How a heater works on a Toyota Yaris
In the middle of winter it is our best ally on the road when we go to work. And when the latter does not turn it is easily missed. In this case to find out where the malfunction came from, you will need to know how it works on this Toyota Yaris, at least in a simplified way. The heating uses heat from the engine block to increase heat from the personalised tour, then very often the cooling mechanism. Therefore this system has several functions. In addition, the emission mechanism, so that the hot air arrives in the cabin has a double system. There is a ventilateur which sends hot air as soon as the car is running at low speed or is stopped, then it is the speed of the vehicle which allows hot air to be sent when you are driving faster. It's pretty clever isn't it?
Recurring heating problems on a Toyota Yaris
Broken thermostat
The idea is elementary, in the case where the thermostat which makes it possible to regulate the temperature does not really understand the temperature of the cooling circuit, the whole of the latter is impacted. Even if the thermostat of this Toyota Yaris does not activate well, the heating will still work. Because the natural heat of the engine block will increase over time, so will the cooling system in the same way, whether it is regulated or not. The only hassle is that you will hardly be able to set the heat output.
Air shutters blocked on the Toyota Yaris
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 Toyota Yaris
You have now entered, the fan is effective only at low speed and the engine off. If the heater does not send air at low speed and you nevertheless hear noise, it means that this fan turns out to be probably faulty. If all goes well, thanks to a higher speed the heating of this Toyota Yaris should work. If the fan does not activate it will have to be changed.
Blocked hoses
His clues are pretty obvious. When your heating blows and creates little or no heat, the malfunction probably comes from the hoses. These become blocked over time and no longer allow hot water to access your heating of this Toyota Yaris. Therefore, clean the hoses or replace them with new ones.
Air pocket in the circuit of the Toyota Yaris
The syndrome is sometimes identical to that of the hoses. If air pockets have entered the circuit, high-temperature water will also have difficulty accessing the heater radiator of the Toyota Yaris. From then on, it will suffice to purge the circuit.
Conclusion
You now know where the dysfunction will come from. That said it happens that the reason comes from another place, like the air duct of this cluttered Toyota Yaris, or a defective tap, however it is unfortunately rather rare. Feel free to leave a comment in case this post helped you. Enjoy the road!
