Is there any impact if the car's antifreeze exceeds the max level?

[DeLucia]

There is no impact if the car's antifreeze exceeds the max level. The excess antifreeze will expand due to heat during the car's operation and overflow from the pressure relief valve, causing no harm but leaving some stains. It is recommended to remove the excess with a syringe. Generally, the antifreeze reservoir has a max water level mark and a min water level mark. The antifreeze should be filled between the max and min levels. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze function. It can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking.
