Is it a big deal if the coolant is only half full?

[AaliyahLee]

If the antifreeze is only half full, it means it needs to be topped up. Whether you can continue driving depends on whether the car's water temperature is too high. If the water temperature reaches above the red line, it's better not to continue driving. If you can't add antifreeze immediately, consider stopping the car and letting the engine idle to lower the water temperature. Below is an introduction to car antifreeze: Introduction to Car Antifreeze: Car antifreeze, the full name should be car antifreeze coolant, meaning coolant with antifreeze function. To ensure the car can still be used in low winter temperatures, engine coolant is mixed with substances that can lower the freezing point of water as antifreeze, keeping the cooling system from freezing in cold weather. The role of antifreeze: Antifreeze can prevent the coolant from freezing and expanding when the car is parked in cold seasons, which could crack the radiator and damage the engine cylinder block.
