Does adding too much antifreeze affect the car?

[Gama]

Adding too much antifreeze does not affect the car. If too much antifreeze is added, the excess can be drawn out from the expansion tank. Additionally, overfilling antifreeze does not impact the engine because the expansion tank is equipped with a drain pipe. When excessive antifreeze causes too much pressure, this drain pipe acts as a pressure relief, and the excess antifreeze will also be expelled through it. Automotive antifreeze is primarily used in the cooling systems of liquid-cooled engines, offering excellent performance in preventing freezing in winter, boiling in summer, scale buildup, and corrosion. Do not mix different types of antifreeze, and make sure to choose the appropriate antifreeze based on the region and vehicle model.
