Volvo 2011 1.6 "Cooling riddle diary"

[mrpersa]

I have tried everything else, and now I am looking for my last hope before my precious v50 is being sold in parts.*

The car can´t keep the temperature down, and the AC sounds strange from the passenger side. I will give as a good description as possible.*

Since the car was transformed from a driving school car to normal, the temperature has risen up over normal at many occasions. And I and many others have tried almost everything to fix the problem. The first symptom we believed was a bad gasket, but this have been tested at several mechanics with a pressure test to exclude it. The car isn't leaking cooling liquid so the problem is somewhere else.*

Second hypothesis was that the termostat or water pump was bad, so this was changed, but car is still going high.*

Third hypothesis was that the temperature sensor was bad so this was changed without any difference.*

Fourth hypothesis was that the radiator and fan was bad, so this was also changed without any difference, but here I found something odd. I have electric to the fan, so relay isn't bad, but it seems like it is acting strange, and not working properly. It is not turning on, and when I am giving pressure by my hand, then it seems to get resistance and starts. So I believe here is one hypothesis that can be the problem, but I have tried to replace the whole thing, with the module to the fan, but it was the same. I will attach videos and I hope one guy here can understand where my problem is so I can keep my favorite car.*


I can't upload videos so it is a little hard to explain without them.
