<p>The present invention relates to an arrangement and a method for warming of coolant in a cooling system after a vehicle has been set in motion from cold. The arrangement comprises a control unit (22)adapted to assessing whether the coolant in the cooling system is at a lower temperature(TC) than an operating temperature(TD) and whether the air flowing through the coolant cooler(18) is at a temperature(TA1, TA2) which is higher than the coolant's temperature(TC), and, if these conditions are fulfilled, the control unit (22) is adapted to placing the valve means (17) in the second position so that the coolant is led to the coolant cooler(18), in which the coolant is warmed by the air flowing through the coolant cooler(18).</p> |
