How a heater works on a Toyota Rav 4 (2th Generation)

In the middle of winter it is our best ally on the way when we go to work. And when it stops working we notice it quickly. Therefore, in order to know what is the source of the problem, it is essential to assimilate how it works on your Toyota Rav 4 (2nd Generation), at least its principle. The heating uses engine temperature to raise the temperature of the personalised tour, then in most cases of the cooling mechanism. Consequently, this duplicates. Similarly, the fan mechanism, so that air enters the cabin also has a dual purpose. It's the ventilateur which sends the air as soon as the vehicle is traveling at low speed or is stopped, then it is the speed of the car which will send the air when you are driving faster. Well designed, right?

Recurring heating problems on a Toyota Rav 4 (2th Generation)

Broken thermostat

The concept is elementary, if the thermostat which regulates the temperature does not measure the degree of heat of the water circuit well, the latter is affected. Even if the thermostat of your Toyota Rav 4 (2nd Generation) does not turn well, the heating will work normally. Because the temperature produced by the engine will gradually increase, and the water circuit in the same way, even without a thermostat. Our only concern is that you will hardly be able to regulate the heat emitted.

Air shutters blocked on the Toyota Rav 4 (2th Generation)

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.

Defective fan on the Toyota Rav 4 (2th Generation)

You have now entered, the fan is useful only at low speed or the engine off. If this heating system does not emit too much air at low speed but you nevertheless discern its noise, it is that your fan turns out to be undoubtedly defective. As a general rule, with more speed, the heating of your Toyota Rav 4 (2nd Generation) should work. If the fan does not rotate at all, it should be replaced by a new one.

Blocked hoses

Its signs will be relatively simple. In the event that your heating turns but does not heat or very slightly, the problem probably comes from the hoses. These become blocked over time and do not allow hot water to reach your heating of your Toyota Rav 4 (2nd Generation). In this case, remove dirt from the hoses or replace them with new ones.

Air pocket in the circuit of the Toyota Rav 4 (2th Generation)

The symptom will be the same as those of the hoses. If ever air streams are stored in the heart of the circuit, the water also has trouble reaching the radiator of the heating of this famous Toyota Rav 4 (2nd Generation). In this case, it is necessary to purge the water circuit.

Conclusion

You now know what could be causing the problem. By cons it is possible that the problem comes from the other hand, for example the air duct of your Toyota Rav 4 (2nd Generation) clogged, or a defective valve, however it is still rather rare.
