Re: Options to R12? (archive)

R134 is NOT a substitute for R12 in the fact that you have to change dryers, oil and perhaps O rings for a good job. Freeze 12 for example is a substitute but only should be used in a leaking system that you plan to NEVER get fixed when it goes because most shops will sniff it and not want to touch it.

I picked up a 12 can case for $360 this spring and by adding about two cans, one in the spring and one the first of August I can stay cool without having a contaminate gas mixture. R134 is the way to go if cash is not an issue. My loss rate has been consistent for 3 years so it cost me about $60 per year and I add it myself with the $5 hose and valve installation kit I have had for 25 years. I have 2 other non-leaking R-12 systems as well so if they do need topping off I am ready. One day I plan to be rich and get cars and trucks that shipped with R134 :) I do miss the days when Wal-mart had it for $.88 a can :(

I'm reading that R12 is quite expensive. R134 is a substitute. What are the ramifications? How much cheaper is it? I'm no longer getting any cooling out of my AC. Have never had a problem with AC (except engine tends to run hotter when it's running and car is idling, which I guess is another subject). Mechanic suspects its simply out of refrigerant. It's an '89 735i.

Thanks,

Rick
