Thanks for all the replies!  I'm a wiz with bicycle mechanics but
working on a motor vehicle is whole new world...  I've only had my
Vanagon for 6 weeks, so I am Super Neophyte.

I've look around at the archives.  I think I'm going to remove the hoses
at the T joints.  Most complicated short term, least complicated long
term.  I'm not getting rid of the heater; I'll store it and re-install
it when I move to Northern Alberta.

My next question is in regards to a replacement for the T joints.  What
materials should I avoid, other than ones that will melt?  Is there any
metal that will cause corrosive problems when in contact with coolant?

I'm also wondering what I can use to pinch the hoses?

Cheers,

Kirk
