Hello,

Last week I climb hill and after that I hear something wrong in the engine hood.

Check and fan blade scratch radiator because waterpump bearing play a lot.

Why does it happened? I use high quality skf waterpump does is it the weakness of fan clutch cooling? Im afraid this will repeat again next

Thank.you
Markus

Will do check engine mount tomorrow, but as I see the waterpump bearing is collapsed and have huge play.

What does cause this? Because of wrong use number of fan blade? Mine use 11 blades so may be too many blades will force the waterpump bearing to collapsed?

The gap between fan blade with radiator is about only 1 finger or about 0.5 inch, car in normal flat surface before this happened.

This happened after I climb mountain and down hill, does it is the cause?
