Sacrificial anode?

[36tudordeluxe]

Got aluminum heads on '36 LB engine what can I use to slow down or stop electrolysis? Going to use graphite head gaskets now.

I use radiator caps that have the sacrificial anode attached. Now if I can recall the name. Maybe Rad Cap?

i get anodes at a marine store and screw them into the water pump or xtra hole at water neck.they have all sizes.

Most modern antifreezes mixed with distilled water are compatible with and protect aluminum components.

The water wetter I've been using says not to use distilled water. I put water pump lubricant in my other flathead and they claimed it would prevent electrolysis, haven't pulled the heads on it.
I see Summit has the Rad Cap, will order one.

I agree distilled water is not the best choice. But, a good, modern antifreeze is essential.

Here's another alternative: http://www.no-rosion.com/norosioncoolant.htm

Here is what I and a few others use. A friend who has aluminum heads and radiator uses them up pretty quickly, maybe once a year. The anode is replaceable.

I had a bung put in my radiator and installed an anode to protect my Ardun heads.
