Can't the two water pipes 10 above Santana throttle be installed backwards?

The function of these two pipes:

The water pipes at the side of 1. are used for waste gas backflow, reaching certain emission standards.

2. Water pipes are used to heat the throttle body. Because the climate in the north is cold. The air velocity at the throttle is large and it is easy to freeze in winter. In order to avoid this situation, hot water is pumped from the cylinder head to heat the throttle body, which belongs to a small cycle.

The throttle body is the valve that controls the intake of the engine. It is a circular steel plate with a shaft in the middle, which is connected with and controlled by the throttle cable.

Electronic throttle belongs to the throttle part of the intake system of automobile engine. It comprises a throttle body, a throttle valve plate, a throttle shaft, a DC motor, a gear reduction mechanism and a torsion spring, wherein one end of the torsion spring is fixed on the throttle body, and the other end is fixed on a gear of the throttle shaft.
