Hi all,

As my Vanagon's coolant pipes need replacing this winter (I only drive it
for six months out of twelve) I'd like to ask a question or two about using
copper pipe to replace the long steel pipes that run under the floorpan:

How suitable is copper?  Is it subject to attack by phosphates or any of the
other nasty chemicals in coolant?  Will the products of any corrosion of the
copper (mainly copper salts) act as catalysts for any differential corrosion
between steel and aluminum?

Are there any "better" choices?  Is stainless steel an option, bearing in
mind that it is only "stainless" at normal ambient air temperature?  Is the
original steel material a good replavement, subject to being wrapped in
anti-corrosive Denso tape?

Sorry for so many questions!  I want to do this job once, and only once ....
for at least the next ten years!  (Born optimist!)

Best regards,

Tony

'84 Vanagon Reimo.
