What Happens If a Car's Radiator Runs Out of Water?

[MarleyAnn]

If a car's radiator runs out of water or has insufficient coolant, it can cause the engine to overheat and damage internal components. In severe cases, this may even lead to complete engine failure. An automobile engine must be properly cooled to maintain optimal operating temperature, ensuring good performance, durability, and meeting exhaust emission requirements. Note that the "water" in the radiator refers to antifreeze coolant. Key information about antifreeze is as follows: 1. Antifreeze is a specially formulated coolant additive primarily used in liquid-cooled engine cooling systems. It provides winter freeze protection, summer boil-over prevention, year-round scale inhibition, and corrosion resistance. 2. Over 95% of modern antifreeze solutions worldwide use ethylene glycol-based formulas. Compared to plain water, ethylene glycol's most notable feature is freeze protection (which water cannot provide). Additionally, ethylene glycol has a high boiling point, low volatility, appropriate viscosity with minimal temperature variation, and excellent thermal stability. Therefore, ethylene glycol-based antifreeze represents an ideal cooling solution.
