You'll get that response with almost any bolt since it's two dissimilar metals in contact with each other. The real solution is to isolate the cooling system from the electrical system to retard or eliminate the catalyst for the reaction to occur, since there's always going to be a grounding effect from the charging system on the block it's just about impossible to do. The next best thing is a sacrificial anode. It's just a stud that will get eaten instead of the aluminum saving the pieces of your engine and radiator.
