I know that this a topic which MANY of us avoid, partially because of ignorance and partially because of expense (especially with R-12 systems). However, if some of ue can do MINOR fixes on our own cars to get the A/C's up and working, it would be great! AND we can show off our cars more! Obivously, there are those of us who are mechanically Professional and those of us who are not, some in between. We all have our forte's and our weaknesses. I love to work on the electrical, but I can replace seals (and failed parts) and follow instructions very well. And sometimes EVEN repair parts TOO. I am very weak in the A/C area and would like to know a couple of things about it from those in the know. I can be a bit of a perfectionist, and like to do something ONCE the RIGHT way, because I do NOT want to have to go back and re-do it to repair failed parts nor stupid mistakes. NOW, I want to replace ALL of the seals in the A/C systems of our 93 and 75 Imperials and our 92 Grand Voyager (could be a bit of a pain as it has DUAL A/C) with the newer GREEN o-rings. Are they longer lasting and compatible with ALL refridgerants? I want to have the remaining R-12 suctioned out and "washed out". Does any one know if Harbour Freight sells an inexpensive Vacuum pump that will do the job? ( AND what should I look for in one?) And after having opened the system to replace the O-RING seals ( with oiled green ones), are there ANY components which SHOULD BE or MUST BE replaced for longivity without lose of refridgerant and failed OLDER parts? I am on this at this time as is has been over 100 for sometime now here in Tucson and I am experiencing over heat in the 93 caused by a less than proper charge in the A/C system. Also I want to get the A/C on the 75 working, it came with a spare plenum and other A/c parts. I am looking to charge the systems with FREEZE 12, but I am not sure how much oil to put into each system. I was very glad to here that we have members using FREEZE 12 and have not have any problems with it. ALSO, how much ORIGINAL R-12 went into each system? I do hope that the answers to this will help many others here in the US and in other countries.
