Can Antifreeze Be Added?

[VictoriaFitz]

Antifreeze can be added, but it is not recommended to add it directly. Before adding antifreeze to your car, it is necessary to thoroughly clean the engine cooling system, especially during seasonal transitions when the antifreeze should be inspected. If the antifreeze level is insufficient, it should be replenished promptly. Cleaning before adding antifreeze is primarily to prevent chemical reactions between scale deposits in the engine and the antifreeze, as the detachment of scale can affect the normal performance of the antifreeze. Antifreeze is designed to prevent the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or the engine cylinder block to freeze. Its full name is antifreeze coolant.
