[C320-list] Water heater replacement now coolant.....

[Hans Dose]

The important thing to remember is if you are changing FROM the ethylene
glycol (green) antifreeze TO the Dexcool-type Extended Life Antifreeze
(Orange colored ex. Prestone 5yr/150000mi), the complete flushing of the
system multiple times to rid the system of the green type is crucial so
that it doesn't coagulate. They don't mix!

I left the ethylene glycol (green) antifreeze in my system instead of
switching.
