How a heater works on a Toyota Highlander 2
In the middle of winter it is a definite asset on the road when you go to work. And when it doesn't work well, we very much regret it. So in order to know where the malfunction comes from, it is necessary to understand how it works on this Toyota Highlander 2, at least the basics. The heating uses the heat from the engine block to heat the personalised tour, and generally the cooling system. Consequently, this duplicates. Similarly, the emission system, so that the heat comes to us also has a dual purpose. There is a ventilateur which sends the heat as soon as the car is driving slowly or not, and it is the speed of your car which will send the heat when you are driving faster. Pretty well thought out right?
Recurring heating problems on a Toyota Highlander 2
Broken thermostat
The idea is easy, in case the thermostat that regulates the heat does not really understand the temperature of the water in the circuit, the latter is impacted. Even if the thermostat of this Toyota Highlander 2 no longer works correctly, the heating will still work. Because the heat produced by the engine block will gradually increase, so the water circuit in the same way, whether the thermostat works or not. Our only concern is that you will not be able to really modify the heat emitted.
Air shutters blocked on the Toyota Highlander 2
It is a dysfunction that happens 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 Highlander 2
You have now entered, the fan only operates at reduced speed or the motor off. If your heating system does not generate heat at low speed at all, but you still hear noise, this fan is probably faulty. If all goes well, with a high speed the heating of this Toyota Highlander 2 should turn. Assuming that the fan does not work in any way, it is better to change it.
Blocked hoses
Its signs turn out to be relatively simple. When your heating turns and does not generate little or no hot air, the malfunction is probably due to the hoses. These clog more the time passes and do not allow hot water to reach the heating of this Toyota Highlander 2. Therefore, remove the hoses or install new ones.
Air pocket in the circuit of the Toyota Highlander 2
The syndrome is sometimes the same as that of the hose lines. In the event that air streams are stored in the circuit, hot water has problems in the same way to reach the radiator of the heating of this Toyota Highlander 2. Therefore, it is necessary to purge the circuit.
Conclusion
You now know where this dysfunction can come from. However it sometimes happens that the problem comes from another place, such as the air duct of this clogged Toyota Highlander 2, or even a defective tap, but this is still less frequent.
