Please can someone tell me whereabouts the a/c 'expansion valve' is located and how best to access it? Thanks
Here's what it takes to access one for a 3.2 Coupe. Show us yours when you get there. . Image Unavailable, Please Login
Like Jerry says, see item #11 http://www.ricambiamerica.com/parts_catalogs.php?V=diag&I=1992 Image Unavailable, Please Login
Hi, thanks for that - is the only way to access the expansion valve on a Mondial T by removing the dash assembly entirely? If so, I may try to 'flush' the system first - has anyone had any luck doing that job?
A/C techs tell me that if you had compressor issues (internally) then there are contaminants in the system, which clog the expansion valve. A system flush might not dislodge all of it and then, in turn, damage can be inflicted on the new/repaired compressor. With that in mind, if the compressor is not the problem then I would certainly try the system flush first. BTW, when I was replacing my expansion valve this "new" one was sent to me. Of course, I rejected it as I'm sure that it's a used part instead. Looks like corrosion to me... Image Unavailable, Please Login
I did the flush. Seems to have worked reasonably well. But I really won't know until the Florida summer arrives. If the results are marginal, I would try a second flush before yanking everything apart. Prior owner changed out the refrigerant to 134, not sure if that makes a difference when flushing.

Hi, I am converted to 134 - how did you approach the flush? what 'flush' did you use please? My a/c is intermittent (compressor was replaced with new recently and new receiver dryer just fitted)
There is a post on here somewhere on how to do it. I let my tech do it, but as I remember, you run some ac flush through the system (once or twice) to flush it out, clean out the old refrigerant and then refill (make sure you have the proper amount of oil also). Or you can use mineral spirits with compressed air, then thoroughly clean with brake cleaner and vacuum the entire system. Then refill as above. Best to have a shop do it, since they can recapture the old refrigerant. Regards, Jerry
