[DML] Re: Stainless in coolant system

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

One of the biggest things you can do to prevent galvanic corrosion is
to change the coolant regularly. Once it gets acidic it is a lot more
conductive and will enhance the corrosion process. I also believe that
charging the battery in the car impresses an A/C current in the
cooling system. Over time it can also lead to galvanic corrosion. Same
goes for any block heaters or anything that connects a car to the
household electric. That's one of the reasons why I do not like I see
those floating trickle chargers always hooked up to the battery [in
the car]. I see no harm in changing the header bottle to S/S.
