Most fan manufacturers supply only part of the fan: e.g. motor, fins, or bearings, and this can make fan repair and replacement a time-consuming and challenging task. Nissens supplies complete fan solutions, ready for installation, and the fans fit perfectly to both Nissens' radiators and OE radiators. A Nissens fan even fits a number of different radiator models, and all fans are manufactured from quality materials and tested as complete units. This means that the fan is properly balanced, and that effect, functionality, and reliability are ensured.
