How a heater works on a Renault Fregate

In the middle of winter it is a definite asset on the journey to go to work. When it doesn't work well we miss it quickly. In this situation before knowing what the malfunction comes from, you need to understand how it works on this Renault Fregate, at least its principle. The heating uses the engine temperature to warm up the personalised tour, then generally the cooling system. In fact it is a two in one. Similarly, the fan system, so that the heat arrives in the cabin also has a double use. It's the ventilateur which emits heat when the vehicle is running at low speed or not, then it is the speed of the car which will send the heat as soon as you move faster. It's pretty clever isn't it?

Recurring heating problems on a Renault Fregate

Broken thermostat

The idea is simple, assuming that the thermostat which regulates the heat does not measure the temperature of the water in the circuit well, the latter is impacted. Even if the thermostat of this Renault Fregate does not activate properly, the heating will still work. Quite simply because the natural temperature of the engine will increase over time, then the water circuit in the same way, even without a thermostat. The only annoyance is that you can't really adjust the temperature.

Air shutters blocked on the Renault Fregate

It is a dysfunction 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 Fregate

As you might expect, the fan is useful only at low speed or when stopped. If the heating does not generate heat at low speed but you still hear a sound, it means that the fan is likely to have failed. A priori, thanks to more speed, the heating of this Renault Fregate will turn. If the fan does not activate at all, you will have to replace it with a new one.

Blocked hoses

Its symptoms are relatively obvious. If your heating turns and does not heat or very slightly, the malfunction probably comes from the hoses. They clog up over time and no longer allow hot water to reach your heating of this Renault Fregate. In this case, clean the hoses or replace them with new ones.

Air pocket in the Renault Fregate circuit

The syndrome is sometimes similar to that of the durits. In case air pockets are introduced inside the circuit, high temperature water also has trouble reaching the radiator of the Renault Fregate heater. In this case, it will suffice to purge the water circuit.

Conclusion

You now understand what will cause your dysfunction. Nevertheless it happens that the problem comes from another place, for example the air duct of this cluttered Renault Fregate, or a defective tap, but it is still less frequent. Leave us a comment if this text helped you. Enjoy the road!
