Abstract
In an engine, a block-side flow path for circulating cooling water to cool a cylinder block, and a head-side flow path for circulating cooling water to cool a cylinder head are formed. A head-side outlet temperature of cooling water flowing out of the head-side flow path is adjusted by using a water pump that pressure sends the cooling water to both the block-side flow path and the head-side flow path. A block-side outlet temperature of cooling water flowing out of the block-side flow path is adjusted by a first thermostat that changes a flow amount of the cooling water flowing out of the block-side flow path. The cooling water flowing out of the block-side flow path is used as a heat source of first and second heater cores for heating air.
