How a heater works on a Suzuki Grand Vitara
When it is cold it is a definite asset on the road when you go to work. And when it is no longer activated we notice it quickly. So in order to find out what the problem comes from, it is necessary to know how it works on this Suzuki Grand Vitara, at least in a simplified way. The heating uses the engine temperature to raise the temperature of the personalised tour, then very often from the cooling system. In fact, this duplicates. In addition, the fan system, so that the heat arrives in the cabin has a double system. It's the ventilateur which sends the heat when the car is driving slowly or not at all, then it is the speed of the car which makes it possible to send the heat once you are driving faster. It's pretty clever isn't it?
Recurring heating problems on a Suzuki Grand Vitara
Broken thermostat
The idea is elementary, if the thermostat which adjusts the temperature does not really capture the temperature of the water in the circuit, the latter is affected. Even if the thermostat of this Suzuki Grand Vitara does not activate properly, the heating will operate normally. Because the temperature coming from the engine will increase progressively, then the water circuit too, whether the thermostat works or not. The only annoyance is that you cannot really control the heat emitted.
Air shutters blocked on the Suzuki Grand Vitara
It is a concern that happens quite 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 Suzuki Grand Vitara
As you might expect, the fan is only used at low speed or in neutral. If this heating system no longer emits air at reduced speed and you still hear noise, this means that the fan is probably faulty. If all goes well, thanks to a high speed the heating of this Suzuki Grand Vitara will work. If the fan never activates in any way, it is better to replace it with a new one.
Blocked hoses
The clues turn out to be quite simple. When your heater is running and creating little or no heat, the concern is likely to be from the hoses. These become blocked over time and do not allow hot water to reach the heating of this Suzuki Grand Vitara. Therefore, remove the hoses or put new ones.
Air pocket in the circuit of the Suzuki Grand Vitara
The syndrome is the same as that of the hose lines. In case air streams are stored inside the circuit, high temperature water will also have problems reaching the radiator of the heating of this Suzuki Grand Vitara. Therefore, simply purge the circuit.
Conclusion
You now understand what will cause this concern. However it happens that the problem comes from another place, for example the air duct of this cluttered Suzuki Grand Vitara, or a defective tap, however it is still more rare. Leave us a comment in case this text served you. Enjoy the road!
