How a heater works on a Nissan Silvia

In the middle of winter it is our best ally on the way to work. When it does not work well we notice it intensely. In this situation to know where the problem comes from, you need to understand how it works on this Nissan Silvia, or at least the main lines. The heating uses the engine temperature to warm up the personalised tour, then in most cases of the cooling mechanism. In fact this system has several functions. Similarly, the fan mechanism, so that the hot air comes into the cabin also has a double use. There is a ventilateur which sends hot air when the car is traveling at low speed or not, then it is the speed of the vehicle which allows hot air to be sent when you are traveling at high speed. Well designed, right?

Recurring heating problems on a Nissan Silvia

Broken thermostat

The concept is elementary, in the case where the thermostat which regulates the heat does not understand well the temperature of the cooling circuit, the whole circuit is impacted. Even if the thermostat of this Nissan Silvia does not work properly, the heating will still work. Because the natural temperature of the engine will increase over time, and so will the water circuit, even without a thermostat. Our only annoyance is that you can't really change the temperature.

Air shutters blocked on the Nissan Silvia

It's a concern 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 Nissan Silvia

As you can imagine, the fan only works at low speed and the engine off. If this heater does not generate heat at low speed and yet you still hear noise, it means that the fan will probably fail. Ordinarily, with more speed, the heating of this Nissan Silvia should work. If the fan really does not work, it should be replaced.

Blocked hoses

The symptoms are relatively simple. When your heating blows and creates little or no heat, the problem probably comes from the hoses. These clog up the more time passes and do not allow hot water to access until the heating of this Nissan Silvia. Therefore, wash the hoses or replace them with new ones.

Air pocket in the circuit of the Nissan Silvia

The syndrome is sometimes identical to that of the hoses. If air bubbles have ever entered the circuit, the high temperature water has the same problems to access the radiator of the heating of the Nissan Silvia. From then on, it will suffice to purge the water circuit.

Conclusion

You now know where your concern may arise. That said it is possible that the reason comes from another part, for example the air duct of this clogged Nissan Silvia, or a defective valve, but it is still rather rare. Leave us a comment in case this article was useful to you. Good walk !
