How a heater works on a smart forfour
When it's cold it's a definite asset on the trip when you go to work. When it does not rotate we notice it intensely. In this situation to find out where the problem comes from, we will have to assimilate how it works on this smart forfour, at least the basics. The heating uses engine temperature to increase heat personalised tour, then generally the cooling system. In this way this system has several functions. Similarly, the fan system, so that the heat comes to us has a dual system. It's the ventilateur which emits heat as soon as the automobile is traveling at low speed or not, then it is the speed of the car which will send heat when you are driving faster. Pretty well thought out right?
Recurring heating problems on a smart forfour
Broken thermostat
The idea is elementary, if the thermostat which regulates the temperature does not really capture the degree of heat of the water in the circuit, the whole circuit is affected. Even if the thermostat of this smart forfour does not activate well, the heating will still work. Because the temperature coming from the engine will increase progressively, thus the cooling circuit at the same time, whether it is regulated or not. The only hassle is that you can hardly set the air temperature.
Air shutters blocked on the smart forfour
It's a concern 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 smart forfour
You have now entered, the fan operates only at low speed or the motor stopped. If your heating system does not send too much heat at low speed and nevertheless you can still hear a sound, then the fan will most likely be running. A priori, thanks to a fast pace the heating of this smart forfour should work. If the fan does not activate, you will have to replace it with a new one.
Blocked hoses
Its signs will be relatively obvious. If your heating blows and does not create heat or very little, the problem certainly comes from the hoses. They get dirty over time and no longer allow hot water to reach your heating in this smart forfour. Therefore, wash the hoses or replace them with new ones.
Air pocket in the smart forfour circuit
The symptom will be identical to that of the hoses. If air bubbles have entered the heart of the circuit, high temperature water has the same problems to reach the heating radiator of this smart forfour. Therefore, it is only necessary to purge the circuit.
Conclusion
You now know where the problem may arise. That said it may be that the problem comes from elsewhere, for example the air duct of this cluttered smart forfour, or a broken tap, but it is still less frequent. You can write a comment if this post has helped you. See you soon !
