Can water be added if the coolant is low?

[LaEthan]

It is not advisable to add water when the car engine coolant is insufficient. Here are the reasons why water should not be added when the car engine coolant is insufficient: 1. Water has a low boiling point and is prone to boiling over, resulting in poor cooling performance. 2. Water has a high freezing point and is prone to freezing, which can affect the car's operation if the engine or radiator freezes. 3. Water contains impurities and ions, which can easily form scale and cause blockages. Here is some relevant information about coolant: 1. Coolant has functions such as antifreeze, cooling, anti-corrosion, and anti-scaling. 2. Coolant contains water, but this water is soft water, which is distilled water that has undergone deionization and softening treatment.
