Abstract
There are provided a radiator passage, a thermostat to open and close the radiator passage according to an engine temperature, a heater passage, a flow adjusting device to adjust a flow amount of the coolant that flows in the water jacket according to the engine temperature at an engine start. The flow adjusting device is configured so as to adjust the flow amount of the coolant flowing in the water jacket to be a normal amount when the engine temperature is in an extremely-cold condition, to be zero or smaller than the normal amount when the engine is in a mild-cold condition, and to be the normal amount when the engine is in a warm condition. The heater passage is in opened sate at least when the engine is in the extremely-cold condition.
