Will the water in a four-wheeled vehicle's radiator freeze at -3 degrees Celsius?

Whether the water in a four-wheeled vehicle's radiator will freeze at -3 degrees Celsius depends on the type of solution inside the radiator. If the radiator is filled with tap water or distilled water, it will freeze at -3 degrees Celsius, especially if the vehicle is parked for an extended period, leading to more severe freezing. However, if the radiator contains automotive-specific antifreeze, it will not freeze. Freezing point of antifreeze: Automotive antifreeze is typically blue or pink and has a freezing point of -30 to -35 degrees Celsius. Even when mixed with water, the freezing point remains at least -10 to -15 degrees Celsius. It is important to regularly check the antifreeze level during routine vehicle use and top it up when necessary. Avoid adding liquor: Many mechanics use a mixture of water and alcohol as a substitute for windshield washer fluid. However, alcohol has a low boiling point and is highly volatile when heated. The vapor it releases can form a "flammable mixture" with the air, posing a significant risk of explosion and combustion if exposed to high heat or open flames.
