Patent ID: 8439003

Claim:
A cooling apparatus for an internal combustion engine, comprising: an engine cooling system that includes a water jacket, a radiator, and a circulation passage through which a coolant is circulated between the water jacket and the radiator, wherein the coolant is provided in the engine cooling system; a water pump that forcibly circulates the coolant provided in the engine cooling system when the water pump is operated; a reservoir tank in which the coolant is reserved, and into which gas flows from the engine cooling system while the reserved coolant flows out from the reservoir tank to the water jacket via the radiator; and a control unit programmed to intermittently operate the water pump by controlling the water pump between an operating state and an off state at intervals of a predetermined time to forcibly introduce the coolant from the reservoir tank into the engine cooling system before the internal combustion engine is started, wherein the reservoir tank is connected to the radiator through an outflow passage and is connected to the water jacket through an inflow passage.
