How a heater works on a Renault Kangoo Rx-4
In the middle of winter, heating is our best ally on the road to go to work. And when it doesn't work, we very much regret it. So to know where the malfunction comes from, it is essential to know how it works on this Renault Kangoo Rx-4, at least in a simplified way. The heating use the temperature of the engine block so as to raise the temperature of the personalised tour, and in most cases of the cooling mechanism. Consequently, this duplicates. In a similar way, the emission mechanism, so that heat comes into the interior also presents a double use. It's the ventilateur which emits heat when the car is running at low speed or not at all, and it is the speed of your car that will send the heat once you are driving faster. It's pretty clever isn't it?
Recurring heating problems on a Renault Kangoo Rx-4
Broken thermostat
The concept is easy, assuming that the thermostat which regulates the heat does not really capture the degree of heat of the cooling circuit, the whole of the latter is affected. Even if the thermostat of this Renault Kangoo Rx-4 does not work properly, the heating will still work. Because the temperature produced by the engine block will increase over time, so the cooling circuit at the same time, whether it is regulated or not. Our only hassle is that you will have trouble changing the temperature.
Air shutters blocked on the Renault Kangoo Rx-4
It is a dysfunction 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 Renault Kangoo Rx-4
As you can imagine, the fan is only used at low speed and the engine off. If the heater never emits more air at low speed and yet you can still hear noise, it's good that this fan is most likely defective. Normally, with more speed, the heating of this Renault Kangoo Rx-4 will be able to turn. If the fan does not work, it is better to replace it.
Blocked hoses
Its clues will be rather obvious. When your heating blows and does not heat or very slightly, the malfunction is probably due to the hoses. They become blocked over time and no longer allow hot water to heat this Renault Kangoo Rx-4. In this case, unclog the hoses or put new ones.
Air pocket in the circuit of the Renault Kangoo Rx-4
The syndrome will be identical to that of the durits. If ever air bubbles are inserted within the circuit, the water will also have problems reaching the radiator of the heating of your Renault Kangoo Rx-4. In this case, it will suffice to purge the circuit.
Conclusion
You now understand where this dysfunction can occur. However it may be that the problem comes on the other hand, like the air duct of this clogged Renault Kangoo Rx-4, or a defective valve, but it is still rarer. Leave us a comment in case this tutorial has served you. Good walk !
