How does a heater work on a Renault Juvaquatre
Winter is essential on the way when going to work. When it no longer works we miss it intensely. So before understanding where the problem comes from, it is essential to understand how it works on the famous Renault Juvaquatre, at least its principle. The heating exploits the heat of the engine block to be able to increase the heat of the personalised tour, and generally the cooling system. So it's a two in one. In addition, the emission system, so that the air reaches us also has a double use. It's the ventilateur which emits air when the vehicle is traveling at low speed or not, and it is the speed of your automobile which will send the air when you drive faster. Well designed, right?
Recurring heating problems on a Renault Juvaquatre
Broken thermostat
The concept is elementary, when the thermostat which makes it possible to regulate the temperature does not understand well the temperature of the water in the circuit, the latter is affected. Even if the thermostat of the famous Renault Juvaquatre does not work properly, the heating will still work. Because the heat coming from the engine block will gradually increase, then the water circuit in the same way, even without a thermostat. The only concern is that you can't really set the air temperature.
Air flaps blocked on the Renault Juvaquatre
This is a problem that occurs 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 Renault Juvaquatre
As you might expect, the fan is only used at low speed and the engine is off. If it happens that this heating system does not generate too much heat at low speed and that nevertheless you perceive noise all the same, it is that the fan turns out to be probably broken down. A priori, with a higher speed the heating of the famous Renault Juvaquatre should turn. If it happens that the fan does not work at all, it will have to be replaced by a new one.
Blocked hoses
His clues are quite simple. When your heating works and does not heat or very slightly, the problem must probably come from the hoses. They get dirty over time and no longer allow hot water to heat the famous Renault Juvaquatre. In this case, clean the hoses or put new ones.
Air pocket in the Renault Juvaquatre circuit
The symptom is found to be similar to that of the hoses. If it happens that air bubbles have gotten inside the circuit, hot water also has problems reaching the heating radiator of your Renault Juvaquatre. In this specific case, it will suffice to purge the circuit.
Conclusion
You now understand where your problem may arise. By cons it happens that the problem comes from another place, such as the air duct of the famous Renault Juvaquatre cluttered, or a defective valve, however it is unfortunately rather rare.
