[s-cars] The great coolant debate...

[R. Mair]

Green coolant is typically only corrosive if it hasn't been properly flushed
at regular intervals. After years/miles of heat, cold, combustion gasses and
the like, the anti-corrosive properties will fail and yes, green stuff will
become corrosive. I've seen pitting on the cylinder heads of of late model
VW's, under the coolant outlets, due to old G12 (pink). Dexcools claims to
fame is that it is relatively non-toxic, especially to animals. They have
given up allot of heat transfer capabilities so that in case your pooch
starts lapping up the leak on your driveway, he'll only get a good headache
from it. Sorry, but that isn't good enough reason for me to comprimise my
expensive turbo engine.There are plenty of good green coolants out there,
just stick with brand names and regular flushes.
