How a heater works on a Toyota Hilux 2

In winter it is a definite asset on the journey when going to work. And when it does not work well we quickly regret it. So in order to know where the problem came from, it is essential to know how it works on this Toyota Hilux 2, or at least the main lines. The heating uses the temperature of the engine block to raise the temperature of the personalised tour, then very often the cooling mechanism. So it's a two in one. In a similar way, the emission mechanism, so that heat comes into the interior also presents a double use. It's the ventilateur which sends the heat as soon as the car is running at low speed or not at all, then it is the speed of the car which sends the heat when you are driving at high speed. Well designed, right?

Recurring heating problems on a Toyota Hilux 2

Broken thermostat

The concept is affordable, in the case where the thermostat which regulates the temperature does not really capture the degree of heat of the water circuit, the latter is affected. Even if the thermostat of this Toyota Hilux 2 no longer works properly, the heating will still work. Quite simply because the temperature produced by the engine block will increase progressively, then the water circuit in the same way, whether it is regulated or not. Our only concern is that you will hardly be able to change the temperature.

Air shutters blocked on the Toyota Hilux 2

This is a problem that occurs fairly 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 Hilux 2

As you might expect, the fan is useful only at low speed or in neutral. If this heating system does not generate any heat at low speed at all and you still hear a sound, it is good that the fan will certainly be screwed up. If all goes well, with a higher speed the heating of this Toyota Hilux 2 should work. If the fan does not work, it will have to be replaced.

Blocked hoses

Its signs will be fairly obvious. If your heating blows and does not heat or very slightly, the problem must probably come from the hoses. These become blocked over time and no longer allow hot water to reach your heating in this Toyota Hilux 2. In this case, remove the hoses or replace them with new ones.

Air pocket in the circuit of the Toyota Hilux 2

The syndrome is sometimes identical to that of the hoses. If ever air bubbles are encrusted inside the circuit, high-temperature water will also have a hard time reaching the heating radiator of your Toyota Hilux 2. In this case, you just need to purge the circuit.

Conclusion

You now understand where your problem may come from. That said it is possible that the concern comes from elsewhere, for example the air duct of this cluttered Toyota Hilux 2, even a broken tap, but it is still rather rare. Leave us a comment if this article was useful to you. Good road !
