Abstract: A motor vehicle cooling fluid flow pipe, such as an engine cooling fluid pipe, characterized in that the wall of the pipe is constituted by a single layer made of a polymer material comprising a mixture of at least two polymer materials of different natures, one of which, referred to as a first material, being a polyolefin, and the other of which, referred to as a second material, being a thermoplastic polymer elastomer (TPE). The method of manufacturing this pipe comprises an operation of mixing at least the polyolefin and the thermoplastic polymer elastomer (TPE), a step of extruding said mixture in a screw extruder followed by a step of forming the pipe, the operation of mixing the polyolefin and the thermoplastic polymer elastomer (TPE) being performed upstream from the extruder or at its inlet.
