Abstract
Heat exchanger apparatus for a motor vehicle engine comprises a main heat exchanger having a water box containing a secondary heat exchanger that includes two coupling tubes, which extend sealingly through a side wall of the water box. The secondary heat exchanger is secured in the latter by means of these tubes, each fitted to the secondary heat exchanger by being introduced successively through an access orifice formed in the water box side wall and then into a seating formed in the secondary heat exchanger. The water box side wall carries at least one slide inside the water box, and the secondary heat exchanger has at least one sliding element which slides in the slide so as to enable the secondary heat exchanger to be precisely positioned within the water box, so that the two coupling tubes can then be fitted.
