I just figured any responsible auto manufacturer would put a high pressure switch on an AC system. Sure, in production runs as high as VW this would be expensive, but not nearly as much as litigation an recalls. When did VW start using them? My 77 scirocco had them, so does my 86. I never bothered checking my van, haven't got to that point in the buildup yet. >> Sadly, I don't have one to look at (Westy with AC wannabee). Help me out...Doesn't the bottom of the receiver-filter-dryer have a one-shot, blow off-valve for high pressure??? I thought all them did. It is a little 10mm bolt, with a plug of alloy in the center that melts at a very certain temperature, acheivable only under sickening pressure. This plug keeps your AC system from completely fritzing when you don't change the filter/dryer or run into any other high pressure situation (360-degree performance review, home loan appraisal, birth of septuplets, etc.) Don't Vanagons have these??? gmbulley cary, nc |
