How a heater works on a Volkswagen 411

In winter the heating is a definite asset on the road when you go to work. And when it doesn't work well we miss it dearly. So before understanding what the problem is, it is necessary to know how it works on the famous Volkswagen 411, at least the basics. The heating uses the temperature of the engine block to increase the heat of the personalised tour, and in most cases the cooling mechanism. So it's a two in one. In a similar way, the fan mechanism, for the hot air to come into the cabin, also has a duplication. There is a ventilateur which emits hot air as soon as the automobile is turned at low speed or at walking pace, and it is the speed of the vehicle that will send the hot air when you are traveling at high speed. Pretty smart isn't it?

Recurring heating problems on a Volkswagen 411

Broken thermostat

The concept is simple, if the thermostat which regulates the heat does not really understand the temperature of the cooling circuit, the entire circuit is affected. Even if the thermostat of the famous Volkswagen 411 is still not working well, the heating will still work. Because the natural temperature of the engine block will gradually increase, and so will the water circuit, even without a thermostat. The only concern remains that you will not be able to really control the heat emitted.

Air shutters blocked on the Volkswagen 411

This is a problem that happens quite often. These shutters, which allow you to direct the air or adjust the intensity, sometimes get blocked over time. To remedy this it is simple, remove the cover and look inside how it was done. Activate the mechanisms to see where it is blocking. Put a little WD 40 to lubricate and voila.

Defective fan on the Volkswagen 411

As you will understand, the fan is useful only at low speed or when stopped. In the event that this heating system does not send out heat at low speed and you still hear a sound, it is good that your fan is probably on. Normally, thanks to a brisk pace, the heating of the famous Volkswagen 411 should work. If ever the fan does not really work, it will have to be replaced by a new one.

Blocked hoses

The symptoms will be relatively simple. When your heater works but does not generate hot air or little, the problem is certainly with the hoses. They become clogged over time and no longer allow hot water to reach the heating of the famous Volkswagen 411. In this case, wash the hoses or put new ones.

Air pocket in the circuit of the Volkswagen 411

The symptom is sometimes similar to those of the hoses. In the event that air streams have entered the circuit, high temperature water will also have difficulty reaching the heater radiator of this Volkswagen 411. In this case, it is only necessary to bleed the circuit d 'water.

Conclusion

Now you know where this problem will come from. However, it happens that the reason comes from another place, such as the air duct of the famous Volkswagen 411 blocked, or a faulty valve, but it is unfortunately rather rare. You can write a comment if this text helped you. Enjoy the road!
