Allan,
It would be interesting to know (if possible) how the coolant works
its anti corrosion function,
I know VW was adamant about changing it yearly
which I know we never remembered to do that often.
But does it actually have a sacrificial anode type of additive
that is used up over the course of a year, if it does then the
more dissimilar the metals and the closer they are to each other
the more powerful the reaction.
Does anyone know an answer to this?
Electrolysis of the old waterboxer heads was one of the main problems that
caused
them to leak.
Keeping the metals similar has got to be the preferred method, no matter
whether its sea water or kool aid coolant.
We made up the one fitting that requires welding in our shop by Mig
welding and it probably took less time to make then a copper T with
the soldering.

Subject: Re: [subaruvanagon] Stainless radiator pipes???
Thanks a lot to every body who replied :-)
So SS sounds fine - YAY! I have acess to people who can tig and mig weld
stainless and aluminium, so that should pose no problems. Sounds like all
I
have to do is to stop it rubbing on stuff. Most (all?) the conections
btween
two pieces of pipe will be made with rubber, or welded, so the corrosion
shouldn't cause rupturing.
I was wondering about the electrolytic corrosion because my father used to
sell boats, many of which were aluminium - there was one where a guy used
a
brass block to mount his depth sounder transducer - it made a VERY thin
part
in the hull!!!
I'll try to use as much aluminium/stainless as posible.
Also I suppose an aluminium radiator would be best too, rather than a
copper/brass one:-)
(PS my conversion is actually going in a beetle based car :-)
THANKS!!!
Allan :-)
