How a heater works on a Nissan Interstar Combi

In the middle of winter, heating is a definite asset on the trip when you go to work. When it does not activate well we miss it intensely. In this situation before understanding where the problem comes from, you will need to understand how it works on your Nissan Interstar Combi, or at least the main lines. The heating uses the heat from the engine to increase the heat of the personalised tour, and in most cases of the cooling mechanism. So this system has several functions. Also, the emission mechanism, for the heat to reach us presents a double system. It's the ventilateur which sends the heat as soon as the car is driving slowly or not, and it is the speed of your car which will send the heat when you are driving faster. Pretty well thought out right?

Recurring heating problems on a Nissan Interstar Combi

Broken thermostat

The idea is elementary, in the case where the thermostat which regulates the temperature does not understand well the temperature of the water in the circuit, the whole circuit is affected. Even if the thermostat on your Nissan Interstar Combi still does not work properly, the heating will still work. Quite simply because the heat produced by the engine will increase progressively, then the cooling circuit at the same time, whether the thermostat works or not. The only hassle is that you will have trouble regulating the heat emitted.

Air shutters blocked on the Nissan Interstar Combi

It is a concern 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.

Faulty fan on the Nissan Interstar Combi

As you can imagine, the fan is effective only at reduced speed and the engine off. If this heating system does not emit air at reduced speed but you still discern noise, it means that this fan will most likely be broken. If all goes well, with more speed the heating of your Nissan Interstar Combi will be able to work. If it happens that the fan does not work at all it is better to replace it.

Blocked hoses

The symptoms will be relatively simple. When your heating works and does not generate very little hot air, the problem probably comes from the hoses. These become blocked over time and do not allow hot water to access the heating of your Nissan Interstar Combi. So wash the hoses or replace them with new ones.

Air pocket in the circuit of the Nissan Interstar Combi

The syndrome is sometimes similar to that of the durits. If air pockets are introduced inside the circuit, the water will also have problems accessing the heating radiator of this famous Nissan Interstar Combi. Then, it will be enough to purge the circuit.

Conclusion

You now understand where your concern might come from. By cons it happens that the problem comes from elsewhere, such as the air duct of your Nissan Interstar Combi obstructed, or a defective valve, but it is still more rare. Leave us a comment in case this post was useful to you. Good walk !
