Can the car still run without coolant?

[ODeclan]

The car cannot continue to run without coolant. Here is an introduction to the cooling system: The function of coolant: The function of coolant is to dissipate heat for the engine. Without coolant, the car's engine and radiator lack protection, which affects the heat dissipation effect of the radiator. The engine temperature will continue to rise without effective cooling, and the antifreeze cannot circulate normally. If you continue to drive, it may cause severe engine damage in serious cases. In cold climates, it can also cause the engine or radiator to freeze, leading to engine failure and rendering the vehicle unusable. The optimal coolant level: The coolant reservoir usually has max and min level markings. If the coolant level is below the minimum mark, it indicates insufficient coolant, which needs to be replenished promptly. The optimal amount of coolant should be between the max and min levels.
