How a heater works on a smart roadster

When it's cold it's essential on the way when you go to work. And when the latter no longer works it is easily missed. In this case in order to know what the problem comes from, you will need to know how it works on this smart roadster, at least in a simplified way. The heating uses engine temperature to raise the temperature of the personalised tour, then very often from the cooling system. So this system has several functions. Similarly, the ventilator system, so that the air comes into the cabin also presents a duplication. It's the ventilateur which sends the air when the car is moving slowly or is stopped, then it is the speed of the vehicle which will send the air as soon as you drive at high speed. It's pretty clever isn't it?

Recurring heating problems on a smart roadster

Broken thermostat

The concept is simple, when the thermostat that regulates the heat does not properly understand the degree of heat of the water circuit, the entire circuit is affected. Even if the thermostat of this smart roadster no longer turns correctly, the heating will work normally. Quite simply because the temperature produced by the engine will increase progressively, then the cooling circuit at the same time, even without a thermostat. The only annoyance is that you will hardly be able to modify the heat emitted.

Air flaps blocked on the smart roadster

It is a concern that happens quite regularly. 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 smart roadster

As you can imagine, the fan is effective only at low speed or in neutral. If your heater does not emit heat at low speed but you still hear noise, it's good that your fan is probably screwed up. As a general rule, with a high speed the heating of this smart roadster should turn. If the fan does not rotate at all it is better to change it.

Blocked hoses

His clues turn out to be relatively obvious. If your heating turns and does not create heat or very slightly, the problem is certainly caused by the hoses. These become blocked over time and no longer allow hot water to access your heating of this smart roadster. In this specific case, wash the hoses or install new ones.

Air pocket in the smart roadster circuit

The syndrome is sometimes the same as that of the hose lines. In the event that air streams are embedded in the heart of the circuit, the water will similarly have problems arriving at the heating radiator of this famous smart roadster. In this specific case, it will suffice to purge the water circuit.

Conclusion

You now know what the problem may come from. However it happens that the reason comes from elsewhere, like the air duct of this obstructed smart roadster, even a defective tap, however it is still more rare. Leave us a comment if you have ever used this tutorial. Enjoy the road!
