| Evaporation of glycol Ethylene glycol antifreeze does not evaporate. If you put an open container on the sofa, it is so hygroscopic that it quickly absorbs water. It is also strongly absorbed by the cellulose of the wood.
Water turns into steam at 212 ° F. Mixing traditional ethylene glycol based antifreeze with water in a ratio of 5050 raises the boiling point to 223 ° F, which is close to the operating temperature of an engine. Evans waterless coolants boil over 375 ° F, well above the engine’s operating temperature.
When your car’s coolant expands in hot weather, it is expelled from the coolant overflow tank radiator or drain tank. This hot coolant in this overflow tank will slowly evaporate and slowly lower the coolant level.
Most vehicles lose coolant over time due to evaporation from the reservoir. However, a large coolant leak in a relatively short period of time usually indicates a leak, an unpressurized radiator cap, or an overheated cooling system.
It is normal for ALL CARS to leak a small amount of coolant during an oil change interval. This is also normal! You are beautiful.
Eventually it evaporates into an icy white spot. to
