What is the German translation for "coolant"?

The German translation for "coolant" is "Kühlflüssigkeit." This term is derived from "Kühl," meaning "cool," and "Flüssigkeit," meaning "liquid." Together, they accurately convey the concept of a fluid used to remove heat in various applications, such as in engines and cooling systems.

The other options do not relate to the term "coolant." For example, "Haube" translates to "hood" or "cover," which refers to a protective covering, often used in automotive contexts but not related to temperature regulation. "Hahnenfuß" means "rooster's foot," which has no connection to cooling systems. Lastly, "Trümmer" translates to "debris" or "wreckage," which again does not pertain to the function of cooling fluids. Therefore, "Kühlflüssigkeit" is the appropriate choice for the translation of "coolant."
