> Aside from the corrugated bit I like your theory. I just checked mine again and sure 'nuff, like yours, it's NOT corrugated. There's a pattern of rust on it that gives it the APPEARANCE of an uneven surface. I clearly didn't look very closely before I tossed it into my toolbox, cursing VW engineers righteously as a lay on a piece of cardboard under my van at a gas station off US-101 on Malibu Canyon Road.... Looking at that, I feel I must amend my theory slightly. I suspect that it's not just cooling system pressure, but also that the clamp is squeezing the soft tube, pushing the steel insert out, like toothpaste out of a tube. That fits better with the nature of the GoWesty fix, I think. -- John Bange '90 Vanagon - "Lastwagen" '90 Vanagon GL - "Wiesel" |
