What is the reason for the engine coolant running out?

[LeRuth]

Engine coolant running out is caused by the gradual loss of coolant during the water circulation process. Detailed introduction to engine coolant: Since water-cooled engines rely on coolant for cooling, the cooling effect will be significantly reduced if there is no coolant. Therefore, car owners should regularly check the coolant level to ensure it is sufficient and prevent engine overheating. Coolant leakage is usually caused by cracks in components such as hoses or radiators in the cooling system, which is considered external leakage. There is also internal leakage, such as cylinder gasket seepage. If a leak occurs, the cause should be promptly identified, and the cracked part should be located. Precautions for engine coolant: Draining the coolant: First, open the reservoir cap (ensure the radiator cap is tightly sealed), then loosen the drain switches on the engine block and radiator. This should be done while the engine is running at low speed and warmed up. After the coolant is completely drained, tighten the drain switches on the engine block and radiator.
