A cooling system (2) disclosed herein includes a first system flow passage (10), a second system flow passage (20), and a reserve tank (100). The reserve tank (100) includes a first chamber (111), a second chamber (112), a third chamber (113) and fourth chamber (114), and an intermediate chamber. A first inflow port (101) is opened into the first chamber (111), a first outflow port (102) is opened into the second chamber (112), a second inflow port (103) is opened into the third chamber (113), and a second outflow port (104) is opened into the fourth chamber (114). The first chamber (111) and the second chamber (112) communicate, the third chamber (113) and the fourth chamber (114) communicate, and the first chamber (111) communicates with the third chamber (113) through the intermediate chamber. The first system flow passage (10) is connected to the first inflow port (101) and the first outflow port (102), and the second system flow passage (20) is connected to the second inflow port (103) and the second outflow port (104).
