How a heater works on a Toyota Hi Ace

In winter it is essential on the road when going to work. And when the latter does not turn out well, we very much regret it. Therefore to understand where the problem comes from, we will have to assimilate how it works on the famous Toyota Hi Ace, at least in a simplified way. The heating uses the engine temperature to heat the personalised tour, then in most cases the cooling system. Consequently, this duplicates. Also, the emission system, so that the air arrives in the cabin has a double system. There is a ventilateur which emits air when the vehicle is running at low speed or is stopped, then it is the speed of the vehicle which will send the air once you are driving faster. Well designed, right?

Recurring heating problems on a Toyota Hi Ace

Broken thermostat

The concept is affordable, in the case where the thermostat which regulates the temperature does not understand well the degree of heat of the cooling circuit, the whole circuit is affected. Even if the thermostat of the famous Toyota Hi Ace does not work well, the heating will work normally. Because the natural temperature of the engine will increase over time, and the cooling system the same way, whether the thermostat works or not. The only concern is that you will have trouble regulating the heat emitted.

Air shutters blocked on the Toyota Hi Ace

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 Toyota Hi Ace

As you will understand, the fan is only used at low speed and stopped. If it happens that the heating system does not send heat at all at low speed and yet you still hear its noise, this fan will probably be running. A priori, with more speed the heating of the famous Toyota Hi Ace will work. In case the fan does not work at all it will have to be replaced by a new one.

Blocked hoses

The signs will be fairly simple. When your heating works but does not heat or very little, the problem probably comes from the hoses. They get dirty over time and do not allow hot water to heat the famous Toyota Hi Ace. In this case, remove dirt from the hoses or replace them with new ones.

Air pocket in the circuit of the Toyota Hi Ace

The symptom will be the same as those of the hoses. If it does happen that air pockets have entered the circuit, hot water will also have a hard time getting to the heating radiator of your Toyota Hi Ace. In this case, it is only necessary to purge the circuit.

Conclusion

You now understand where the problem may arise. That said, it may be that the problem originated on the other hand, like the air duct of the famous Toyota Hi Ace obstructed, or even a broken valve, however it is still rather rare. Feel free to leave a comment if this article helped you. Good walk !
