Abstract: Disclosed is a cooling system comprising a cooling circuit with a deaeration device arranged in the cooling circuit for separation of air bubbles from coolant circulating therein. The deaeration device comprises a deaeration chamber having a coolant inlet connected to a feed pipe of the cooling circuit, a first coolant outlet connected to a coolant pump of the cooling circuit, and a second coolant outlet connected to an expansion tank via a static line. The deaeration chamber has a larger cross-sectional dimension than said feed pipe. The second coolant outlet is located in such a position in relation to the coolant inlet and the first coolant outlet that the coolant flow in the deaeration chamber between the coolant inlet and the first coolant outlet will move migrating air bubbles in the longitudinal direction of the deaeration chamber towards the second coolant outlet.
