Zusammenfassung:An EGR cooler system according to the invention includes an EGR cooler cooling device that is provided in a coolant path which is separate from the path provided with an engine cooling system which cools coolant. The EGR cooler cooling devices cools the coolant to be supplied to a water-cooled EGR cooler. The EGR cooler system also includes a water pump that circulates the coolant within the coolant path; a bypass passage through which the coolant may bypass the EGR cooler cooling device or the water-cooled EGR cooler; and a flow control valve that regulates the amount of coolant flowing into the bypass based on the temperature of the coolant flowing through the coolant path.
