Abstract
A cooling apparatus for vehicle includes a radiator, a coolant pump, a cooling fan, first and second mode controllers, and an abnormality diagnosing controller. The radiator cools a coolant that circulates through a circulation flow channel of a cooling system. The coolant pump causes the coolant to circulate through the circulation flow channel. The cooling fan faces the radiator. The first mode controller initiates a first operation mode process upon diagnosing an abnormality of the cooling system. The first operation mode process stops the coolant pump and drives the cooling fan. The second mode controller initiates a second operation mode process after completion of the first operation mode process. The second operation mode process stops the cooling fan and drives the coolant pump. The abnormality diagnosing controller diagnoses, based on a temperature of the radiator, the abnormality of the cooling system after the initiation of the second operation mode process.
