Can a car run without coolant?

[SanAnthony]

It is not advisable to drive a car without coolant. Prolonged driving without coolant will cause the engine temperature to rise continuously, leading to overheating. In severe cases, it can damage the engine. You should pull over, turn off the engine to lower the temperature, and only resume driving after the engine has cooled down. However, driving time should not be too long, and coolant should be replenished promptly. Coolant, also known as antifreeze coolant, is designed to prevent freezing in cold weather, protecting the radiator and engine cylinder block from cracking due to freezing. Antifreeze is not just for winter use; it should be used year-round.
