How a heater works on a Nissan Interstar

In the middle of winter it is essential on the way when you go to work. And when the latter no longer rotates we regret it intensely. In this situation before understanding where the malfunction came from, you will need to know how it works on this Nissan Interstar, at least the basics. The heating uses engine temperature to heat the personalised tour, and generally the cooling system. In fact this system has several functions. Also, the emission system, so that the air arrives in the cabin has a double system. There is a ventilateur which emits air when the vehicle is running at low speed or not, and it is the speed of the vehicle which will send the air as soon as you drive faster. Well designed, right?

Recurring heating problems on a Nissan Interstar

Broken thermostat

The concept is simple, in the case where the thermostat which regulates the heat does not really capture the degree of heat of the water circuit, the entire circuit is affected. Even if the thermostat of this Nissan Interstar does not turn properly, the heating will still work. Quite simply because the temperature produced by the engine will increase over time, and the cooling system too, whether it is regulated or not. The only annoyance is that you will have trouble regulating the heat emitted.

Air shutters blocked on the Nissan Interstar

It is a dysfunction that happens 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

As you can imagine, the fan is effective only at low speed and in neutral. If this heater does not emit too much air at low speed and nevertheless you still discern noise, it means that your fan turns out to be probably running out. If all goes well, with a high speed the heating of this Nissan Interstar will work. If the fan does not turn at all, it must be replaced.

Blocked hoses

The symptoms will be fairly simple. When your heating works and does not create heat or very slightly, the malfunction probably comes from the hoses. They get dirty over time and no longer allow hot water to access the heating of this Nissan Interstar. In this case, wash the hoses or replace them with new ones.

Air pocket in the circuit of the Nissan Interstar

The syndrome is the same as that of the hose lines. If ever small pockets of air are introduced into the circuit, the water will have the same problems to access the radiator of the heating of the Nissan Interstar. In this case, it is necessary to purge the circuit.

Conclusion

You now understand where the malfunction will come from. However, it can happen that the problem comes on the other hand, for example the air duct of this cluttered Nissan Interstar, or a broken tap, but it is still rarer.
