Can I Add Water When Coolant Is Insufficient?

[VanAshley]

In emergency situations when coolant is insufficient, you can add water, preferably purified water, but this is only to prevent the engine temperature from rising too high due to insufficient coolant. After adding water, the freezing point will decrease, so it is important to promptly check the coolant's freezing point, which varies depending on the ambient temperature. Coolant is an essential part of a car's engine, circulating through the engine cooling system to remove excess heat generated during engine operation, ensuring the engine runs at the proper operating temperature. When coolant is insufficient, the engine's water temperature may rise too high, potentially causing damage to engine components. Therefore, if a car owner notices insufficient coolant, it should be replenished promptly.
