How a heater works on a Toyota Yaris 3
When it is cold it is essential on the way to go to work. And when the latter does not rotate, it is easily noticed. So in order to know where the problem comes from, you have to understand how it works on this Toyota Yaris 3, at least its principle. The heating uses engine heat to heat the personalised tour, and generally the cooling device. In fact it is a two in one. Similarly, the fan device, so that heat comes into the cabin has a dual system. It's the ventilateur which sends the heat when the vehicle is traveling at low speed or not at all, and it is the speed of your automobile which will send the heat when you are driving faster. Pretty well thought out right?
Recurring heating problems on a Toyota Yaris 3
Broken thermostat
The idea is easy, assuming that the thermostat that regulates the temperature does not really measure the degree of heat of the water in the circuit, the whole of the latter is affected. Even if the thermostat of this Toyota Yaris 3 does not activate properly, the heating will work normally. Quite simply because the heat coming from the engine will increase over time, then the water circuit at the same time, whether it is regulated or not. Our only concern is that you can't really adjust the air temperature.
Air shutters blocked on the Toyota Yaris 3
It is a concern that occurs 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 3
As you might expect, the fan is useful only at low speed and in neutral. If it happens that the heating does not generate air at reduced speed but that you still discern a sound, it is that the fan will probably be defective. A priori, thanks to more speed the heating of this Toyota Yaris 3 must work. Assuming that the fan does not activate in any way, it will have to be replaced.
Blocked hoses
Its signs are fairly obvious. When your heating blows but does not heat or very little, the problem probably comes from the hoses. They become blocked over time and no longer allow hot water to reach the heating of this Toyota Yaris 3. In this situation, wash the hoses or install new ones.
Air pocket in the circuit of the Toyota Yaris 3
The symptom is sometimes identical to those of the hoses. If it happens that small pockets of air are inserted within the circuit, the high temperature water will have the same problems to reach the radiator of the heating of this Toyota Yaris 3. In this situation, it will be enough to purge the circuit.
Conclusion
You now know where this concern will come from. On the other hand it may be that the reason comes from another place, for example the air duct of this cluttered Toyota Yaris 3, even a broken tap, but this is still more rare. Leave us a comment if this tutorial was useful to you. Good walk !
