What are the consequences of driving without coolant?

[McElliott]

Driving without coolant can leave the car's engine and radiator unprotected. A lack of coolant affects the heat dissipation efficiency of the radiator, preventing it from achieving the necessary cooling effect. Without proper coolant circulation, the engine may overheat, and in severe cases, this can lead to engine damage. In cold climates, it may also cause the engine or radiator to freeze, resulting in engine failure and rendering the vehicle unusable. Methods to check if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it likely indicates low coolant levels, though it could also be due to excessively high cylinder temperatures. Inspect the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add coolant promptly. Check the water level markings on the coolant overflow tank. The normal coolant level should be between the maximum and minimum marks. If the coolant is below the minimum mark, it indicates a deficiency.
