Provided is a method for controlling the temperature of a cooling fluid in a cooling system comprising a cooling circuit connected to a condenser of a waste heat recovery system, a cooling pump arranged to circulate a cooling fluid through the cooling circuit and a radiator arranged for cooling the cooling fluid, a bypass circuit, a first and a second valve unit, wherein the first valve unit is arranged to control the flow of cooling fluid through the radiator and the bypass circuit, and the second valve unit controls the flow of cooling fluid passing through the condenser. A condenser-in temperature of the cooling fluid is determined by a first temperature sensor and an engine-in temperature of the cooling fluid is determined by a second temperature sensor. The flow of the cooling fluid is controlled by the first valve unit and/or the second valve unit based on the determined condenser-in and engine-in fluid temperatures.
