Pure water has 1.4 times the heat-carrying ability of pure ethylene glycol, so water would be the best coolant to use if the only consideration in selection of a coolant was its ability to carry off heat. What are its other limitations?
What will be an ideal response?
It forms rust on iron engine parts. Cylinder walls vibrate during combustion, breaking off the rust. The coolant carries the rust to other cooling system areas. Hard water forms mineral deposits. The resulting corrosion interferes with heat transfer even before the results of it plug the radiator and fill the waterjackets with sediment.
