How a heater works on a Jeep Cj7

When it is cold it is our best ally on the way to work. And when the latter does not activate we easily regret it. So before finding out where the problem came from, you have to understand how it works on the famous Jeep Cj7, at least its principle. The heating uses the temperature of the engine block to increase the heat of the personalised tour, then very often from the cooling device. In fact, this duplicates. In addition, the fan device, so that the air comes to us also has a double use. It's the ventilateur which sends the air when the car is traveling at low speed or not, then it is the speed of your automobile which allows the air to be sent when you are driving faster. It's pretty clever isn't it?

Recurring heating problems on a Jeep Cj7

Broken thermostat

The concept is affordable, if the thermostat that regulates the temperature does not properly measure the degree of heat of the water circuit, the latter is affected. Even if the thermostat of the famous Jeep Cj7 does not work properly, the heating will still work. Because the temperature coming from the engine block will increase progressively, then the cooling circuit in the same way, even without thermostat. Our only concern is that you will hardly be able to adjust the air temperature.

Air shutters blocked on the Jeep Cj7

It is a concern 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.

Defective fan on Jeep Cj7

As you might expect, the fan is only used at low speed and the engine is off. If your heating does not generate air at low speed and yet you still hear noise, it is good that the fan is certainly running out. Normally, thanks to more speed, the heating of the famous Jeep Cj7 will work. If the fan does not work at all it is better to replace it with a new one.

Blocked hoses

The clues turn out to be quite simple. As soon as your heating works but does not heat or very little, the concern must certainly come from the hoses. They clog up over time and no longer allow hot water to reach the heating of the famous Jeep Cj7. Therefore, clean the hoses or put new ones.

Air pocket in the Jeep Cj7 circuit

The symptom is similar to those of the hoses. If ever air pockets are introduced inside the circuit, the high temperature water has the same way to access the heating radiator of your Jeep Cj7. From then on, you just need to purge the water circuit.

Conclusion

You now know where your concern may come from. However it happens that the problem comes from another place, for example the air duct of the famous Jeep Cj7 cluttered, or a broken tap, but this remains unfortunately rather rare.
