Can I add water if the coolant is insufficient?

[LaParker]

It is not advisable to add water when the coolant is insufficient because water has a low boiling point, which makes it prone to boiling over, and its cooling effect is poor. Additionally, water has a high freezing point, making it susceptible to freezing, which can affect the car's operation if the engine or radiator freezes. Moreover, water contains impurities and ions, which can lead to the formation of scale and cause blockages. Coolant serves multiple purposes, including antifreeze, cooling, anticorrosion, and anti-scaling. Although coolant also contains water, it is soft water, specifically distilled water, which has undergone deionization and softening treatment. If the engine coolant is insufficient, you can add soft water, but be cautious about the amount added. Adding too much can alter the coolant's boiling and freezing points. Do not add hard water like tap water, as it can have adverse effects.
