How a heater works on a Toyota Auris 2 Tourings

In the middle of winter it is our best ally on the way when we go to work. And when it does not activate we quickly regret it. In this situation in order to understand where the problem comes from, it is necessary to understand how it works on this Toyota Auris 2 Tourings, at least its principle. The heating uses heat from the engine block to increase heat from the personalised tour, and very often the cooling system. Therefore this system has several functions. In addition, the fan system, so that the heat arrives in the interior presents a double system. It's the ventilateur which emits heat when the vehicle is running at low speed or is stopped, and it is the speed of the vehicle which will send heat when you are driving faster. It's pretty clever isn't it?

Recurring heating problems on a Toyota Auris 2 Tourings

Broken thermostat

The idea is easy, in the case where the thermostat which regulates the temperature does not measure the temperature of the cooling circuit well, the latter is affected. Even if the thermostat of this Toyota Auris 2 Tourings does not turn correctly, the heating will still work. Because the heat coming from the engine block will increase over time, then the water circuit in the same way, even without a thermostat. The only annoyance is that you will have trouble controlling the temperature.

They become blocked over time and no longer allow hot water to reach the heating of this Toyota Auris 2 Tourings. In this situation, clean the hoses or put new ones.

Air pocket in the circuit of the Toyota Auris 2 Tourings

The syndrome is sometimes similar to that of the durits. If it happens that air streams are inserted within the circuit, hot water also has trouble reaching the radiator of the heating of the Toyota Auris 2 Tourings. In this situation, it will suffice to purge the water circuit.
