A hose failure of that type is indicative of an overpressure condition.
Make sure the coolant system is working properly and inspect for other
hoses that are stretched. Replace the pressure relief cap. Keep on eye
out for internal head gasket problems.

Well,
This morning I took a look at the Van's engine bay and looked at all the
hoses. I then noticed dried coolant that leaked out from the day before
right below one of the large hoses to left of the engine.
I started feeling around and sure enough I noticed this large hose was
very
close to transmission and there was a small section that felt like it
was
covered with oils and grime, and under that layer it felt really, really
thin, as if it were worn or stretched out.
I begin to feel that area and sure enough I found a crack that ran
about 1
inch long and I could literally press my finger right into the hose!
I went to the Vanagain.com website and looked up the hose as well as the
entire hose map and started to look for any other offending hoses, I
could
only find the one but decided to bring it to my VW guys for them to
review.
They too agreed on the hose and would give it a thorough review.
Thanks to every one for their feedback.
