How a heater works on a Seat 133
In winter it is essential on the road when going to work. And when the latter does not work well, we very much regret it. So to find out where the problem came from, it is necessary to understand how it works on this Seat 133, or at least the main lines. The heating uses the heat from the engine block to raise the temperature of the personalised tour, then very often the cooling mechanism. Therefore it is a two in one. Also, the emission mechanism, so that the air reaches us presents a double system. It's the ventilateur which emits air as soon as the vehicle is running at low speed or is stopped, then it is the speed of the car which will send air as soon as you drive at high speed. Well designed, right?
Recurring heating problems on a Seat 133
Broken thermostat
The idea is affordable, when the thermostat which regulates the temperature does not really understand the temperature of the water in the circuit, the entire circuit is affected. Even if the thermostat of this Seat 133 still does not turn properly, the heating will still work. Because the heat coming from the engine block will increase over time, and the water circuit in the same way, whether it is regulated or not. Our only inconvenience is that you will have trouble setting the temperature.
Air shutters blocked on the Seat 133
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.
Faulty fan on the Seat 133
As you might expect, the fan is only used at reduced speed and stopped. If it happens that your heating system does not emit heat at low speed at all but that you still discern a sound, it means that the fan will certainly be screwed up. If all goes well, thanks to more speed the heating of this Seat 133 will be able to turn. Assuming that the fan does not really rotate, it will have to be replaced by a new one.
Blocked hoses
The signs are pretty simple. In the event that your heating works but does not create little or no heat, the problem must certainly come from the hoses. They get dirty the more time passes and do not allow hot water to reach your heating of this Seat 133. So, remove the hoses or replace them with new ones.
Air pocket in the Seat 133 circuit
The syndrome will be the same as those of the hoses. If it happens that pockets of air are introduced into the circuit, the water will also have trouble getting to the radiator of the heating of this famous Seat 133. Then, it will be enough to purge the circuit.
Conclusion
You now know where this concern can arise. Nevertheless it is possible that the concern comes from another place, for example the air duct of this obstructed Seat 133, or a defective valve, however it is unfortunately more rare. Feel free to leave a comment if this post helped you. See you soon !
