How does a heater work on a Toyota Ft-86 (2)

In the middle of winter, heating is essential on the road when going to work. And when it doesn't work, you notice it intensely. So in order to know where the problem comes from, it is essential to understand how it works on your Toyota Ft-86 (2), at least in a simplified way. The heating uses heat from the engine block to increase heat from the personalised tour, then in most cases the cooling system. In fact this system has several functions. In addition, the fan system, so that the air reaches us also has a duplication. There is a ventilateur which sends air when the vehicle is running at low speed or is stationary, then it is speed of your automobile which will send the air when you are going at high speed. Rather well thought out, no?

Recurring problems with a heater on a Toyota Ft-86 (2)

Broken thermostat

The idea is easy, assuming that the thermostat which regulates the heat does not properly understand the degree of heat of the water circuit, the latter is affected. Even if the thermostat in your Toyota Ft-86 (2) still does not work properly, the heating will still work. Quite simply because the heat produced by the engine block will gradually increase, and the cooling circuit at the same time, even without a thermostat. The only inconvenience is that you will hardly be able to set the heat emitted.

Air flaps blocked on the Toyota Ft-86 (2)

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.

Fan defective on the Toyota Ft-86 (2)

As you can imagine, the fan is only used at low speed or in neutral. If it happens that the heating system does not send heat at all at low speed but you still hear its noise, it is because your fan is probably broken. Generally, at a brisk pace the heating of your Toyota Ft-86 (2) should turn on. If the fan does not work at all, it will have to be replaced by a new one.

Blocked hoses

Its symptoms will be quite simple. When your heater blows but does not create heat or very little, the problem is most likely with the hoses. These become clogged over time and do not allow hot water to reach the heating of your Toyota Ft-86 (2). So wash the hoses or install new ones.

Air pocket in the circuit of the Toyota Ft-86 (2)

The syndrome is sometimes the same as that of the hoses. If it happens that the air streams are encrusted inside the circuit, the water also has difficulty accessing the heating radiator of your Toyota Ft-86 (2). So, you just have to purge the water circuit.

Conclusion

You now know where the problem will arise. On the other hand, it happens that the problem comes from elsewhere, for example the air duct of your Toyota Ft-86 (2) cluttered, or a broken valve, but it is still rarer. Leave us a comment if this tutorial has helped you. Enjoy the road!
