ABSTRACT:
In a method of making a motor vehicle radiator, extruded hollow shapes of oval cross section provided inwardly with at least one longitudinally extending web 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 is of light metal with a substantial oval cross section.
