Puller fans mount on the engine side (back) of the radiator core and pull air through the radiator core. The fresh airflow is pulled through the grille, then pulled through the core, and exits out the back side of the radiator. Puller fans are the desired and most common way of mounting a fan when space is not a limitation between the front of the engine and the back of the radiator core.
