- R134 and the older type mixed can turn into a jelly solution. 2- if only pumpin R134 into the older system without converting it = no cold air. Not sure it's they are true but that's what I have read.

Just a data point on converting: on a '90 acura I tried an R134 conversion last summer. I evacuated the old freon and used one of the R134 kits (included oil in the mix) from Advanced Auto. No new parts outside of the connection adapters. It worked just fine (most common problem is putting too much 134 in and causing the compressor to rapidly cycle - you need one of the pressure gauge units to really set the levels correctly). No jelly or bad things happening in the first 6 months.
