Car Radiators Hydrometers Are Used To Determine The Density Of Water In A Car Radiators.?

Hydrometers are used to determine the density of water in a car radiators.? - car radiators

Since the density varies with the amount of antifreeze added that it is possible to determine the proportion of antifreeze in the radiator and the temperature at which it was frozen. The knowledge of the specific gravity of 0,958 Ethylene glycol is a radiator with fluid with a density of 0976 or 0989 will be better prepared for the cold? Please explain.
