the plastic pipes..
particularily at the front ends of them, near the radiator, are
notorious for having the a metal insert slip out of place, out of the
end of the plastic pipe....causing a leak ..
and sometimes, a sudden large leak.
I've had it happen out on the road in a seemed-just-fine personal
Vanagon, and I've seen a wonderful Vanagon in a junkyard with fried
engine for this Exact cause.
you might keep an eye on this spot, you might pull the hose off and
're-do' in there, etc.
GW sells a kit I gather, as well.
fwiw, if I was going to attempt to re-glue the metal insert back into
the plastic pipe, I'd use Marine Tex ...one of the best two-part epoxies
you'll ever find.
in any case..investigate that spot further I suggest !
