How a heater works on a Toyota Land Cruiser Serie 120

In the middle of winter it is a definite asset on the journey when going to work. And when the latter does not work well we notice it quickly. So before knowing where the problem comes from, we must understand how it works on this Toyota Land Cruiser Serie 120, at least its principle. The heating uses the temperature of the engine block to increase the heat of the personalised tour, then very often from the cooling mechanism. So it's a two in one. In a similar way, the emission mechanism, so that the hot air reaches the cabin has a double system. It's the ventilateur which emits hot air when the automobile rolls slowly or or not at all, then it is speed of your automobile which will send the hot air when you are traveling faster. Well designed, right?

Recurring heating problems on a Toyota Land Cruiser Serie 120

Broken thermostat

The idea is affordable, in the event that the thermostat which regulates the heat does not really capture the degree of heat of the water in the circuit, the entire latter is impacted. Even if the thermostat of this Toyota Land Cruiser Serie 120 still does not work well, the heating will work normally. Because the temperature coming from the engine block will gradually increase, then the water circuit in the same way, even without a thermostat. The only concern is that you will not be able to really regulate the heat emitted.

Air shutters blocked on the Toyota Land Cruiser Serie 120

This is a problem that happens quite often. 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.

Faulty fan on the Toyota Land Cruiser Serie 120

As you will understand, the fan is useful only at low speed or with the engine off. If the heater doesn't emit any air at all at low speed and you still hear noise, then this fan is most likely run out. A priori, with more speed the heating of this Toyota Land Cruiser Serie 120 should work. If it happens that the fan really does not work, it will have to be changed.

Blocked hoses

The signs will be quite simple. If your heater is blowing but creating little or no heat, the problem is likely with the hoses. The latter become clogged as time goes by and no longer allow hot water to access the heating of this Toyota Land Cruiser Serie 120. In this case, de-clog the hoses or put new ones.

Air pocket in the circuit of the Toyota Land Cruiser Serie 120

The syndrome will be identical to that of the hoses. In case air pockets are encrusted in the circuit, water also has problems to access the heating radiator of this Toyota Land Cruiser Serie 120. In this case, you just have to bleed the circuit.

Conclusion

You now understand from where this problem can arise. However, it happens that the reason comes on the other hand, for example the air duct of this Toyota Land Cruiser Serie 120 is blocked, or a faulty valve, however it is still less frequent.
