In a few sentences

In brief

It serves the heat exchange, not the circulation of the liquid.

Useful to know

The radiator fan creates an airflow for the cooling. HELLA describes it as part of maintaining the operating temperature other than the pump that moves the liquid. [1]

In a schematic, it tracked the air and the cooling circuit separately. Turning the fan does not prove that all parts of the system are working. Do not approach the fin for inspection; the controlled trigger may be independent of your expectations. The exact on and off behavior is determined by the vehicle and its operating conditions.
