How to replace the heating flap of Volkswagen new Jetta 1.6l

If the new Volkswagen Jetta 1.6l needs to replace the heater chip, it must be operated in the 4S shop or repair shop of the car, and it cannot be handled by itself, which will damage the heater parts of the car.

The heat source of the warm air in the car is the afterheat of the engine, so it is the water temperature of the engine that determines whether the warm air is hot or not. If the engine water temperature is low, the warm air will not be hot. If the warm air is not hot, observe the engine water temperature first. If the water temperature is low, the temperature rises slowly, or only stays at about 40 degrees, the thermostat should be the most suspicious.

If the thermostat is damaged and not closed properly, the engine cooling system will always be in a state of large circulation, and the heat generated by the engine will be quickly dissipated by the water tank at any time, resulting in slow temperature rise of the coolant and low water temperature. If the engine water temperature is normal and the heating rate is normal, it is necessary to consider whether the radiator of the heater is blocked or the pipeline circulation is abnormal.

Extended data:

The use of Volkswagen Jetta heater is introduced as follows:

During normal operation, there is a slight temperature difference between the two water pipes, but it is not big. When the small water tank is blocked or the return water pipe is not circulating smoothly, the temperature difference between the two warm air pipes will increase. For example, the inlet pipe feels hot, the outlet pipe feels cold, and the temperature difference is much worse. In most cases, the internal blockage of small water tanks is related to unqualified coolant or long-term non-replacement.

You can try not to disassemble the machine to wash it, because it takes time and effort to change this small water tank. When the small water tank can't flush, you can consider replacing it. In another case, there is no temperature at the inlet and outlet of the small water tank, indicating that the coolant has not entered the small water tank. The first reason is air in the coolant circulation system.
