Typical cooling modules for motor vehicle engines consist of a coolant radiator and a charge air cooler arranged in parallel. The coolant radiator and the charge air cooler are fixedly coupled to one another by a hinge-type connection of their feed cases. The present invention assigns a connection piece to the feed case of one of the coolers, which connects the fin/tube block on one side. The connection piece projects toward the other cooler and form-lockingly engages in a fastening opening on the feed case of the adjacent cooler. This connection piece is provided approximately in the center between two additional outer fastening points, so that a stable block is formed by the two feed cases. This is sufficient to uniformly distribute asymmetrically introduced forces to both coolers and thereby avoid overloading on one cooler.
