As long as there is dissimilar materials in a cooling system you WILL get electrolysis IF the proper amount of antifreeze is not added. Water transfers electricity and then add the dissimilar metals and electrolysis happens if not maintaining the proper mixture of coolant to water. Electrolysis in the Cooling System
I agree with the whole Dissimilar Metals as the cause of this and not the fact that the Aluminum Rad is in contact with the Steel Rad Support. There is no metal to metal contact there and no coolant (fortunately) on the outside of most peoples rads.
While I also think of Electrolysis in this manner, the correct term for what we are talking here is "Galvanic Corrosion" at least based on this article.
Todays word is.... "Galvanic"...
