Can alcohol be added to car antifreeze?

[LaKimberly]

Alcohol should not be added to car antifreeze as it poses certain dangers. Alcohol is a flammable substance with strong volatility. The vapor it emits can form a combustible gas mixture with air, which may ignite when exposed to high heat or open flames. Even though the radiator is sealed, alcohol can vaporize in the pipes due to heat, and under the high temperatures of the engine block, there is a risk of explosion. 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 protecting against scale and corrosion year-round. It can be used in cars, train diesel locomotives, tractors, ships, engines, radiators, and various mechanical equipment.
