Method of making a motor vehicle radiator in which extruded hollow shapes (1) of oval cross-section provided inwardly with at least one longitudinally extending web (2) lying transversely of the larger major axis of the oval cross-section, are reshaped, e.g. rolled under pressure to a cross-sectional form of a flat profile tube having two parallel sides, soldered to cooling fins and fitted into a radiator housing. The extruded hollow shape (1) of light metal with a substantial oval cross-section for use in this method comprising inwardly at least one web (2) which extends in the longitudinal direction of the shape (1) and transversely to the large major axis of the oval cross-section of the shape. |
