What Causes the Decrease in Car Antifreeze?

[EllieRose]

Reasons for the decrease in car antifreeze include antifreeze entering the cylinder, thermostat malfunction, leaks in the radiator cap, radiator, or water pump, and excessive natural consumption. Functions of antifreeze: Antifreeze is a coolant with special additives, primarily used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. Methods to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze, though it could also be caused by excessively high cylinder temperature. Check the antifreeze reservoir. If the level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level markings on the antifreeze bottle. The normal antifreeze level should be between the maximum and minimum marks. To determine if antifreeze is low, check the markings. If the antifreeze is below the minimum mark, it indicates a shortage.
