Antifreeze - means of protection from freezing

Cooling liquid

Broad tank of system of cooling


The system of cooling is all-the-year-round filled with a mix of water, antifreeze and anticorrosive means. It interferes with a rust and corrosion, adjournment of salts and, besides, increases temperature of boiling of cooling liquid. In cooling system because of liquid expansion when heating superfluous pressure is created that also conducts to temperature increase of boiling of cooling liquid. Pressure is limited located in a cover of a broad tank to the valve which opens at pressure 1.4 – 1.6 atm. Faultless functioning of system of cooling of the engine needs the increased temperature of boiling of cooling liquid. At low temperature of boiling the steam stopper therefore circulation of liquid decreases can be formed and cooling of the engine worsens. Therefore the cooling system all-the-year-round surely should be filled with a mix of water and the listed additives to it.
