Zusammenfassung:	To prevent a vapor failure of fuel after an ignition switch is off, without giving long-time operation to an electric fan.SOLUTION: In front of an engine 1, a radiator 40, an electric fan 50, and a grille shutter 60 are provided. When the engine 1 is stopped, the grille shutter 60 is basically subjected to closing operation to reserve the heat of the engine 1. When the engine 1 is stopped, if the temperature of cooling water or the temperature of fuel itself is high, the electric fan 50 is allowed to operate and the grille shutter 60 is subjected to opening operation. The grille shutter 60 subjected to the opening operation is then subjected to closing operation, for example, on condition that each of the temperature of the cooling water and the temperature of the fuel lowers down to a predetermined temperature.SELECTED DRAWING: Figure 8 【課題】イグニッションスイッチがオフされた後における燃料のベーパ障害の発生を、電動ファンを長時間作動させることなく防止できるようにする。【解決手段】エンジン１の前方に、ラジエータ４０、電動ファン５０に加えて、グリルシャッター６０が設けられる。エンジン１を停止させたときには、基本的にグリルシャッター６０が閉作動されて、エンジン１の保温が図られる。エンジン１を停止させたときに、冷却水温度あるいは燃料そのものの温度が高いときは、電動ファン５０が作動されると共にグリルシャッター６０が開作動される。開作動されたグリルシャッター６０は、例えば、冷却水温度と燃料温度との双方が所定温度まで低下していることを条件として、閉作動される。【選択図】図８
