You have aluminum heads on a iron block, flowing liquid through a copper/brass radiator with a cooling system with metal parts is gonna need special attention to prevent damage. Fully flushed block, clean out radiator, ionized and mineral free water, correct anti freeze mixture and proper grounds will go a long way to keeping your engine running good and problems down.




As I am about to run Eddy's....on an Iron block...I was told to run a Zinc Anode on my cooling system as to have the dielectrolysis attack the zinc and not the block......Now the question remains....where do I put this anode? In a water jacket or in the radiator somewhere?
