The car, when the engine is cold, but also when it is warm, as soon as I start the car the radiator fan starts at the third speed. No errors in the diagnosis. Sensor on the cylinder head reports regular temperature. Replaced thermostatic valve, 2 times (not original) in parameters with ignition on fan relay activation 1 2 3 off, as soon as I start the engine they are activated on ON. Sometimes it happens that the second speed starts instead of the third, have similar cases happened?
