What are the consequences of a car lacking coolant?

[DiPhoebe]

Lack of coolant in a car can affect the heat dissipation effect of the radiator, failing to achieve the necessary cooling function. This disrupts the normal circulation of coolant, leading to high temperatures and, in severe cases, causing engine burn damage. In cold climates, it can also result in the engine or radiator freezing, leading to engine failure and rendering the vehicle unusable. Methods to determine if coolant is lacking: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to a lack of coolant, although it could also be caused by excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add coolant. Inspect the water level scale markings on the coolant tank. Normally, coolant should be between the maximum and minimum water levels. Whether coolant is lacking depends on the scale; if the coolant is below the minimum water level, it indicates a shortage of coolant.
