13.3. Cooling liquids
In system of cooling of cars Chevrolet Lanos it is recommended to fill in низкозамерзающую a liquid – antifreeze – a water solution этиленгликоля with addition of additives and neutral dye.
In the concentrated kind этиленгликоль its temperature of boiling +170 °С possesses high corrosion activity. Because of that that the crystallisation temperature этиленгликоля in the concentrated kind makes–20 °С, for fall of temperature of crystallisation it is diluted with the distilled water (tab. 13.1).
For neutralisation of corrosion activity in этиленгликоль add special additives. For difference from other operational liquid and simplification of definition of level in a broad tank of system of cooling of the engine in antifreeze add dye.
