GENERAL INFORMATION

The cooling system of the engine has to be filled with mix of water, antifreeze and G12 rust-preventing agent. Additives in cooling liquid exclude defrosting of the block of cylinders of the engine and formation of corrosion and a limy deposit, and also increase temperature of boiling of cooling liquid. Because the cooling system of tight type, when heating cooling liquid in the cooling system is available the excessive pressure which also promotes temperature increase of boiling of cooling liquid. Restriction of pressure in the cooling system at the level of 1,2–1,5 bars is carried out by the valve in a cover of a broad tank.

At a liquid dolivka in the cooling system even in warm season use only mix of antifreeze, G 12 rust-preventing agent and clear water with the low content of lime.
