Notice in my first post I wrote that Bar's Leaks cuts electrolysis? I've got a copper heater core, brass barbs which is copper and nickle, and I guess th water block
has nickel barbs. So I only have 2 metals on the PC cooling system.
The engine on my truck I think is aluminum. The radiator/heater core is aluminum. Some car manufactures put this stuff in at the factory.
The coolant in my mom's Toyota Camry has a brownish color like Bar's Leaks. They've been selling this stuff since the 1904s it's safe to use in aluminum and copper based cooling systems.
