How a heater works on a Smart Crosstown

When it is cold, heating is a definite asset on the journey when you go to work. And when the latter does not turn well we notice it quickly. In this situation in order to understand where the malfunction comes from, you will have to understand how it works on your Smart Crosstown, at least in a simplified way. The heating uses engine temperature to raise the temperature of the personalised tour, and in most cases of the cooling mechanism. In fact this system has several functions. Similarly, the emission mechanism for heat to reach us presents a double system. There is a ventilateur which sends the heat as soon as the car is running at low speed or not, and it is the speed of the car which will send the heat once you drive faster. It's pretty clever isn't it?

Recurring heating problems on a Smart Crosstown

Broken thermostat

The concept is elementary, in the case where the thermostat which regulates the temperature does not really understand the temperature of the water circuit, the whole of the latter is affected. Even if your Smart Crosstown's thermostat no longer works well, the heating will operate normally. Because the natural temperature of the engine will increase gradually, then the cooling system in the same way, even without a thermostat. The only concern is that you can't really adjust the temperature.

Air shutters blocked on Smart Crosstown

It is a dysfunction that happens 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.

Faulty fan on Smart Crosstown

As you will have understood, the fan is effective only at low speed or the engine off. If the heater no longer emits air at low speed and you still hear noise, it means that the fan turns out to be probably screwed up. A priori, thanks to more speed the heating of your Smart Crosstown must work. Assuming the fan is really not spinning it is better to replace it.

Blocked hoses

The clues are relatively obvious. In the event that your heating blows but does not create heat or very little, the malfunction is probably due to the hoses. These become blocked as time goes by and no longer allow hot water to access the heating of your Smart Crosstown. In this specific case, clean the hoses or install new ones.

Air pocket in the Smart Crosstown circuit

The syndrome happens to be identical to that of the hoses. In the event that air bubbles are inserted inside the circuit, high temperature water will similarly have problems reaching the heating radiator of your Smart Crosstown. In this case, it is necessary to purge the circuit.

Conclusion

You now understand where this malfunction may come from. However, it is possible that the problem came from another place, such as the air duct of your cluttered Smart Crosstown, or even a defective tap, but it is unfortunately more rare.
