Zusammenfassung:	An engine cooling fan control strategy includes measuring an engine coolant temperature using a sensor connected to the engine, measuring an engine oil temperature using a sensor connected to the engine, selecting a first value from a maximum engine coolant temperature threshold calibration curve stored in the control system based on the engine oil temperature, selecting a second value from a minimum engine coolant temperature threshold calibration curve stored in the control system based on the engine oil temperature, and placing the engine cooling fan in driven relationship with the engine when the engine coolant temperature exceeds the first value, and placing the engine cooling fan in non-driven relationship with the engine when the engine coolant temperature drops below the second value.
