  "textContent": "A system for operating a cooling device of a utility vehicle includes an axial fan, a temperature sensor, and a control unit. The axial fan can be rotated by a fan drive and is used to generate a cooling air stream for impingement on a vehicle assembly that is to be cooled. The axial fan has a plurality of fan blades that can be pivoted in terms of an angle of incidence by deflection of an actuator. The temperature sensor determines an actual value of a temperature variable that reflects a present operating temperature of the vehicle assembly. The control unit compares the actual value of the temperature variable with a specified setpoint value to output a target value of a control variable provided for the operation of the actuator. The control variable is one of a hydraulic and a pneumatic operation pressure for deflecting the actuator.",
