How a heater works on a Lancia Delta 2

In the middle of winter it is our best ally on the way when we go to work. When it does not work well we regret it intensely. In this situation to know where the problem is coming from, you will need to know how it works on your Lancia Delta 2, at least the basics. The heating uses the engine block temperature to raise the temperature of the personalised tour, then generally the cooling device. So there is duplication. Also, the emission device, so that the air reaches us also presents a duplication. It's the ventilateur which sends the air when the car is driving slowly or not at all, then it is the speed of the vehicle which allows the air to be sent when you drive faster. It's pretty clever isn't it?

Recurring heating problems on a Lancia Delta 2

Broken thermostat

The concept is elementary, if the thermostat which regulates the heat does not measure the temperature of the water circuit well, the whole circuit is affected. Even if the thermostat of your Lancia Delta 2 does not activate well, the heating will still work. Because the temperature coming from the engine block will gradually increase, so will the cooling circuit, even without a thermostat. Our only hassle is that you can't really change the heat emitted.

Air shutters blocked on Lancia Delta 2

This is a problem 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

You have now entered, the fan is useful only at reduced speed or the engine off. If this heater never generates more heat at reduced speed and you still hear noise, it means that your fan is probably screwed up. Ordinarily, with a higher speed, the heating of your Lancia Delta 2 will work. If the fan does not activate, it will have to be replaced.

Blocked hoses

Its symptoms will be relatively simple. If your heating blows and does not heat or little, the problem is certainly from the hoses. They become blocked the more time passes and do not allow hot water to access the heating of your Lancia Delta 2. In this situation, remove the hoses or install new ones.

Air pocket in the Lancia Delta 2 circuit

The symptom is sometimes identical to those of the hoses. If ever air bubbles have entered the heart of the circuit, water also has problems reaching the radiator of the heating of your Lancia Delta 2. In this situation, it is only necessary to purge the water circuit.

Conclusion

You now know where this problem will come from. However, the problem may come from another location, for example the air duct of your blocked Lancia Delta 2, or a defective valve, however it is still rather rare. Do not hesitate to leave a comment in case this tutorial helped you. Good walk !
