ENGINE COOLING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an engine cooling apparatus that can suppress an increase in manufacturing costs and is hardly restricted in arrangement of a flow control valve.SOLUTION: An engine cooling apparatus includes: a coolant circuit 3 including a head coolant channel 1 for cooling a cylinder head E1 of an engine E and a block coolant channel 2 for cooling a cylinder block E2 in parallel each other; a circulation pump P for circulating a coolant of the coolant circuit 3; a state detection sensor S for detecting an operation state of the engine E; a pump control device C for increasing and decreasing a discharge amount of the circulation pump P on the basis of a result detected by the state detection sensor S; and a flow control valve V provided in the middle of the block coolant channel 2 and having a valve body that can be moved to a valve opening side by a water pressure of the coolant and a biasing member for biasing the valve body to move to a valve closing side.
