Will adding too much car coolant affect the vehicle?

[StAna]

Adding too much car coolant will not affect the vehicle, as it has an overflow valve that allows excess coolant to drain out. Coolant, also known as antifreeze coolant, is designed to prevent freezing during cold seasons, protecting the radiator from cracking and the engine cylinder block from freezing damage. Car coolant is not just for winter use; it should be used year-round. In standard vehicle maintenance, engine coolant should be replaced every year. Coolant consists of water, antifreeze, and additives, and can be categorized into types such as alcohol-based, glycerol-based, and ethylene glycol-based, depending on the antifreeze component.
