How does a heating system work on a Renault Espace 3
Winter is our best ally on the road when we go to work. When it does not work we quickly regret it. In this situation before you know where the problem came from, you will need to understand how it works on your Renault Espace 3, at least the basics. The heating uses the temperature of the engine block to increase the heat of the personalised tour, then generally the cooling device. In this way it duplicates. Also, the fan device, so that the hot air comes into the cabin has a double system. It's the ventilateur which emits hot air as soon as the vehicle is running at low speed or not at all, then it is the speed of the car which will send hot air when you drive faster. Well designed, right?
Recurring heating problems on a Renault Espace 3
Broken thermostat
The concept is elementary, when the thermostat which regulates the temperature does not really measure the temperature of the cooling circuit, the latter is impacted. Even if the thermostat of your Renault Espace 3 still does not turn properly, the heating will still work. Quite simply because the temperature produced by the engine block will increase progressively, then the cooling circuit at the same time, even without a thermostat. The only annoyance is that you will have trouble controlling the heat emitted.
Air flaps blocked on the Renault Espace 3
This is a problem that occurs fairly regularly. 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 Renault Espace 3
As you will have understood, the fan is useful only at reduced speed or in neutral. If this heating does not generate heat at reduced speed but you still hear its noise, it means that the fan is probably running. Normally, thanks to the high speed, the heating of your Renault Espace 3 will be able to work. If the fan never turns in any way, it is better to replace it.
Blocked hoses
Its signs will be rather simple. When your heating turns and does not generate hot air or very slightly, the problem is certainly due to the hoses. These become blocked over time and no longer allow hot water to reach your heating of your Renault Espace 3. So, remove the hoses or put new ones.
Air pocket in the circuit of the Renault Espace 3
The syndrome will be the same as that of the hoses. If ever small pockets of air are introduced within the circuit, the water will also have problems to access the radiator of the heating of this Renault Espace 3. Then, it is enough to purge the circuit.
Conclusion
You now know where the problem may arise. On the other hand it is possible that the reason comes from elsewhere, such as the air duct of your Renault Espace 3 obstructed, or a deficient tap, but it is still less frequent. Leave us a comment if this post was useful to you. See you soon !
