Changing from a vertical to a horizontal radiator is not a trivial matter: the air flow, which normally affects the radiator front, would now affect it at an angle, which means it could not cool the water in the circuit. The air conveyor thus becomes the determinant factor. Made of fiberglass with high bending characteristics, it is placed under the radiator and deflects the flow by 90° from horizontal to vertical, directing it towards the aluminium grid where the cooling circuit water flows. The conveyor has two switches, one at the front and one at the end of the radiator, for better distribution of the air flow over the surface of the air and liquid heat exchanger. An upper flap is also mounted on the radiator that creates a depression in accordance with the laws of fluid dynamics, which and optimises the flow of air. Should the cooling power instead be reduced, you can use the classic sliding curtain positioned in place of the flap.

Mounting the new New Line horizontal radiator is simple, although the process is obviously different from the usual one. The bracket that fastens the rear conveyor has to be mounted first, which in turn will be blocked at the front with cable ties. Then the radiator is mounted, positioning it inside the conveyor. During the first assembly it is necessary to make the holes for the bolts that connect the radiator to the conveyor.

The benefits of the horizontal radiator are above all aerodynamic. The first is the smaller front section that gives a much higher drag coefficient. In fact, while a traditional radiator has a height of 41-45 cm, depending on the angle, the horizontal axis reaches a maximum of 24 cm in relation to the chassis. Despite the fact that the air flows are very turbulent for karts, a 50% reduction in penetration resistance can be assumed. The second benefit relates to the brake and the left rear wheel, critical elements for the high temperatures they can normally reach, since they are covered and take a reduced air flow, as well as being heated by the passage of the air through the radiator grille. Overheating reduces braking power, increases wear of the brake pads, abnormally deteriorates the tread and badly affects performance and grip. The flow to the rear is cleaner and the area more open with a horizontal radiator. In particular, it avoids the blister that forms on the wheel, generally at temperatures above 110°C.
