Will the antifreeze decrease when using air conditioning in summer?

[LeJuliette]

Using air conditioning in summer will not cause the antifreeze level to decrease; it is only related to fuel consumption and stored battery power. The antifreeze used for engine circulation cooling will not be reduced due to the use of air conditioning or heating. Functions of antifreeze: Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and resisting 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, although it could also be caused by excessively high cylinder temperature. Check the antifreeze reservoir. If the liquid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Check the water level scale on the antifreeze bottle. The normal antifreeze level should be between the maximum and minimum marks. Whether antifreeze is lacking depends on the scale. If the antifreeze is below the minimum mark, it indicates a shortage of antifreeze.
