How a heater works on a Seat 850
When it is cold, heating is a definite asset on the road when you go to work. And when the latter does not work well we notice it intensely. In this case to know where the problem is coming from, it is essential to understand how it works on your Seat 850, at least its principle. The heating uses the engine temperature to heat the personalised tour, then generally the cooling mechanism. Therefore it is a two in one. In addition, the fan mechanism, so that the hot air comes into the cabin also has a double use. It's the ventilateur which emits hot air when the car is traveling at low speed or is stopped, then it is the speed of your car which allows hot air to be sent when you circulate faster. Pretty well thought out right?
Recurring heating problems on a Seat 850
Broken thermostat
The concept is affordable, when the thermostat that regulates the heat does not really capture the degree of heat of the water circuit, the whole of the latter is affected. Even if the thermostat of your Seat 850 does not turn well, the heating will work normally. Quite simply because the temperature coming from the engine will gradually increase, and the water circuit too, even without a thermostat. The only annoyance is that you will have trouble controlling the air temperature.
Air shutters blocked on the Seat 850
This is a problem 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 the Seat 850
As you will have understood, the fan is only used at low speed or when stopped. If the heating system no longer generates heat at low speed and you still hear a sound, it means that your fan turns out to be probably defective. Normally, at a higher speed the heating of your Seat 850 should turn. If it happens that the fan really does not rotate it will have to be changed.
Blocked hoses
The signs turn out to be quite simple. In the event that your heating works but does not heat or very slightly, the problem probably comes from the hoses. They become dirty over time and do not allow hot water to reach your heating system in your Seat 850. In this situation, wash the hoses or install new ones.
Air pocket in the Seat 850 circuit
The syndrome is sometimes the same as that of the hose lines. In case air pockets are inserted in the circuit, the water has the same way of problems to reach the radiator of the heating of this famous Seat 850. In this situation, it will be enough for you to purge the circuit.
Conclusion
You now understand where your problem will arise. However it is possible that the reason came from another part, like the air duct of your cluttered Seat 850, or a faulty tap, however it is nevertheless less frequent. Do not hesitate to leave a comment in case this post served you. See you soon !
