Self-propelled road milling machine with a cooling system

Self-powered road surface milling machine has an air-blown (36) cooling system with a radiator (34) and a suction air duct (38, 40). The air duct has an air inlet (46, 48) and an outlet (42, 44) directed at the radiator along the machine longitudinal axis, sucking in air from the side. In a preferred embodiment, the suction passage is fabricated as a single unit with the liquid holding tank (32).
