Hi,
My problem is that the radiator fan never stops spinning at full speed. It never idles. The coupler is stiff when cool. Not only can you not spin the fan, but if you force it a bit, it returns to the same position. Impossible to raise the engine temperature above a third on the gauge.
I have this setup:
As far as I and several mechanics can tell, there is nothing wrong with the installation. The water pump is correct for the coupler. As we understand it, there should be no sorcery involved, just mount it it on with the correct bolts and spacers, make sure it’s not touching anything and let it do it’s job. The coupler has maybe 500km on it. I have another, unused, which is the same. A third, used coupler from another car is only a bit less stiff. So it’s unlikely they are all malfunctioning. What are we doing wrong?
