How does a heater work on a Suzuki Grand Vitara 2

In winter the heating is a definite asset on the commute when going to work. And when the latter does not turn well we quickly regret it. So before knowing where the problem is coming from, you must understand how it works on your Suzuki Grand Vitara 2, at least in a simplified way. The heating uses the heat from the engine block to heat the personalised tour, and very often the cooling mechanism. In fact this system has several functions. In addition, the fan mechanism, so that the heat reaches us also holds a duplication. There is a ventilateur which sends heat when the automobile is moving slowly or is stationary, and it is the speed of the vehicle that will send the heat as soon as you drive faster. Well designed, right?

Recurring problems with a heater on a Suzuki Grand Vitara 2

Broken thermostat

The concept is simple, if the thermostat that regulates the temperature does not really capture the temperature of the cooling circuit, the whole of the latter is affected. Even if the thermostat of your Suzuki Grand Vitara 2 still does not activate properly, the heating will still work. Because the heat produced by the engine block will increase little by little, then the cooling circuit at the same time, even without a thermostat. The only inconvenience is that you can hardly adjust the air temperature.

Air flaps blocked on the Suzuki Grand Vitara 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.

Faulty fan on the Suzuki Grand Vitara 2

As you will understand, the fan is useful only at low speed and the engine is off. If your heater does not emit too much air at low speed and you still hear a sound, it means that the fan is likely to be defective. If all goes well, with a brisk pace the heating of your Suzuki Grand Vitara 2 should be on. If it happens that the fan does not activate at all, it will have to be changed.

Blocked hoses

The signs turn out to be pretty straightforward. When your heater turns on but does not create heat or very little, the malfunction probably comes from the hoses. They get clogged the more time passes and no longer leave the possibility for hot water to reach your heating system in your Suzuki Grand Vitara 2. In this situation, clean the hoses or replace them with new ones.

Air pocket in the circuit of the Suzuki Grand Vitara 2

The symptom will be similar to that of the hoses. In the event that air pockets have entered the heart of the circuit, hot water also has problems reaching the heater radiator of the Suzuki Grand Vitara 2. In this situation, all you have to do is purge the circuit.

Conclusion

You now know where the malfunction is going to come from. On the other hand, it is possible that the reason comes from another place, such as the air duct of your Suzuki Grand Vitara 2 blocked, or even a defective valve, but this is still rather rare.
