What to Do If Too Much Antifreeze Is Added?

[NathanAnn]

If too much antifreeze is added, simply pour out a small portion. Adding too much antifreeze has no significant impact on the car, but the reservoir may overflow, corroding surrounding metal components. It is recommended to drain the excess antifreeze and store it separately for future use. Antifreeze is a coolant with anti-freezing properties, preventing the coolant from freezing in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head. Adding antifreeze to the radiator water turns it into a mixed solution, lowering the freezing point and making it less prone to freezing. Additionally, its boiling point is relatively higher, reducing water evaporation in summer and enhancing the engine cooling effect. Antifreeze also has anti-corrosion properties, preventing radiator corrosion and lubricating the water pump bearings.
