An attachment member may couple a radiator to a grille of an automotive vehicle. The attachment member may be easily fit into a complementary grille opening on the grille. The complementary shapes of the attachment member and the grille opening may limit movement of the attachment member relative to the grille in one or more directions. The attachment member may install from above the grille opening or horizontally slide into the grille opening. Engagement features on the attachment member may engage with surfaces of the grille opening to limit relative vertical movement. The attachment member may provide a first engagement with the grille at a first level and a second engagement with the radiator at a second level different than the first level.
