Does Overfilling Antifreeze Affect the Car?

[DeJulian]

Overfilling antifreeze can cause the vehicle to experience thermal expansion while driving, leading to overflow from the pressure relief valve and leaving stains. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking. The functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. The composition of antifreeze: The main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances. The types of antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering them ineffective.
