ABSTRACT:
A cooling device for an internal combustion engine includes a communicating passage for communicating the inlet and outlet of a water pump, a cooling water temperature detecting means for detecting the temperature of cooling water for the engine and a valve controlled by the cooling water temperature detecting means for opening the communicating passage when the cooling water temperature is lower than a predetermined value and closing the passage when the temperature is higher than the value, so that when the engine is at a lower temperature the cooling water is not circulated through a cylinder block and a cylinder head of the engine, thereby rapidly raising the temperature of the engine to remarkably improve the exhaust gas characteristics and running performance and reduce the fuel consumption.
