Abstract

A cooling system of a motor vehicle may include a coolant circuit including an exhaust-gas recirculation path and an exhaust-gas recirculation cooler arranged therein. A pressure detection device may be provided for detecting a coolant pressure in the coolant circuit. An actuating device may be connected communicatively to the pressure deduction device. A valve device may be connected communicatively to the actuating device and configured to control an exhaust-gas stream passing into the cooler. The actuating device may be configured to at least partially close the valve device and reduce the exhaust-gas stream flowing to the cooler in response to the pressure detection device detecting a predefined pressure drop.
