A work vehicle includes an engine, an exhaust gas purification apparatus, a reducing agent tank, an engine coolant circuit, a branch path, a valve, an accepting portion, a valve control unit, a fan, a radiator, a thermostat, and a fan control unit. The valve control unit gives an instruction for an opening operation of the valve in response to the operation instruction from the operator accepted by the accepting portion. The fan generates cooling wind in an engine room. The radiator cools the engine coolant with the cooling wind. The thermostat is provided between the circulation path and the radiator and operates to open for supplying the engine coolant to the radiator when a temperature of the engine coolant is equal to or higher than a prescribed temperature. The fan control unit increases the number of rotations of the fan in response to the operation instruction. |
