Abstract
A cooling apparatus for an engine includes a main circuit, a warm-up circuit, a coolant passage, a coolant pump, a pre-branching passage, a coolant temperature sensor and an agitator. The warm-up circuit allows a coolant to bypass the main circuit. The coolant passage is provided inside an engine body. The coolant pump is configured to cause the coolant to flow through the coolant passage. The pre-branching passage is communicated with an outlet side of the coolant passage, and communicated with the main circuit and the warm-up circuit. The coolant temperature sensor is configured to detect a coolant temperature inside the pre-branching passage. The agitator is disposed downstream of the coolant temperature sensor in a direction of coolant flow when the coolant pump is operating. The agitator is disposed at a boundary between the pre-branching passage and the main circuit or in a vicinity of the boundary.
