Thanks for helpful replies to my question on the coolant pipe.  Much to my
surprise it was available at the VW dealer in Juneau.  I would like to
replace it myself, but am a bit intimidated about bleeding the cooling
system.  The part number on the pipe is  025 121 281 G.  Since the pipe sits
down close to the exhaust system, but is low enough to be exposed to road
salts, etc, is it worth trying to treat it with something to prolong its
life?  Does anyone have any experience or a previous post on replacing the
pipe?  For example the cap screws on my 86 Vanagon engine that attach the
flange to the water pump look like they are allen type (they are quite
rusted).  Why don't they use regular hex head screws, and any ideas what the
torque specification would be?

Thanks
