Abstract
An arrangement for cooling oil in a gearbox in a vehicle which is powered by a combustion engine, the arrangement including an oil cooler, an oil system configured to circulate oil between the gearbox and the oil cooler, and a coolant circuit configured and operable to lead coolant to the oil cooler. The coolant circuit includes a radiator element for cooling the coolant and a line to lead the cooled coolant from the radiator element to the oil cooler. The coolant circuit has a flow-regulator to regulate the coolant flow through the radiator element for imparting to the coolant a temperature which makes possible a desired cooling of the oil in the oil cooler.
