How a heater works on a Toyota Prius 4 Rechargeable

When it is cold it is a definite asset on the way to work. And when the latter does not work well he is dearly missed. In this situation before knowing where the malfunction comes from, we will have to assimilate how it works on the famous Toyota Prius 4 Rechargeable, or at least the outline. The heating uses heat from the engine block to heat the personalised tour, then in most cases the cooling device. In fact this system has several functions. In a similar way, the fan device, for the air to come into the cabin, also has a duplication. It's the ventilateur which emits the air when the car is rolling smoothly or or not at all, then it is the speed of the vehicle which will send the air once you drive faster. Well designed, right?

Recurring heating problems on a Toyota Prius 4 Rechargeable

Broken thermostat

The notion is easy, in the event that the thermostat which makes it possible to adjust the temperature does not really measure the temperature of the cooling circuit, the latter is affected. Even if the thermostat of the famous Toyota Prius 4 Rechargeable still does not work correctly, the heating will still work. Because the natural heat of the engine block will gradually increase, and so will the water circuit, whether the thermostat is working or not. The only inconvenience remains that you will not be able to really modify the heat emitted.

Air shutters blocked on the Toyota Prius 4 Rechargeable

It is a dysfunction that happens quite 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.

Defective fan on the Toyota Prius 4 Rechargeable

You have now entered, the fan is only used at low speed and when stopped. If your heating system isn't emitting too much heat at low speed, and you still hear noise, then this fan is most likely going to run out. In principle, with a higher speed, the heating of the famous Toyota Prius 4 Rechargeable should work. If the fan does not work at all, it will have to be replaced by a new one.

Blocked hoses

The clues turn out to be rather obvious. If your heater blows but does not heat up or very slightly, the malfunction must probably come from the hoses. They get clogged over time and do not allow hot water to reach your heater of the famous Toyota Prius 4 Rechargeable. In this case, clean the hoses or replace them with new ones.

Air pocket in the circuit of the Toyota Prius 4 Rechargeable

The symptom is sometimes the same as that of the hoses. If air streams are embedded in the circuit, the high temperature water similarly has problems reaching the heater radiator of this famous Toyota Prius 4 Rechargeable. In this case, all you need to do is purge the circuit.

Conclusion

You now understand where this dysfunction will come from. On the other hand, it is possible that the reason comes from elsewhere, like the air duct of the famous Toyota Prius 4 Rechargeable plugged, or a defective valve, but it is all the same rather rare.
