I smelled that for a couple of years before I found this vanagon list!

It was almost "misting" out of mine, so no "leak" was visible unless you
got back there with the housing removed and ran the engine.

It's an easy fix, except you have to bleed the coolant system afterwards...
That's always a hassle...

Pull up the carpet padding and you'll find out just how much it's been
leaking...
Mine was all thick and gooey...

good luck!
