The Difference Between Coolant and Cooling Water

[MaliaLynn]

Coolant and cooling water each have their own functions: 1. The role of automotive coolant: Coolant is an indispensable part of a car engine. It circulates within the engine cooling system, carrying away excess heat generated during engine operation, allowing the engine to operate at normal working temperatures. When coolant is insufficient, it will cause the engine water temperature to rise too high, leading to damage to engine components. Once a car owner discovers insufficient coolant, it should be promptly replenished. 2. The role of cooling water: In the engine's cooling system, the thermostat controls the water within the engine body, directing it to the radiator, where the water in the radiator dissipates heat through the airflow from the cooling fan. There is also a crucial aspect to this, which is the material and function of the cooling water. Depending on the design of different manufacturers, engine temperatures are not always below 100°C. Ordinary water boils at 100°C, and once water boils and turns into steam, it can no longer absorb heat. The inability to absorb heat will cause engine damage, so cooling water cannot be replaced or supplemented with ordinary water. Using coolant is the standard practice.
