Antifreeze Siberia blue is intended for cooling internal combustion engines, can be used as a working fluid in heat exchange units operating at low and moderate temperatures. Coolant antifreeze reliably protects aluminum and other metal parts of the cooling system from corrosion, extending their service life and preventing engine overheating. It is necessary to apply antifreeze in accordance with the operating instructions for the car and heat exchange units. It is used in the cooling system at temperatures from -40 °C to +120 °C. At temperatures above +120 °C, it boils, and at temperatures below -40 °C, it begins to freeze.
