The heat capacity is basically how much heat energy the coolant can carry out of the engine and to the radiator.

As far as carrying heat goes, water does a really good job. It’s actually one of the most effective coolants that could possibly be used.

The specific heat capacity of ethylene glycol is only about 65% of water at the temperatures seen in a cooling system.
