3.1. Dolivka of cooling liquid


The system of cooling of the engine should be filled with a mix of water, antifreeze and anticorrosive means of G12. 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 – tight type, when heating cooling liquid in system of cooling is available superfluous pressure which also promotes temperature increase of boiling of cooling liquid. Pressure restriction in cooling system at level 1,2–1,5 bar is carried out by the valve in a cover of a broad tank.

At a liquid dolivka in cooling system even in a warm season use only a mix of antifreeze, anticorrosive means of G 12 and at its finest limes with the low contents.
