How to change the small heater water tank of Audi a6 in 2005?

In 2005, the replacement of Audi a6 heating box needed to go to 4S shop or repair shop to replace the heating box, so as not to damage the heating box components.

The blockage of the heater water tank is also a possible reason why the heater is not hot. The structure of the warm air water tank is actually a miniature version of the radiator of the engine water tank, and there are many small cooling pipes in it, which are as easy to block as the radiator of the water tank.

The lack of antifreeze in the cooling system is the most common reason why the warm air is not hot. When designing the engine cooling system, engineers will give priority to engine heat dissipation, and then the warm air can work normally. When the coolant is insufficient, the coolant will circulate in the engine first. At this time, there is no "water" in the warm air circulation pipeline, and most of the warm air tank is gas. At this time, the air conditioning warm air is naturally not hot.

Extended data:

The water tank of Audi a6 heater in 2005 is introduced as follows:

First of all, we should know two working principles of automobile heating. The first method is to concentrate the temperature generated by the engine operation, and then send the heat into the car through the blower to achieve the heating effect. This way is also the most energy-saving way, and it will not increase the additional fuel consumption.

If you want to use the engine temperature to turn on the warm air, it is best to turn on the warm air after the car starts for a period of time, because if you turn on the warm air when the car is cold and turn on the automatic air conditioning mode, even if the AC key is not turned on, the car system will automatically switch to the air conditioning compression mechanism, which will increase fuel consumption.
