How a heater works on a Toyota Avensis 4
In the middle of winter, it is our best ally on the road when we go to work. And when the latter does not activate well we quickly regret it. So before understanding where the malfunction comes from, it is essential to understand how it works on the famous Toyota Avensis 4, at least its principle. The heating uses engine heat to raise the temperature of the personalised tour, then in most cases the cooling system. So it's a two in one. Also, the fan system, so that the air reaches us also has a duplication. It's the ventilateur which emits air as soon as the vehicle is moving at low speed or at walking pace, then it is the speed of the vehicle which will send the air as soon as you are moving faster. Well designed, right?
Recurring heating problems on a Toyota Avensis 4
Broken thermostat
The concept is simple, if the thermostat which controls the heat does not fully understand the degree of heat in the water circuit, the entire circuit is affected. Even though the thermostat of the famous Toyota Avensis 4 no longer activates well, the heating will still work. Because the heat coming from the engine will gradually increase, and the water circuit too, even without a thermostat. Our only concern is that you will not be able to really set the temperature.
Air shutters blocked on the Toyota Avensis 4
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 Avensis 4
As you will understand, the fan only operates at low speed or the engine is off. If the heater does not emit air at low speed and you still hear a sound, the fan is probably on. Ordinarily, with a higher speed the heater of the famous Toyota Avensis 4 should turn. If the fan does not activate at all, it is better to replace it with a new one.
Blocked hoses
The symptoms are pretty obvious. When your heater is working and creating little or no heat, the problem is most likely with the hoses. The latter become clogged over time and do not allow hot water to reach the heating of the famous Toyota Avensis 4. Therefore, wash the hoses or install new ones.
Air pocket in the circuit of the Toyota Avensis 4
The symptom is identical to that of the hoses. If air streams are stored in the circuit, water will similarly have problems reaching the heater radiator of this famous Toyota Avensis 4. Therefore, it will suffice to purge the circuit.
Conclusion
You now know where your dysfunction could arise. However, it happens that the problem comes from another place, like the air duct of the famous Toyota Avensis 4 cluttered, or a faulty valve, but it is still less frequent. You can write a comment if this post has been useful to you. Enjoy the road!
