An arrangement and a method for warming coolant in a cooling system of a combustion engine for instance in vehicle: A control unit (22) assesses whether the coolant is at a lower temperature (TC) than an operating temperature (TD) and whether air flowing through the coolant cooler (18) is at a temperature (TA1, TA2) higher than the coolant's temperature (TC). If the assessing determines that those conditions are satisfied, the control unit (22) places a valve (17) in a second position to lead the coolant to the coolant cooler (18), for warming the coolant by air flowing through the coolant cooler (18).
