Listers,
Further to the question of using "soft" water in a coolant system, here is a
passage from the Filter Manufacturers Council Technical Service Bulletin
88-1R
MAKE-UP WATER
Proper coolant system maintenance requires a quality make-up water. All
make-up water is corrosive but water with high mineral content cannot be
made fit for use. As soft of tap water as possible should be used. Tap water
that has been softened by some type of salt or chloride process should not
be used. Most engine manufacturers have set up specifications for water used
in their engines.
