How a heater works on a Volkswagen Iltis
In the middle of winter it is our best ally on the road when we go to work. And when the latter does not activate, we miss it intensely. In this situation in order to find out where the problem comes from, we will have to understand how it works on this Volkswagen Iltis, or at least the main lines. The heating uses the engine temperature to increase the heat of the personalised tour, and generally the cooling device. Therefore it is a two in one. In addition, the emission device, so that the hot air reaches us has a double system. It's the ventilateur which emits hot air when the car is running at low speed or not at all, and it is the speed of the car which makes it possible to send hot air once you are traveling faster. Well designed, right?
Recurring heating problems on a Volkswagen Iltis
Broken thermostat
The concept is easy, when the thermostat which regulates the temperature does not really understand the degree of heat of the water circuit, the latter is affected. Even if the thermostat of this Volkswagen Iltis still does not work properly, the heating will still work. Quite simply because the temperature produced by the engine will increase progressively, and the water circuit in the same way, even without thermostat. The only hassle is that you can't really change the air temperature.
Air shutters blocked on the Volkswagen Iltis
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.
Faulty fan on the Volkswagen Iltis
As you might expect, the fan is useful only at low speed or the engine off. If it happens that your heating system does not emit any more heat at low speed and that nevertheless you discern nevertheless a sound, that means that this fan is probably defective. If all goes well, with more speed the heating of this Volkswagen Iltis should turn. In case the fan does not work at all it is better to replace it with a new one.
Blocked hoses
The symptoms will be relatively obvious. When your heating blows but does not create little or no heat, the problem probably comes from the hoses. These clog up over time and no longer allow hot water to reach the heating of this Volkswagen Iltis. In this situation, clean the hoses or put new ones.
Air pocket in the circuit of the Volkswagen Iltis
The symptom is sometimes the same as that of the hoses. If it happens that small pockets of air are encrusted inside the circuit, the high temperature water will also have problems accessing the heating radiator of your Volkswagen Iltis. In this situation, it will suffice to purge the water circuit.
Conclusion
You now know where your problem will arise. That said, it is possible that the reason comes from another place, for example the air duct of this obstructed Volkswagen Iltis, even a broken valve, but it is still less frequent. You can write a comment in case this text helped you. Good road !
