How does Jiangling Collection (diesel pickup truck) warm the warm wind in winter in Northeast China?

It seems that the warm wind is not hot, which is a common problem of Jiangling! Qingling is much better. There is no good way, such as blocking a layer in front of the car head and blocking a paper shell in front of the water tank, which are not ideal. After the fan is removed, the high speed is still high, so it is better to block it below. If it doesn't catch fire, you can only add a preheater or try to choose a leeward place when parking. Check glow plug.
