EasyWhy is water used as a coolant in automobile radiators?
(N/A) Water is used as a coolant in automobile radiators primarily due to its exceptionally high specific heat capacity $(c = 4186 \ J/kg \cdot K)$.
Because of this high value,water can absorb a large amount of heat energy with a relatively small rise in its temperature.
Additionally,water is easily available,inexpensive,and has a high thermal conductivity,which allows it to efficiently transfer heat away from the engine block to the radiator fins where it is dissipated into the atmosphere.
