The heater water tank of Yutong bus is located in the middle behind the instrument panel, which can only be seen when the instrument panel is removed. The hot water tank is installed at the position where the hot water pipe behind the engine leads to the instrument.
The warm air tank is just a heating component in the hot air conditioning system. When the water in the engine passes through the warm air tank, the warm air tank is heated, and the fan works to blow against the warm air tank. When the wind passes through the warm air tank, it is warm air.
