A vehicle radiator air intake screen maintenance system comprising a radiator fan, a fan motor; and a control module operable to control the rotational speed and direction of the radiator fan to: periodically implement a drop cycle whereby a radiator cooling air flow generated by the fan rotating in a forward direction is slowed such debris collected on a radiator air intake screen of the vehicle is caused to fall off due to gravitational force; and periodically implement a full reverse cycle where a rotational direction of the fan is reversed and an expulsion air flow is generated whereby debris collected on vehicle radiator and the air intake screen will be blown off, whereafter reverse rotation of the fan is stopped and the fan is returned to the full forward operating speed and direction.
