Expert Answer:

Water has a very high specific heat capacity, that is, to raise the temperature of unit mass of water by 1 °C, a large amount of heat is required.
Car radiators get heated up by large temperatures. Water can easily take up this heat without getting heated up itself.
 
This cools the radiators quickly. Hence, water is used in car radiators as a coolant.
