Don’t use tap water/ normal antifreeze in the cooling system. Use a product called Evans waterless coolant….

Very fine, lite pressure vapor blast or maybe even a small wire wheel. Blow out with air, repair with this F7D539B0-052F-4E5F-926F-201AD93D1112

I’ve used small Dremel sanding bits to clean out the pits, build up the area with JB weld and used the same sanding bits to shape the filler into a useable piece. If you can coat the whole passage it’ll stop further erosion.

It's not corrosion but result of cavitation.

No...not from cavitation.  Like the other post says, use Evans Waterless Coolant.

Galvanic corrosion (also called ' dissimilar metal corrosion' or wrongly 'electrolysis') refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte. It occurs when two (or more) dissimilar metals are brought into electrical contact under water..
