patcal Posted November 27, 2003 Share Posted November 27, 2003 Hi all, While I try to find a used TCU I thought I would look at my AC system. It is low on charge & the compressor kicks on & off. I am assuming because of the low charge. I am thinking that in the long run it will be cheaper to convert it to R-134 then to just have it leak checked & charged with R-12. I think I saw retrofit kits of the Subaru somewhere. Any idea if there is a specific one needs & how much do they cost? Also, is this something a home mechanic can do? Thanks.

p.monro Posted November 28, 2003 Share Posted November 28, 2003 Hi patcal I am working on my AC at this time having received an estimate for about US$500 to fix it when I expected about $US 250. The AC workshop claim they found leaks in the TX valve and the shaft seal. I have the TX valve out and it has a leak caused by corrosion under the "O" ring seal which I have cleaned and am getting ready to pressure test. I believe I can fix this US$80 item for nothing. I will also clean the evap whilst it is out. It is covered in rubbish. Then I will pressure test the system and evaluate the shaft seal leak. My hope is that I will live with a small shaft seal leak. I am also looking for R134A and the kit. I expect to find it at an auto store. My guess is that if you are low on gas then you will have a leak somewhere Have a look at Josh's link. It has good info on prices. I expect to pay about US$15 for the kit and Josh has the gas prices. Haynes manual also has a good section on AC Regards Peter Quote Link to comment Share on other sites More sharing options...
