Is it acceptable to add a small amount of alcohol to antifreeze?

Adding a small amount of alcohol to antifreeze is not acceptable and poses certain risks. Alcohol is a flammable substance with strong volatility. The vapor it emits can form an explosive combustible gas mixture with the atmosphere, which may ignite or explode if exposed to high heat or open flames. Antifreeze, fully known as antifreeze coolant, is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. Its components include calcium chloride, methanol, ethanol, ethylene glycol, glycerol, etc. The functions of antifreeze are: 1. Providing anti-corrosion protection for cooling system components; 2. Preventing scale formation to avoid reducing the radiator's heat dissipation efficiency; 3. Ensuring the engine operates within the normal temperature range.
Adding alcohol to antifreeze is absolutely not acceptable. As someone who frequently repairs cars, I know this is very dangerous. Alcohol has a low boiling point, and adding it to the cooling system can easily cause engine overheating and cylinder explosion, increasing repair costs. It corrodes rubber seals and hoses, leading to leaks, which are troublesome and expensive to fix. Alcohol evaporates quickly, making its concentration unstable and reducing its antifreeze effectiveness, potentially freezing and damaging pipes in winter. Modern antifreeze contains specialized additives to prevent corrosion and stabilize the boiling point. It's recommended to directly purchase and replace it with a proper product. Regularly check the color and level of the coolant to ensure it's within the standard range for peace of mind. Saving a small amount of money isn't worth the risk—engine problems can result in repair costs ten times higher than what you saved. Safety comes first; don't follow old folk remedies. Just go through professional channels for handling it.
