--------------6038DF5E2D78909A716E64F1 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit HEY! What are you talking about guys???! - YOU DONīT HAVE TO CHANGE ANY PART OF THE AC SYSTEM when you change form R12 to R134! - I had it changed last year! The problem is that your AC already stopped working, that means - thereīs a leak! - Iīm annoyed cause that happens very often on Saab AC systems (mine too) - and the AC will be empty regularly (every year) if you donīt find the leaking AC component! Sometimes itīs the evaporator, sometimes the hoses, not very often the compressor. All the oil has to be removed form the AC system and filled up with a new fluid that works with R134 (fluid ~100 U$) and then the system is pressured with R134 gas. (same price) Itīs wise to add a contrast component to the gas to find the leak! If you are lucky itīs obvious which component leaks - if not it takes some weeks to find it (the contrast fluid can be detected using UV-lamps). Then depresurize the AC (collect the expensive R134 gas), change the unit and fill it again. Greetings, RCS BGJ > I have a 9000 CD 2.3 T from 1991.
