Genuine Nissan radiator coolant (L248SP) has advanced formulation for aluminum and cast iron engine parts. This Nissan radiator contains no amines, no silicates, which may harm water pump seals, or borates that may cause aluminum corrosion and pitting which would cause your radiator to malfunction quicker.
The genuine Nissan radiator coolant is a 100% concentrated product which means it should be diluted to a 50/50 ratio. This mixture ratio ensures maximum cooling system efficiency and excellent corrosion protection for your radiator.
The pre-diluted one gallon container is already a 50% antifreeze and 50% distilled water mix. Do not add additional water when using pre-diluted Blue LLC
