How a heater works on a Toyota Corolla 5

When it's cold, heating is essential on the road when you go to work. And when the latter does not work we regret it intensely. In this situation to know where the problem is coming from, you need to know how it works on your Toyota Corolla 5, at least the basics. The heating uses the heat from the engine block to heat the personalised tour, and generally of the cooling system. In this way, this system has several functions. In a similar way, the fan system, so that the hot air reaches us also has a duplication. It's the ventilateur which sends hot air when the vehicle is moving slowly or not at all, and it is the speed of the vehicle that allows the hot air to be sent as soon as you are moving at high speed. Pretty smart isn't it?

Recurring heating problems on a Toyota Corolla 5

Broken thermostat

The concept is affordable, when the thermostat that regulates the temperature does not actually capture the temperature of the cooling circuit, the latter is affected. Even though the thermostat of your Toyota Corolla 5 no longer activates properly, the heating will still work. Quite simply because the heat coming from the engine block will increase little by little, and the cooling circuit in the same way, whether the thermostat is working or not. The only concern is that you will have a hard time changing the air temperature.

Air shutters blocked on the Toyota Corolla 5

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 Corolla 5

As you will understand, the fan is effective only at low speed and the engine is off. If ever this heating system does not send heat at low speed but you still hear a sound, it is good that this fan certainly turns out to be screwed. Normally, thanks to the higher speed the heater in your Toyota Corolla 5 should work. Assuming that the fan does not activate at all, it will have to be replaced.

Blocked hoses

His clues are pretty straightforward. As soon as your heater blows and does not heat or very little, the problem is probably from the hoses. These become clogged over time and no longer allow hot water to reach the heating of your Toyota Corolla 5. In this situation, clean the hoses or install new ones.

Air pocket in the circuit of the Toyota Corolla 5

The symptom will be similar to those of the hoses. If ever threads of air are inserted into the circuit, high temperature water will similarly have difficulty accessing the heater radiator of this Toyota Corolla 5. In this situation, it will suffice to bleed the circuit.

Conclusion

Now you know what the worry can be. Having said that, it is possible that the problem comes from another place, such as the air duct of your cluttered Toyota Corolla 5, or a broken valve, but it is still rarer. You can write a comment if this post helped you. Enjoy the road!
