Can You Still Drive If the Car's Antifreeze Level Is Below the Minimum Mark?

If the car's antifreeze level is below the minimum mark, you should not continue driving and need to add antifreeze promptly. Functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and providing year-round protection against scale and corrosion. Methods to determine if antifreeze is insufficient: Observe the antifreeze warning light on the dashboard. If it lights up, it likely indicates a lack of antifreeze, though it could also be due to excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), antifreeze should be added promptly. Inspect the water level scale markings on the antifreeze overflow tank. The normal antifreeze level should be between the maximum and minimum marks. Whether antifreeze is lacking depends on the scale; if it's below the minimum mark, it indicates a deficiency.
When I find the antifreeze level below the minimum mark, it's best not to continue driving. The engine relies on antifreeze for cooling, and if the level is too low, the cooling efficiency drops, which may lead to engine overheating or even cylinder damage—a costly repair. Last time I noticed the temperature gauge rising rapidly on the road, I immediately turned off the engine to check and found the level was off. When topping up, make sure to use the same type of antifreeze; avoid mixing different brands as it could corrode the system. If there's a repair shop nearby, driving there at low speed for a short distance might be acceptable, but the risk is high—calling a tow truck is the safer option. Regularly checking the coolant level and color is a key preventive measure, especially for older cars that are prone to leaks or evaporation. Remember not to ignore the dashboard warning lights; a small oversight can lead to big trouble.
