MEngr is correct
if you follow the mfg's recommended service and use their recommended fluids you should have a minimal problem with corrosion. I'm not saying it will totally dissipate but it should be reduced drastically.
One of the biggest problems with these kind of issues is the miss-application of maintenance proceedures and materials. If you mix brands of coolant or mix it incorrectly you will in the longrun have these kind of issues. If you mix types of coolant the issues will get alot worse because of incompatibility between coolant types.
If it calls for ELC then use ELC
If it calls for Dexcool? then use Dexcool
If it calls for just a general glycol based coolant (the green or yellow kind) then use that.
But as i have seen i do not think they have created a glycol based coolant that didnt eventually corrode/deteriorate aluminum at some point.
