An engine cooling apparatus includes a coolant inlet of a block water jacket formed in a cylinder block, wherein coolant is introduced into the block water jacket through the coolant inlet, a flow-directing plate that is disposed in the block water jacket at a position downstream of the coolant inlet, and that directs the coolant, which has been introduced into the block water jacket through the coolant inlet, toward a head water jacket and a control portion that controls inflow of the coolant from the head water jacket into the block water jacket.
