A cooling arrangement for a WHR-system in a vehicle, includes a first cooling circuit including a first radiator (9) in which a circulating coolant is cooled, and a second cooling circuit including a second radiator (14) in which a coolant is cooled to a lower temperature than the coolant in the first radiator (9). A condenser inlet line (17, 38) directs coolant from one of the cooling circuits to a condenser (19) of the WHR-system, and a cooling adjusting device (13, 16, 24, 38) for adjusting the temperature of the coolant in the inlet line (17, 38) to the condenser (19) by the coolant in the other cooling circuit. An arrangement (37, 24) receives information about the cooling to estimates cooling for the working medium in the condenser (19) controls the adjusting arrangement (13, 16, 24, 38) such that the coolant in the condenser inlet line (17) provides the estimated suitable cooling of the working medium in the condenser (19).
