Abstract
A head cooling path diverges from a backflow path at a position between a radiator and a thermostat and is connected with a cylinder head of an engine by bypassing a cylinder block of the engine. A pump circulates the cooling water through the head cooling path, to the cylinder head, when the engine is operated at a high load and/or a vehicle is in a rapid acceleration, so that sufficiently cooled cooling water is supplied directly to the cylinder head.
