Astra 1.8 reheating

Sacal it there is no problem as long as it does not snow in your city, if the sensor is evil then change it and test you want the whole problem here in Chile I realize a parallel installation for this type of problem in vehicles such as Crysler so as not to incur gigantic expenses, but the strange thing is that it goes out when it has to enter the second speed you want to be badly connected the cable that enters the elctro and does not close.

Hello, how about the dear friend: Good that they already checked your car,, see if the focus that remains on is a radiator and in the middle of him it is like a fan, they did not repair your module well.
And if you want you can eliminate that module and make a special connection ....
If you have any questions with pleasure ,,,,

Kike thanks this week I will remove the thermostat to see how it works.

Sensortest, because that same error code is the one that is on, and thanks to God it does not rehend but when it goes from 90 degrees it turns on the light of the radiator with a fan in the middle, I no longer know what else to do, what connection can be done to solve that? I thought about thoroughly cleaning the radiated to see if it was something of that, thanks.

Removing the thermostat is not a solution .. The thermostat is very helpful to the engine .. When removing the thermostat you can find more vehicle failures .. I recommend cleaning the radiator first that it will never be more since there are high temperatures ... it could be the water pump or some censor but that would be discarded according to the faults

Hello in the Astra you can try if the entire cooling system is called a fan, reliable and fuses in this way, start it and remove the temperature sensor tab of two pins, it has to start the first speed and then fast, start slowly and then faster. If everything is then you have a mechanical drama. What I told you is to test everything electric and electronic of the car, anything at your disposal
