How a heater works on a Kia Rocsta
In winter he is our best ally on the way to work. And when the latter does not turn well we notice it quickly. Therefore to know where the problem comes from, you must understand how it works on your Kia Rocsta, or at least the main lines. The heating uses the heat from the engine to heat the personalised tour, then very often the cooling mechanism. So it's a two in one. Also, the fan mechanism, so that the heat comes into the cabin also has a dual purpose. It's the ventilateur which emits heat when the car is running at low speed or not, then it is the speed of your car which allows the heat to be sent as soon as you move faster. Well designed, right?
Recurring heating problems on a Kia Rocsta
Broken thermostat
The idea is elementary, when the thermostat which regulates the temperature does not really capture the degree of heat of the water in the circuit, the latter is affected. Even if your Kia Rocsta's thermostat does not work correctly, the heating will still work. Because the heat produced by the engine will increase gradually, then the water circuit in the same way, whether it is regulated or not. The only annoyance is that you can't really change the air temperature.
Air shutters blocked on the Kia Rocsta
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.
Faulty fan on the Kia Rocsta
As you will have understood, the fan only works at low speed or the engine off. In case this heater does not emit too much heat at low speed and yet you nevertheless perceive noise, it is good that the fan will certainly be screwed up. Normally, with a high speed, the heating of your Kia Rocsta will be able to turn. If the fan does not work at all it should be changed.
Blocked hoses
Its symptoms will be fairly simple. As soon as your heating works but does not heat or very little, the problem must probably come from the hoses. These clog more time passes and do not allow hot water to access until the heating of your Kia Rocsta. In this case, unclog the hoses or put new ones.
Air pocket in the Kia Rocsta circuit
The symptom is similar to that of the hoses. If air streams are inserted inside the circuit, high temperature water also has difficulty reaching the radiator of the Kia Rocsta heater. In this case, all you have to do is purge the circuit.
Conclusion
You now understand where the problem can arise. That said, the problem may come from another source, such as the air duct of your clogged Kia Rocsta, or a defective valve, but it is still quite rare. Leave us a comment if this article was useful to you. Good road !
