Sacrificial Anode

[RETed]

It's an ongoing debate...

You can minimize this by 1) keeping the "electrolyte" serviced. and 2) keep electrical potential to a minimum.
#1 has already been talked about...
#2 you can check resistance at potential areas, and the addition of grounds (wires) can help here.

I don't believe this is a big problem unless you don't change and flush your coolant at proper interviews - this should be covered with proper maintenance.
Blowby from combustion drops the pH levels in your coolant...
Acidic pH increases the chances of galvanic corrosion.
If your radiator starts to develop pin-hole leaks all of a sudden - this is usually the most obvious problem - then these sacrificial anodes might be a waste of money.

KISS...
