How does a heater work on a Suzuki Sx4
In winter, heating is essential on the road to go to work. When it does not work well we regret it intensely. Therefore to understand where the malfunction came from, you will have to assimilate how it works on this Suzuki Sx4, at least in a simplified way. The heating uses the heat from the engine block to heat the personalised tour, and generally of the cooling system. Therefore this system has several functions. In addition, the fan system, so that the heat reaches us also presents a duplication. It's the ventilateur which emits heat when the automobile is driven at low speed or or not at all, and it is the speed of your automobile which will send the heat as soon as you go faster. Well designed, right?
Recurring problems with a heater on a Suzuki Sx4
Broken thermostat
The notion is easy, assuming that the thermostat which regulates the temperature does not really capture the temperature of the water in the circuit, the whole of the latter is affected. Even if the thermostat of this Suzuki Sx4 no longer works well, the heating will still work. Because the heat coming from the engine block will gradually increase, so the water circuit in the same way, whether it is regulated or not. Our only concern is that you will not be able to really control the heat emitted.
Air flaps blocked on the Suzuki Sx4
It is a dysfunction 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 Suzuki Sx4
As you will understand, the fan is only used at low speed and the engine is off. If ever this heating system is not sending too much heat at low speed but you can still hear its noise, it means the fan is probably going to be running. If all goes well, with a higher speed the heating of this Suzuki Sx4 will be able to work. If the fan does not work at all, it will have to be replaced by a new one.
Blocked hoses
Its clues will be relatively obvious. When your heater turns on but does not create heat or very little, the malfunction must probably come from the hoses. The latter clog up over time and no longer leave the possibility for hot water to reach the heating of this Suzuki Sx4. In this case, wash the hoses or replace them with new ones.
Air pocket in the circuit of the Suzuki Sx4
The symptom will be the same as for the hoses. If ever air bubbles have entered the circuit, high temperature water similarly has problems reaching the heater radiator of this Suzuki Sx4. In this case, it is necessary to purge the circuit.
Conclusion
You now understand where your dysfunction can be born from. However, it is possible that the problem comes from elsewhere, for example the air duct of this Suzuki Sx4 cluttered, or a defective valve, however it is still less frequent.
