A radiator fan assembly comprising:
- a fan;
- a shroud defining a fan opening aligned with the fan through which airflow from the fan passes;
- a flapper door opening defined by the shroud;
- and
- a flapper door pivotally mounted at the flapper door opening, the flapper door including a main body and an air guide extending from the main body;
- wherein the flapper door is mounted at the flapper door opening such that the air guide of the flapper door extends through the flapper door opening when there is no airflow through the fan opening.

A radiator fan assembly comprising:
- a radiator;
- a fan arranged to draw airflow through the radiator;
- a shroud defining a fan opening aligned with the fan through which airflow from the fan passes;
- a flapper door opening defined by the shroud;
- and
- a flapper door pivotally mounted at the flapper door opening such that when no airflow is passing through the flapper door opening a main body of the flapper door is on a side of the shroud that is opposite to the fan, and an air guide extending from main body extends through the flapper door opening;
- wherein:
- the flapper door is mounted such that when the fan is on, airflow from the fan contacts the air guide and moves the main body into the flapper door opening to close the flapper door opening;
- and
- the flapper door is mounted such that ram air passing through the radiator and the fan contacts the main body to rotate the flapper door away from both the radiator and the fan to open the flapper door opening and allow ram air to pass therethrough.
