It will not work. there is complete info in the FAQ; there are complete directions there. The short story, which I did a few weeks ago to my now expired 90 (see "Sadness" a few weeks ago), is to get the Volvo kit for around $80 or so, replace the accumulator (kit), change the orifice valve (kit, but maybe get the variable orifice valve separately), drain the compressor because the two different refrigerants use two different and incompatible oils and use the new ester oil (kit), vacuum the system thoroughly, and then charge it. Mine worked very well for the few days I had it, and many others report good results also.
