What is the initial action of the engine fan?

Explanation:
The fan’s first job is to pull air into the engine area. It creates suction at its inlet, drawing air through the grille and across the radiator to help remove heat from the coolant. It doesn’t compress air (that’s what a compressor does in a turbocharger), it doesn’t heat air (the cooling system aims to cool), and it doesn’t extract energy from exhaust (that would be a turbine). So, sucking air into the engine to start the cooling process is the correct action.
