Abstract
A vehicle includes a radiator, a bypass passage, a first valve, a second valve, and a controller. Cooling water is circulated through the radiator independently of a cylinder block and a cylinder head of an engine. The radiator cools the cooling water. The cooling water is circulated through the bypass passage while bypassing the radiator. The first valve switches between an open state in which cooling water is circulated through the cylinder block and a closed state in which cooling water is not circulated through the cylinder block. The second valve receives cooling water circulated through the cylinder head and cooling water circulated through the cylinder block via the first valve. The second valve uses an intermediate opening to adjust a flow rate of cooling water circulated through the radiator and the bypass passage. The controller controls opening and closing of the first valve and the opening of the second valve.
