How a heater works on a Toyota 4runner
When it's cold it's a definite asset on the road when you go to work. And when the latter does not turn it is easily missed. In this situation to know where the problem came from, you have to understand how it works on this Toyota 4runner, at least the basics. The heating uses engine temperature to raise the temperature of the personalised tour, and in most cases of the cooling mechanism. In this way it duplicates. Also, the emission mechanism, so that the hot air comes into the cabin has a double system. There is a ventilateur which emits hot air as soon as the vehicle is traveling at low speed or is stopped, and it is the speed of your automobile which will send hot air when you are traveling faster. Well designed, right?
Recurring heating problems on a Toyota 4runner
Broken thermostat
The concept is elementary, when the thermostat which regulates the temperature does not really understand the degree of heat of the water in the circuit, the latter is impacted. Even if the thermostat of this Toyota 4runner still does not turn well, the heating will still work. Because the temperature coming from the engine will increase gradually, then the water circuit in the same way, whether the thermostat works or not. The only hassle is that you won't be able to really control the heat emitted.
Air shutters blocked on the Toyota 4runner
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 4runner
You have now entered, the fan is useful only at low speed and in neutral. If your heating system does not emit air at low speed and yet you still hear its noise, this fan is most likely to be screwed up. Normally, thanks to a brisk pace the heating of this Toyota 4runner should work. If the fan does not rotate, it must be replaced.
Blocked hoses
His clues will be rather simple. As soon as your heating works but does not create or little heat, the problem certainly comes from the hoses. They become blocked over time and no longer allow hot water to reach the heating of this Toyota 4runner. In this case, wash the hoses or install new ones.
Air pocket in the circuit of the Toyota 4runner
The symptom will be the same as those of the hoses. If air pockets are stored in the circuit, the high temperature water will also have a hard time getting to the heating radiator of this famous Toyota 4runner. In this case, simply purge the water circuit.
Conclusion
You now know where this problem may arise. However it happens that the problem comes from elsewhere, such as the air duct of this Toyota 4runner clogged, or even a defective valve, however it is still rather rare. You can write a comment if this text has helped you. See you soon !
