  • Patent number: 8539915
    Abstract: A cooling system for motor vehicle with a cooling circuit, which includes one or more internal combustion engines, a pump and a cooling device, is described herein. The cooling system includes a short circuit line, which bypasses the pump by connecting a pressure side of the pump to an intake side of the pump. The cooling system further includes a valve device in the region of the short circuit line, and the valve device is switched between two or more positions. When the valve is in the first position, the entire coolant flow is directed through the short circuit line. Further, when the valve is in the second position, the entire coolant flow is directed through the internal combustion engine and not through the short circuit line.
