When the engine blew on Billy Bones on that fateful journey from NC about a year and a half ago, it was that same little s-shaped hose that was the culprit.  It was about 20 degrees outside and 3:00AM.  I was driving along and my temp light blinked, then stopped.  I looked at my temp guage as it dropped!  I instantly pulled off the road, but it was too late.  Steam was rolling into the night air, and the days of my mechanical adventures just beginning.

Because of that experience, I changed every hose on my Vanagon when I installed the new engine.  Those hoses can and will fail catastrophically.  Unfortunately I had to learn this the hard way.
