How to judge the blockage of heater water tank?

1, check the warm air in the car, and blow the heat from the warm air small water tank into the cab with a blower. If the air volume is insufficient or the distribution of cold and hot air is not good, the heat of the small warm air tank will not be radiated, which will also cause the temperature of the warm air not to come up. At this time, first check whether the filter element is dirty or blocked, clean it, and replace it in time if necessary.

2. Check the operation of each gear of the blower, and each gear must reach sufficient speed. If the knob is set to the warm air position, the air volume is large enough, the wind direction is normal, and the cold air blows away. Check whether the outgoing line of the cold and hot air control panel of the control panel is disconnected, whether the heater impeller is damaged and whether the cover plate is disconnected. After troubleshooting, the warm air will become hot.

Matters needing attention in the use of automobile water tank:

1, use soft water, and use hard water after softening to avoid internal blockage and scale formation of radiator. When using antifreeze, in order to avoid radiator corrosion, please be sure to use long-term antirust antifreeze produced by regular manufacturers and in line with national standards.

2. In daily use, check the water level at any time, stop and cool before adding water. When adding water, please slowly open the cover of the water tank, and keep the operator away from the water injection port as far as possible to prevent high-pressure steam from spraying out of the water injection port and causing burns.

3. When the radiator is completely filled with water and then filled with water, be sure to turn on the drain switch of the engine block first, and then turn it off when there is water flowing out to avoid blisters.
