ABSTRACT:
A cooling system includes a coolant distributing device arranged to distribute coolant discharged from a water pump to both an engine and a transmission device. The coolant distributing device includes a coolant relay section, an inlet conduit member, an outlet conduit member, and a transmission cooling conduit member, and supplies a portion of the coolant discharged from the water pump to a highest portion of a water jacket of the transmission device, and discharges the water from a lowest portion of the water jacket. The cooling system effectively cools the transmission device with a simple construction facilitating assembly and maintenance.
