Abstract (en)
The present invention relates to a cooling system in a vehicle (1) powered by a combustion engine (2). The cooling system comprises a coolant pump (3) adapted to circulating coolant in the cooling system, and an expansion tank (12) which allows expansion of the coolant in the cooling system during operation. The cooling system has pressure-providing means (17-20) which make active pressurisation of the coolant in the cooling system possible close to at least one inlet to the coolant pump (3), and a control unit (21) adapted to receiving information which indicates when the pump starts and to activating said pressure-providing means (17-20) to create a positive pressure close to the inlet to the coolant pump (3) during a starting process of the pump.
