How a heater works on an Opel Rak E
When it is cold it is a definite asset on the way to work. And when it doesn't work, we very much regret it. So to understand what caused the malfunction, it is necessary to understand how it works on this Opel Rak E, at least in a simplified way. The heating uses the heat from the engine block to heat the personalised tour, and generally the cooling system. So it's a two in one. Similarly, the fan system, so that the heat reaches us also has a double use. It's the ventilateur which sends the heat as soon as the car is running at low speed or not at all, and it is the speed of the car which allows the heat to be sent when you are driving at high speed. Pretty well thought out right?
Recurring heating problems on an Opel Rak E
Broken thermostat
The concept is affordable, assuming that the thermostat that regulates the temperature does not really capture the degree of heat of the water in the circuit, the entire circuit is affected. Even if the thermostat of this Opel Rak E still does not work well, the heating will still work. Because the heat produced by the engine block will increase over time, and the cooling circuit too, whether it is regulated or not. Our only annoyance is that you will not be able to really control the heat emitted.
Air shutters blocked on the Opel Rak E
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.
Faulty fan on the Opel Rak E
As you will understand, the fan is useful only at low speed and the engine off. If your heating system does not send any heat at low speed but you still hear its noise, it is that this fan turns out to be definitely defective. A priori, with a higher speed the heating of this Opel Rak E will work. If it happens that the fan does not work at all it should be changed.
Blocked hoses
The symptoms turn out to be fairly obvious. When your heating works and does not heat or little, the malfunction must undoubtedly come from the hoses. These get dirty over time and no longer allow hot water to access until the heating of this Opel Rak E. In this situation, remove the hoses or install new ones.
Air pocket in the circuit of the Opel Rak E
The syndrome is found to be similar to that of the durits. If air pockets are stored in the circuit, water also has problems reaching the radiator of your Opel Rak E heating. In this situation, it is only necessary to purge the water circuit .
Conclusion
You now know what may cause your dysfunction. That said it is possible that the problem comes from elsewhere, such as the air duct of this clogged Opel Rak E, or a broken valve, but it is still more rare. Do not hesitate to leave a comment if this post served you well. Good walk !
