How does a heater work on a Toyota Fchv-4
In the middle of winter it is essential on the road when going to work. And when the latter no longer works, we quickly miss it. Therefore to understand where the malfunction comes from, it is necessary to know how it works on the famous Toyota Fchv-4, at least the basics. The heating uses the engine temperature to increase the heat of the personalised tour, then very often from the cooling mechanism. In fact it is a two in one. In addition, the fan mechanism, so that the heat comes to us also presents a duplication. It's the ventilateur which emits heat when the car is moving slowly or or not at all, then it is speed of your automobile which will send the heat once you are moving faster. Rather well thought out, no?
Recurring problems with a heater on a Toyota Fchv-4
Broken thermostat
The concept is elementary, if the thermostat which regulates the heat does not really understand the degree of heat of the water circuit, the latter is affected. Even if the thermostat of the famous Toyota Fchv-4 no longer works correctly, the heating will still work. Because the temperature coming from the engine will increase over time, so will the cooling system, whether the thermostat is on or not. The only concern remains that you will hardly be able to set the air temperature.
Air flaps blocked on the Toyota Fchv-4
It is a dysfunction 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 Fchv-4
As you might expect, the fan is useful only at low revs or with the engine off. If this heating system does not send air at low speed and you still hear a sound, it means that your fan is certainly defective. If all goes well, with more speed the heater of the famous Toyota Fchv-4 will work. If the fan really does not work, it will have to be replaced by a new one.
Blocked hoses
His signs will be rather simple. If your heater is blowing and does not generate hot air or very slightly, the malfunction probably stems from the hoses. These become clogged over time and no longer leave the possibility for hot water to reach the heating of the famous Toyota Fchv-4. In this specific case, clean the hoses or put new ones.
Air pocket in the circuit of the Toyota Fchv-4
The syndrome is identical to those of the hoses. If air pockets are stored in the heart of the circuit, hot water also has problems reaching the heating radiator of your Toyota Fchv-4. In this specific case, you just have to purge the circuit.
Conclusion
You now understand where this dysfunction could arise. On the other hand, it happens that the problem comes from the other hand, such as the air duct of the famous Toyota Fchv-4 cluttered, or even a defective valve, however it is still less frequent.
