Exploring options to prevent corrosion from electrolysis in cooling system. Along with correct anti-freeze/distilled water mix and possibly an additive to minimize corrosion...... I am looking at sacrificial anodes. I understand there are both zinc and magnesium anodes available for marine engines, so am looking at these......

Son's 350 engine will have iron block, aluminum heads and intake manifold. My 292 inline 6 is all iron...... Will not have any aluminum parts in contact with engine coolant but I am looking into this anyway. Both will run copper/brass radiators (no aluminum radiators) but whatever is shared in this thread should certainly be helpful to those who do.

What are y'alls experience and thoughts on this?

Thanks,

Harry
