5.3. Antifreeze for a radiator
The cooling system a round code is filled with the mix consisting of water, antifreeze and anticorrosive means. This mix prevents emergence of the damages connected with freezing and corrosion influence, formation of limy deposits and, besides, slightly increases temperature of boiling of cooling liquid. Thanks to a carving cover on a compensation tank, at the heated-up engine in the cooling contour the excessive pressure about 1,4 bars which promotes temperature increase of boiling of cooling liquid too is created. The increased temperature of boiling of cooling liquid is required for normal functioning of the cooling system of the engine. At too low temperature of boiling of liquid it can give to thermal a subtime because of what circulation of cooling liquid is broken and cooling of the engine decreases. Therefore the cooling system within a year has to be surely filled with mix of the cooling concentrates.Prevention
As after a while the anticorrosive component in cooling liquid loses the effective influence, cooling liquid should be replaced every 3 year.
