The invention relates to a heat exchanger mounting bracket which has a first member with a retaining channel and a second member with a retaining lug. The retaining channel of the first member retains the retaining lug of the second member at an initial mounting position, with a predetermined retaining force, by way of at least a formation on the first member. The retaining channel and lug are releaseable from one another when a force greater than or equal to the predetermined retaining force is applied between the first and second members. A heat exchanger mounting bracket is also provided where a body member is provided with a longitudinal slot toward one end for locating a portion (P) of a heat exchanger, and a pivotal arrangement toward the other end. The pivotal arrangement and longitudinal slot allow displacement of the portion (P) of the heat exchanger from a fore to an aft position upon application of an impact force.
