How does a heater work on a Renault Kangoo 2 Express

In winter it is essential on the journey when going to work. And when the latter does not work, it is quickly noticed. So before knowing where the problem comes from, we must understand how it works on the famous Renault Kangoo 2 Express, at least in a simplified way. The heating use the temperature of the engine block to raise the temperature of the personalised tour, and generally of the cooling system. In fact this is duplicative. In a similar way, the emission system, so that the hot air reaches us also has a duplication. It's the ventilateur which emits hot air as soon as the vehicle is moving slowly or is stationary, and it is the speed of the vehicle that will send the hot air when you are moving faster. Well designed, right?

Recurring problems with heating on a Renault Kangoo 2 Express

Broken thermostat

The concept is elementary, supposing that the thermostat which regulates the heat does not really measure the degree of heat of the water circuit, the whole circuit is affected. Even though the thermostat of the famous Renault Kangoo 2 Express still does not work well, the heating will still work. Because the temperature coming from the engine block will increase little by little, then the cooling circuit in the same way, even without a thermostat. The only problem remains that you will have trouble setting the heat emitted.

Air flaps blocked on the Renault Kangoo 2 Express

This is a problem that occurs 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.

Defective fan on the Renault Kangoo 2 Express

As you can imagine, the fan is effective only at low speed and at a standstill. If it happens that this heating system no longer generates air at low speed and yet you still hear a sound, it means that the fan is probably defective. As a general rule, with more speed the heating of the famous Renault Kangoo 2 Express should work. If the fan does not work, it will have to be changed.

Blocked hoses

The symptoms turn out to be relatively simple. When your heater turns on but does not heat or only slightly, the problem is probably with the hoses. The latter get dirty over time and no longer leave the possibility for hot water to reach your heating of the famous Renault Kangoo 2 Express. So clean the hoses or replace them with new ones.

Air pocket in the Renault Kangoo 2 Express circuit

The symptom is found to be the same as those of the hoses. If it happens that air pockets are stored inside the circuit, the water will also have problems reaching the heating radiator of the Renault Kangoo 2 Express. So, all you have to do is purge the water circuit.

Conclusion

You now know where the problem is going to arise. However, it may be that the problem comes from another place, such as the air duct of the famous Renault Kangoo 2 Express blocked, or a faulty valve, however it is still rather rare.
