      What coolant do I need for my BluePrint Engine?

      We recommend you use a quality name brand extended life coolant, a 50/50 mix of antifreeze and distilled water to fill the radiator and engine.

      Check the label of the brand you choose to ensure the compatibility of the coolant with your engine metals (cast iron, or cast iron and aluminum) and radiator
      material. BluePrint also offers our own brand of coolant concentrate:
