If the heating box leaks, you must remove the workbench. If you don't take it off, you can't take it off at all. There are three reasons why the heater tank leaks:
1, first of all, the material of the warm air tank itself is not good, resulting in a short service life;
2. The second is welding technology. If the heater water tank has been repaired before, and then it leaks, then this is the reason;
3. The third is that the factory inspection is not strict enough and the inspection is not detailed enough, which leads to the problems of the components themselves.
It depends on the model. Some models need to remove the entire central control instrument and replace the heater box. Some models have been designed with the problem of replacing the heater box in the later stage in mind, and the heater box will be replaced without removing the instrument panel.
If the vehicle needs to replace the heating box, it is necessary to remove the workbench. This requires professional tools to remove the screws first, and then step by step in order.
