Abstract: A cooling system in a vehicle includes a cooling fluid pump (3) that circulates cooling fluid in the cooling system, a cooler (5) for the cooling of the cooling fluid, and a valve (10) to lead cooling fluid to the cooler (5) for cooling or to a return line (13) without cooling. A first circuit (6) includes cooling channels (6a) for the cooling of the combustion engine (1) and a second circuit (17) for the cooling of a hydraulic retarder. The first circuit (6) leads cooling fluid from the cooling fluid pump (3) to a first inlet (10c) at the valve (10). The second circuit (17) leads cooling fluid to a second inlet (10d) at the valve (10). In operating conditions in which the hydraulic retarder is not activated, the valve (10) blocks the second inlet (10d) and thus the circulation of cooling fluid through the second circuit at the same time that it receives cooling fluid from the first circuit (6) through the first inlet (10c).
