How does a heater work on a Toyota Rav 4

When it's cold it's our best ally on the road when we go to work. And when the latter no longer works, we notice it quickly. In this case to know what the problem came from, it is necessary to understand how it works on this Toyota Rav 4, at least the basics. The heating exploits the temperature of the engine block in order to warm the personalised tour, then in most cases the cooling system. In this way, this system has several functions. In addition, the emission system, so that the air reaches us also presents a duplication. There is a ventilateur which emits air when the car is running at low speed or is stationary, then it is the speed of your automobile which will send the air as soon as you are moving at high speed. Pretty smart isn't it?

Recurring problems with a heater on a Toyota Rav 4

Broken thermostat

The notion is easy, in the case where the thermostat which regulates the heat does not really understand the degree of heat of the cooling circuit, the latter is affected. Even if the thermostat in this Toyota Rav 4 no longer works correctly, the heating will work normally. Due to the fact that the natural temperature of the engine block will gradually increase, and the cooling circuit at the same time, even without a thermostat. The only problem remains that you will hardly be able to modify the heat emitted.

Air flaps blocked on the Toyota Rav 4

This is a problem 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 Rav 4

As you would expect, the fan only runs at low speed or the motor is off. If it happens that the heater does not emit air at all at low speed and yet you still discern noise, then this fan is certainly going to be defective. Normally, thanks to the higher speed the heater in this Toyota Rav 4 should work. If it happens that the fan really does not work, it will have to be replaced by a new one.

Blocked hoses

Its signs turn out to be relatively simple. When your heater blows and does not heat or only slightly, the problem must undoubtedly come from the hoses. These become clogged over time and no longer leave the possibility for hot water to reach the heating of this Toyota Rav 4. In this situation, clean the hoses or put new ones.

Air pocket in the circuit of the Toyota Rav 4

The syndrome is found to be similar to those of hoses. If it happens that air streams are stored inside the circuit, the hot water also has problems reaching the heater radiator of the Toyota Rav 4. In this situation, it will suffice to bleed the circuit d. 'water.

Conclusion

You now know where this problem can come from. However it is possible that the reason comes from elsewhere, such as the air duct of this Toyota Rav 4 blocked, or a broken valve, however it is unfortunately rather rare. You can write a comment if this text helped you. See you soon !
