Castrol Anti-Freeze, Anti-Boil 1lt

DESCRIPTION

Glycol coolant for recirculating liquid cooled inboards and sterndrives. Reduces cavitation in areas such as the water pump and surface cavitations in hot spots of the cylinder head. Helps control pitting and cavitation erosion increasing component life. Raises the boiling point and lowers the freezing point of the engine coolant. Incorporates additives to guard against corrosion of cast iron, steel, copper and aluminum alloys used for engine components, heat exchangers and hot water systems. Mixing ratio of 30 - 50% by volume.
