How a heater works on a Smart Fortwo 3

In the middle of winter, heating is our best ally on the road when we go to work. When it does not work well we regret it intensely. So in order to understand where the problem comes from, it is necessary to understand how it works on this Smart Fortwo 3, at least its principle. The heating use the engine block temperature to warm up the personalised tour, and very often the cooling mechanism. In fact this system has several functions. Also, the emission mechanism, so that the hot air arrives in the hbaitacle also has a duplication. There is a ventilateur which emits hot air as soon as the vehicle is moving slowly or is stationary, and it is the speed of your automobile that allows you to send hot air as soon as you drive faster. Pretty smart isn't it?

Recurring problems with heating on a Smart Fortwo 3

Broken thermostat

The idea is easy, in the event that the thermostat which regulates the temperature does not really measure the degree of heat of the cooling circuit, the whole of the latter is affected. Even if the thermostat of this Smart Fortwo 3 no longer activates properly, the heating will still work. Because the temperature coming from the engine block will increase over time, then the cooling circuit at the same time, whether it is regulated or not. Our only annoyance is that you will have trouble controlling the heat emitted.

Air flaps blocked on the Smart Fortwo 3

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 Smart Fortwo 3

As you can imagine, the fan is only used at low speed or in neutral. If ever the heater does not emit heat at low speed and you still hear its noise, it means that this fan is very likely to run out. If all goes well, with more speed the heating of this Smart Fortwo 3 should work. If the fan does not activate at all, it should be changed.

Blocked hoses

The signs are quite simple. When your heater blows but does not generate hot air or very little, the problem probably comes from the hoses. The more time passes, these become clogged and do not allow hot water to access the heating of this Smart Fortwo 3. In this situation, unclog the hoses or put new ones.

Air pocket in the circuit of the Smart Fortwo 3

The syndrome is sometimes similar to those of hoses. If ever air bubbles have become encrusted in the circuit, the high temperature water also has problems accessing the heater radiator of the Smart Fortwo 3. In this situation, all you have to do is purge the circuit. water.

Conclusion

You now understand where your problem is going to arise. On the other hand, it may be that the problem comes from another place, such as the air duct of this cluttered Smart Fortwo 3, or even a defective tap, but this is still rarer. Leave us a comment if this article has helped you. Good road !
