I think it's called a coolant bypass pipe, (It's job is to serve warm
coolant to the head when the block is cold & to allow for coolant
circulation when the thermo is closed, thus letting the waterpump move
coolant at all times), but my PC here at work is in a box and the Mac
has no VirtPC to run the ETKA CD from at the moment.

It's true, what with our multi-metaled engines that electrolysis is a
problem, over the life of the car as we know it. (Going on 20+ years and
counting) The coolant pipe seems to take the hardest hit (best that IT
is what goes I guess).

Makes me wonder about this product I saw that hangs down from your
radiator cap and dangles a small metal blocks in the coolant. IT
dissolves in the the coolant, giving up itself instead of your engine
components- Anybody tried this thing before?

Chemist on the list, comments?

Thx for you time.
