Re: Hydraulic Fan Behaviour
The hydraulic cooling fan should spin with approx 500 rpm as soon as you start the engine. Did you try to turn the fan by hand, to feel if its spinning freely? There is a bit of resistance, but not too much.
If you switch the AC on, then the fan not necessarily should spin faster, this depends on a pressure signal from the AC pressure sensor.
How is the power steering, does it feel normal?
