How a heater works on a Lancia Delta 2 Hf
When it is cold it is a definite asset on the journey when you go to work. When it does not activate it is sorely missed. Therefore, before knowing where the problem comes from, you will have to understand how it works on your Lancia Delta 2 Hf, or at least the main lines. The heating uses the heat from the engine block to heat the personalised tour, and in most cases the cooling system. So there is duplication. Also, the fan system, so that the hot air comes to us presents a double system. There is a ventilateur which sends hot air when the car is running at low speed or is stopped, and it is the speed of your car which will send hot air once you drive faster. Well designed, right?
Recurring heating problems on a Lancia Delta 2 Hf
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 cooling circuit, the whole circuit is affected. Even if the thermostat of your Lancia Delta 2 Hf no longer works properly, the heating will still work. Because the heat from the engine block will gradually increase, then the water circuit at the same time, even without a thermostat. Our only inconvenience is that you will have difficulty controlling the temperature.
Air shutters blocked on Lancia Delta 2 Hf
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 Lancia Delta 2 Hf
As you will have understood, the fan is only used at low speed or when stopped. If your heating system no longer emits heat at low speed and nevertheless you still hear noise, it is good that the fan turns out to be probably screwed up. Normally, with a higher speed the heating of your Lancia Delta 2 Hf will turn. In case the fan does not rotate at all it will have to be changed.
Blocked hoses
The symptoms turn out to be quite simple. If your heating blows and does not generate little or no hot air, the problem probably comes from the hoses. These become blocked as time goes by and no longer allow hot water to reach your heating of your Lancia Delta 2 Hf. In this situation, wash the hoses or replace them with new ones.
Air pocket in the Lancia Delta 2 Hf circuit
The symptom will be similar to those of the hoses. If air bubbles are embedded in the heart of the circuit, hot water will also have problems reaching the radiator of your Lancia Delta 2 Hf. In this situation, all you have to do is purge the circuit.
Conclusion
You now understand from where the concern may arise. However, the reason may come from another place, such as the air duct of your cluttered Lancia Delta 2 Hf, or a broken tap, but this is unfortunately less frequent. Leave us a comment if this post served you well. See you soon !
