How a heater works on a Toyota Prius 4
When it is cold, heating is essential on the road to go to work. And when the latter does not turn out well we regret it intensely. So in order to know where the problem is coming from, it is necessary to understand how it works on your Toyota Prius 4, at least the basics. The heating uses the engine temperature to be able to heat up the heat personalised tour, then very often the cooling mechanism. So it's a two in one. Similarly, the fan mechanism, so that the hot air arrives in the cabin has a double system. There is a ventilateur which emits hot air when the vehicle is driving slowly or not, then it is the speed of the vehicle which will send the hot air once you are driving faster. Well designed, right?
Recurring heating problems on a Toyota Prius 4
Broken thermostat
The idea is affordable, if the thermostat that regulates the heat does not really understand the degree of heat of the water circuit, the entire circuit is affected. Even if the thermostat of your Toyota Prius 4 still does not activate properly, the heating will still work. Because the temperature produced by the engine will gradually increase, and the cooling circuit in the same way, whether the thermostat works or not. Our only concern is that you will have trouble controlling the air temperature.
Air shutters blocked on the Toyota Prius 4
This is a problem 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.
Defective fan on the Toyota Prius 4
As you can imagine, the fan is only used at low speed and stopped. If this heater does not emit air at low speed and you still hear its noise, it's good that your fan turns out to be probably running. Normally, with high speed, the heating of your Toyota Prius 4 will work. Assuming that the fan does not activate at all it is better to change it.
Blocked hoses
His symptoms turn out to be relatively simple. In case your heating works but does not create little or no heat, the problem probably comes from the hoses. They clog up the more time passes and do not allow hot water to reach your heating of your Toyota Prius 4. In this case, clean the hoses or replace them with new ones.
Air pocket in the circuit of the Toyota Prius 4
The syndrome is found to be similar to that of the durits. In the event that air streams are inserted into the heart of the circuit, water has the same difficulty in reaching the radiator of the heating of this Toyota Prius 4. In this specific case, it suffices to purge the circuit.
Conclusion
You now understand where this problem may come from. By cons it happens that the problem comes from another place, such as the air duct of your Toyota Prius 4 obstructed, or a defective valve, however it is still quite rare. Leave us a comment in case this article helped you. Good walk !
