    Abstract: There is provided a combined cooling and water braking system (200) for a vehicle (1, 20). The system comprises a first water recirculation loop (220) having a first heat exchanger (222) configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device (210) configured to generate a propulsion power for the vehicle. A second water recirculation loop (230) having a second heat exchanger (232) is configured to cool water flowing in the second water recirculation loop. A retarder (250) is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle. The invention additionally relates to a computer program, a computer readable medium and a control unit related to said method.
