Abstract:
1. A water-cooled type engine cooling apparatus comprising: an oil cooler adapted to circulate cooling water flowing out of a water-cooled type engine so as to regulate temperature of hydraulic oil for an automatic transmission by exchanging heat of the hydraulic oil with heat of the cooling water; a water temperature detection unit adapted to detect temperature of the cooling water; a switching unit capable of switching the oil cooler from an operating state, where the cooling water circulates through an oil cooler body of the oil cooler, to a halt state, where the cooling water is prevented from circulating through the oil cooler body, and vice versa; and a switching control unit adapted to control switching of the switching unit; wherein the switching control unit controls the switching unit to switch the oil cooler into the halt state when the temperature detected by the water temperature detection unit is lower than a preset temperature, and controls the switching unit to switch the oil cooler into the operating state when the temperature detected by the water temperature detection unit is not lower than the preset temperature.
