What are the consequences of a frozen car radiator?

[McNicole]

If a car radiator freezes, it will prevent the establishment of a cooling water circulation system. Starting the engine under such conditions can cause the engine to malfunction due to overheating. Introduction to the car radiator: The radiator is a key component of the car's cooling system, also known as the overflow tank. Its function is to maintain the engine temperature. How the radiator works: Coolant circulates through the engine's water passages, absorbing heat from the cylinder block. It then dissipates this heat through large cooling fins, maintaining the engine's optimal operating temperature. The radiator is composed of hollow copper tubes, through which the high-temperature coolant flows, cools down, and then recirculates back to the engine cylinder walls. Main functions of the radiator: When the engine's water temperature is high, the water pump circulates the water repeatedly to lower the engine's temperature, thereby protecting the engine. In winter, if the water temperature is too low, the circulation stops to prevent the engine from becoming too cold.
