A method and system for cooling system an electrical vehicle (EV, HEV, hybrid) comprises a radiator, 120, for cooling the prime mover, 110, (electric machine, motor). An air moving means, 128, is used to create an air flow, 124, across the radiator to remove heat therefrom. Air having passed the radiator is redirected via an air duct, 150, across the transmission, 102, (drivetrain, gearbox) of the vehicle. The air may be directed to the underside of the transmission. The air moving means be a fan, 134. There may be a control means, 160, for altering the rotation speed of the fan. The control may be based on the output from heat or temperature sensors, 170. The control may be based on route planning (gps, navigation, sat nav) data, whereby, for example if the speed of the vehicle is expected to rise then the fan speed may be lowered.
