Jianghuai Ruifeng auxiliary water tank will have pressure no matter how cold the car is.

This is a normal phenomenon. JAC Ruifeng has launched three influential car combinations, including the flagship new product of Ruifeng series extending to high-end MPV-Ruifeng Xianghe. It is normal for JAC Ruifeng's auxiliary water tank to be cold, because the engine will generate high temperature when working, and the coolant will expand at high temperature, while the engine cooling system pipeline is closed.
