A cooling module includes multiple heat exchangers, at least one of which is a coolant radiator. The cooling module further includes a structural frame channel extending along an end of the cooling module, with the heat exchangers being at least partially secured to the structural frame channel. A coolant surge tank is integral to the cooling module, and is in fluid communication with the coolant radiator. The coolant surge tank has a coolant volume bounded by several walls, and at least one of those walls is provided by the structural frame channel. A method of making the cooling module is also described.
