Apparatus for supplying cooling air to an engine of a small vehicle wherein the engine includes a variable speed belt drive having a rotatable drive member that is connected to be rotated by the engine drive shaft. The air supply is driven by the drive member, and includes fan blades attached to the drive member, a casing around the blades, and ducts for conveying the cooling air to the engine. The engine may be either the air-cooled or the liquid-cooled type.
