How Far Can You Drive with Insufficient Car Coolant?

[VonEmilio]

You should not drive with insufficient car coolant. The solutions are: 1. Pull over immediately and turn off the engine as soon as possible; 2. After the engine cools down, open the front hood to inspect; 3. Visit a 4S store promptly to have professionals add coolant. Coolant, also known as antifreeze coolant, is composed of water, antifreeze, and additives. Based on the antifreeze component, it can be classified into alcohol-based, glycerol-based, and ethylene glycol-based. The functions of coolant are: 1. Preventing the coolant from freezing and expanding during cold seasons, which could crack the radiator or damage the engine cylinder block; 2. Preventing corrosion of metal parts and aging of rubber components; 3. Reducing scale formation to avoid clogging circulation pipes and impairing the cooling system's heat dissipation function; 4. Preventing the engine from overheating, ensuring it operates at the correct working temperature; 5. Providing lubrication for the water pump, thermostat, and other components.
