An improved cooling system for a vehicle engine and retarder has independent parallel cooling circuits (7, 8) for the engine and retarder and with a common radiator (9). The retarder (6) also operates as a pump for the retarder cooling circuit. Both the cooling circuits are connected to parallel ducts in the oil cooler (11) for the transmission, to provide transmission cooling independent to the engine temperature. The retarder cooling circuit also operates at a low flow level during normal traction. The engine cooling circuit is controlled by a conventional thermostat and shunt.
