How a heater works on a Renault Grand Kangoo

In the middle of winter, heating is our best ally on the way when we go to work. And when it no longer works we easily regret it. So before finding out where the problem comes from, it is necessary to know how it works on your Renault Grand Kangoo, at least in a simplified way. The heating uses the engine block temperature to warm the personalised tour, then in most cases the cooling system. So it's a two in one. Also, the emission system, so that the hot air reaches the cabin has a double system. It's the ventilateur which sends hot air when the vehicle is traveling at low speed or is stopped, then it is the vehicle speed which allows hot air to be sent when you are driving at high speed. Pretty well thought out right?

Recurring heating problems on a Renault Grand Kangoo

Broken thermostat

The concept is elementary, in the case where the thermostat which regulates the temperature does not measure well the degree of heat of the cooling circuit, the whole circuit is affected. Even if the thermostat of your Renault Grand Kangoo still does not work correctly, the heating will work normally. Simply because the temperature coming from the engine block will gradually increase, then the water circuit at the same time, whether the thermostat works or not. Our only hassle is that you will hardly be able to adjust the air temperature.

Air flaps blocked on the Renault Grand Kangoo

This is a problem that occurs fairly 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 Renault Grand Kangoo

As you might expect, the fan is useful only at low speed or in neutral. If your heating does not generate any more air at reduced speed and that nevertheless you still discern a sound, it is good that the fan is certainly defective. If all goes well, with a high speed the heating of your Renault Grand Kangoo will be able to work. If the fan does not work it is better to replace it.

Blocked hoses

The clues will be relatively obvious. If your heating works but does not generate hot air or very slightly, the problem is certainly due to the hoses. These become blocked over time and no longer allow hot water to access until the heating of your Renault Grand Kangoo. In this case, remove dirt from the hoses or replace them with new ones.

Air pocket in the circuit of the Renault Grand Kangoo

The syndrome is sometimes the same as that of the hose lines. If air streams have become embedded in the heart of the circuit, water also has problems reaching the radiator of the heating of your Renault Grand Kangoo. In this case, it is necessary to purge the circuit.

Conclusion

You now understand where this problem can occur. However it sometimes happens that the problem originates on the other hand, like the air duct of your clogged Renault Grand Kangoo, or a defective tap, however it is nevertheless less frequent.
