How a heater works on a Volkswagen 181

When it is cold it is essential on the road to go to work. And when it does not activate it is easily missed. In this case, before you know what the problem is, you need to understand how it works on your Volkswagen 181, at least the basics. The heating uses the engine block temperature to warm the personalised tour, then in most cases the cooling system. In fact this system has several functions. Similarly, the emission system, so that the air arrives in the cabin also has a double use. There is a ventilateur which sends the air when the car is driving slowly or is stopped, then it is the speed of the car which will send the air once you are driving faster. Well designed, right?

Recurring heating problems on a Volkswagen 181

Broken thermostat

The notion is elementary, in the case where the thermostat which regulates the temperature does not really measure the degree of heat of the water in the circuit, the latter is impacted. Even if the thermostat of your Volkswagen 181 still does not activate well, the heating will still work. Because the temperature produced by the engine block will increase over time, so the cooling circuit in the same way, whether the thermostat works or not. The only concern is that you can't really change the temperature.

Air shutters blocked on the Volkswagen 181

This is a problem that occurs quite frequently. 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 181

You have now entered, the fan is useful only at reduced speed or in neutral. In case the heating system does not emit too much heat at reduced speed and yet you still hear its noise, it is good that your fan will certainly be defective. In principle, thanks to the high speed, the heating of your Volkswagen 181 will work. If it happens that the fan does not activate at all it is better to change it.

Blocked hoses

His clues are relatively simple. In the event that your heating works and does not create little or no heat, the problem certainly comes from the hoses. They become blocked over time and do not allow hot water to reach the heating of your Volkswagen 181. In this case, clog the hoses or replace them with new ones.

Air pocket in the circuit of the Volkswagen 181

The syndrome will be similar to those of the durits. If air streams are inserted in the circuit, the high temperature water will have the same problems to reach the radiator of the heating of this famous Volkswagen 181. In this specific case, it is necessary to purge the circuit.

Conclusion

You now know what will cause your problem. However it is possible that the problem comes from another place, like the air duct of your cluttered Volkswagen 181, or a broken tap, however it is still rather rare. You can write a comment if ever this post served you. Enjoy the road!
