How a heater works on a Toyota Corolla Verso

In the middle of winter it is a definite asset on the trip when you go to work. When it is no longer activated we miss it intensely. In this situation to know what the malfunction came from, it is necessary to know how it works on your Toyota Corolla Verso, at least the basics. The heating uses the engine block temperature to be able to heat the personalised tour, then in most cases the cooling system. In fact this system has several functions. Also, the fan system, so that the hot air comes to us also has a double use. It's the ventilateur which emits hot air when the car is traveling at low speed or not, then the speed of your car will send the hot air once you drive faster. Pretty well thought out right?

Recurring heating problems on a Toyota Corolla Verso

Broken thermostat

The concept is elementary, in the case where the thermostat which regulates the heat does not really capture the temperature of the water circuit, the whole of the latter is impacted. Even if the thermostat of your Toyota Corolla Verso still does not turn correctly, the heating will still work. Because the temperature produced by the engine block will increase little by little, so will the water circuit, whether the thermostat works or not. The only annoyance is that you can't really set the temperature.

Air shutters blocked on the Toyota Corolla Verso

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 Corolla Verso

As you will have understood, the fan is useful only at low speed or in neutral. If the heating system no longer emits air at low speed but you can still discern its noise, it means that the fan will probably be defective. Normally, with higher speed, the heating of your Toyota Corolla Verso will work. In case the fan does not rotate it is better to change it.

Blocked hoses

The clues will be relatively simple. As soon as your heating blows and does not heat or very slightly, the malfunction must undoubtedly come from the hoses. They become dirty over time and no longer allow hot water to reach the heating of your Toyota Corolla Verso. In this specific case, wash the hoses or install new ones.

Air pocket in the circuit of the Toyota Corolla Verso

The symptom happens to be identical to that of the hoses. If small pockets of air are stored in the heart of the circuit, hot water also has trouble reaching the radiator of the heating of the Toyota Corolla Verso. In this case, you just need to purge the circuit.

Conclusion

You now know what can cause the malfunction. Nevertheless it happens that the problem comes on the other hand, for example the air duct of your Toyota Corolla Verso obstructed, or a broken tap, but it is still rarer. Leave us a comment if this tutorial served you. Good walk !
