How a heater works on a Volkswagen Golf 7

When it is cold it is our best ally on the way to work. And when the latter does not work we easily regret it. Therefore to find out where the malfunction comes from, it is necessary to know how it works on the famous Volkswagen Golf 7, or at least the main lines. The heating uses engine heat to warm the personalised tour, then generally the cooling system. In fact it is a two in one. Similarly, the fan system, so that the air arrives in the cabin has a double system. There is a ventilateur which sends air when the automobile is running at low speed or is stopped, then it is the speed of the vehicle which will send air when you are traveling at high speed. It's pretty clever isn't it?

Recurring heating problems on a Volkswagen Golf 7

Broken thermostat

The concept is simple, in the case where the thermostat which regulates the temperature does not correctly capture the temperature of the cooling circuit, the latter is affected. Even if the thermostat of the famous Volkswagen Golf 7 no longer works properly, the heating will still work. Because the heat coming from 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 set the air temperature.

Air shutters blocked on the Volkswagen Golf 7

It is a dysfunction that happens 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.

Defective fan on the Volkswagen Golf 7

You have now entered, the fan is only used at low speed or in neutral. If the heater does not emit too much heat at low speed and yet you still hear its noise, it is good that the fan will probably be defective. If all goes well, with a higher speed the heating of the famous Volkswagen Golf 7 will turn. Assuming that the fan does not rotate it is better to replace it with a new one.

Blocked hoses

The clues are pretty simple. When your heating blows and creates little or no heat, the malfunction probably comes from the hoses. These clog up over time and do not allow hot water to access the heating of the famous Volkswagen Golf 7. In this case, remove the hoses or replace them with new ones.

Air pocket in the circuit of the Volkswagen Golf 7

The syndrome will be similar to that of the durits. If ever air streams are introduced into the circuit, the water at high temperature will similarly have problems reaching the radiator of the Volkswagen Golf 7 heater. In this case, you just need to purge the circuit.

Conclusion

You now understand where your dysfunction will come from. However it happens that the reason is from the other hand, like the air duct of the famous Volkswagen Golf 7 obstructed, or a defective valve, but it is still more rare.
