What Kind of Water Should Be Added to the Radiator?

[MicahFitz]

The water added to a car's engine radiator is antifreeze coolant, also known as antifreeze or antifreeze coolant. Its primary function is to cool the engine during operation, ensuring the engine works at normal temperatures, preventing overheating in summer and freezing in winter. Important Notes: Do not add water to antifreeze: Adding water to antifreeze will raise its freezing point, reducing its cooling effectiveness. Moreover, tap water contains impurities such as scale, which can cause sediment buildup and impair the performance of the car's cooling system. When replacing antifreeze: The cooling system should be flushed internally to remove any existing scale, as antifreeze contains descaling agents. If scale is not properly cleaned, it can affect the performance of the new antifreeze when added.
