How a heater works on a Renault Grand Espace 3
When it is cold, heating is essential on the way when going to work. And when the latter does not activate we quickly regret it. Therefore to find out what the problem is with, it is necessary to understand how it works on your Renault Grand Espace 3, at least its principle. The heating uses the engine temperature to heat up the heat personalised tour, and in most cases of the cooling mechanism. In this way this system has several functions. Also, the emission mechanism, so that the hot air comes to us has a double system. It's the ventilateur which emits hot air as soon as the car is traveling at low speed or is stopped, and it is the speed of the vehicle which will send hot air when you are traveling faster. Pretty well thought out right?
Recurring heating problems on a Renault Grand Espace 3
Broken thermostat
The concept is elementary, in the case where the thermostat which regulates the heat does not really understand the degree of heat of the water in the circuit, the whole of the latter is affected. Even if the thermostat of your Renault Grand Espace 3 does not work well, the heating will work normally. Quite simply because the natural temperature of the engine will increase over time, and the water circuit at the same time, whether the thermostat works or not. The only concern is that you will hardly be able to modify the heat emitted.
Air flaps blocked on the Renault Grand Espace 3
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 the Renault Grand Espace 3
As you can imagine, the fan only works at low speed and the engine off. If your heater does not generate heat at low speed and you still hear its noise, it means that your fan is probably screwed up. Normally, with a higher speed, the heating of your Renault Grand Espace 3 should work. If the fan really does not work it will have to be changed.
Blocked hoses
The clues turn out to be relatively obvious. When your heating works and does not create heat or very little, the concern must certainly come from the hoses. These become blocked over time and no longer allow hot water to access the heating of your Renault Grand Espace 3. Therefore, remove the hoses or replace them with new ones.
Air pocket in the circuit of the Renault Grand Espace 3
The syndrome is the same as that of the hose lines. If ever air pockets are stored in the heart of the circuit, high temperature water also has problems reaching the radiator of the heating of this famous Renault Grand Espace 3. From then on, you just have to purge the circuit of 'water.
Conclusion
You now know what will cause your concern. That said, it is possible that the problem comes from elsewhere, such as the air duct of your Renault Grand Espace 3 blocked, or even a defective valve, however it is still more rare. Leave us a comment in case this text helped you. Good road !
