Claim 4:
5. The EGR system of claim 2, wherein:
the heat exchange system further comprises a heat exchanger bypass valve;
in response to the heat exchanger bypass valve being in an open position, the coolant return line is configured to be in direct fluid communication with the coolant supply line such that coolant fluid bypasses the heat exchanger and flows directly from the coolant return line to the coolant supply line; and
in the controlling of the heat exchange system, the ECM is further configured to open the heat exchanger bypass valve in response to comparing the temperature of the exhaust-air mixture to the dewpoint temperature and determining that the temperature of the exhaust-air mixture is below the dewpoint temperature.
