Water is used in car radiators because :
- it is a good conductor of heat.
- it conducts heat faster as compared to the other substances and cools the engine quickly.
- its specific heat capacity is very low.
- its specific heat capacity is very high so it can cool the engine without a greater increase in its own temperature.

Answer
its specific heat capacity is very high so it can cool the engine without a greater increase in its own temperature.
Reason — Water in car radiators can absorb more heat without much rise in temperature due to it's high specific heat capacity. Hence, it acts as an effective coolant.
