At higher altitudes, what is used to cool down aircraft engines?

Posted by: Brad Lithium  /  Category: Aircraft



Water is used as a coolant for cars. Which fluid is used for jet engines? Someone told me it was water. Someone else told me it cannot be water because water freezes at higher altitudes. So which fluid is it?

Thanks!

P.S: I know air is partially used to cool down the engine, but i’m sure bypass air is not the only fluid cooling down the engine.
