[DML] Re: Cooling Fans Automatically Come On



The Ethylene-Glycol based coolant becomes acidic with age. As it
becomes more and more acidic it wil start to attack the metal
components of the cooling system usually starting with the lesser
noble elements like aluminum. It also becomes more conductive so it
acts more and more like an electrolite conducting current, again
attacking the less noble elements starting with aluminum. Go back to
your High School chemistry, the Electromotive Series. Corrosion is
basically an electric action except for fatigue corrosion. Anyway I
don't believe it is the coolant's chemistry that destroys the
Otterstadt, but it will attack the metals of the system. I lean
towards Buce Benson's suggestion that once you overheat the system you
probably damage the Otterstadt. But what came first? The bad
otterstadt or the overheated system? If either can cause the other one
then it is difficult to figure out which one died first. Bottom line,
change the coolant (or at least test it) every 2 years and change the
Otterstadt if you overheat the system.
