Abstract
A radiator fan arrangement for a vehicle which is powered by a combustion engine. The radiator fan arrangement includes at least one cooling element for cooling a medium, and a first radiator fan for continuously generating a forced air flow through at least one first region of the cooling element in order to cool the medium during operation of the combustion engine. The radiator fan arrangement also includes at least one extra radiator fan for being activated to generate an increased air flow through at least one second region of said cooling element in situations where the first radiator fan cannot provide sufficient air flow to cool as necessary the medium in the cooling element.
