w140 S320 M104 Fan Blade Orientation
 

Hello;

I just replaced my viscous fan clutch, even though I am positive I must have placed the fan blades correctly I did the whole work in quite a rush now I am a bit paranoid if I placed the fan blades correctly or not.

Can anyone PLEASE post a picture of the fan blade orientation of a W140 S320 with a M104 engine, I mean when you look from above are the blades like this "/" or this "\"

Thank You So Much In Advance.

Just turn the engine off while watching the fan blades come to a stop,
The air cutting edge should be in front ..[ towards radiator], b/c the fan turns CCW , looking at the engine from the frontal view...

Notice the blades are cupped ..that should tell you right there...

Hmm, thanks, so this is definately wrong then, I mean the flat end is now on the back and the edges of the flat end seem more thin.

I havent changed it yet but when I flip the blades within the picture the flat end facing radiator, it looks like this, which one is it?

Picture #1 is correct.

Thank You bobs:)

No, it is not wrong....that is correct..
See the leading/cutting edge at the FRONT of the cup of the blade???

It is the the cup that transfers the airflow towards the engine...

Thank You Very Much too Arthur Dalton, you both have been a great assistance. Very Appreciated.

Thank you for the reply.................
