William: I have had a similar experience. I had the green anti-freeze in and then I thought that I'd better use the "good" VW (expensive) orange stuff - when I did I got leaks from nearly every hose clamp and also ever-so- slight weeping from the head gaskets. My (trusted) mechanic says that it has something to do with molecule size and he suggested that I go back to the green stuff. Go figure.
