While we are on this thread, I noted copper pipe was suggested as a
replacement, would this not cause electrolysis problems, from my dim memory
of school chemistry, I thought aluminium and copper set up a wonderful
electrical cell?
Would one not end up with aluminium coated copper, and no cylinder block?
Anyone able to confirm copper coolant pipes are ok to use as a repalcement
for steel or plastic?
John.
(PS This IS how we spell Aluminium in this part of the world.)
