Abstract

An engine system (140) includes an engine (12), a primary pump (14) coupled to the engine (12), and a motor (18) fluidly connected to the primary pump (14). The engine system (140) further includes a heat exchanger (28) fluidly connected to the engine (12), the heat exchanger (28) configured to accept heated coolant from the engine (12) and deliver cooled coolant to the engine (20). The engine system (140) also includes a fan (20) driven by the motor (18) in either a forward or a reverse mode of operation, the fan (20) configured to pull air toward the heat exchanger (28) in a first direction during the forward mode of operation to assist in cooling the coolant, and to push air toward the heat exchanger (28) in a second direction opposite the first direction during the reverse mode of operation. The engine system (140) further includes a controller (68) configured to operate the fan (20) in the reverse mode of operation in response to a sensed temperature of the coolant and a speed of the fan (20) in the forward mode of operation.
