Abstract
A cooling system for a vehicle power unit has a cooling fan rotated by the rotational force from the crankshaft, in the housing thereof so as to cool the internal space of the housing by introducing air into the housing and discharging the thus introduced air to the outside through upper and lower outlet ports. The upper side outlet port is formed in the housing upper surface opposing the approximate middle portion of the V-belt's return path along which the V-belt moves from the rear to the front so as to promote the current of air introduced in the housing to flow along the direction of travel of the V-belt.
