Abstract
An engine cooling system includes a two-pass radiator having multiple cores and a hydraulically-operated motor located between the cores. The motor drives a cooling fan that blows air against the radiator. Also, oil coolers are located between the cores to cool oil that is used to actuate the motor. With this structure, the space in the axial dimension that is consumed by the radiator with fan and fan motor is minimized.
