N62 4.4 Belt tensioner torque
 

I am replacing my water pump and both belt tensioners along with idler pulley. I can not find a torque spec for the idler and tensioner fasteners. Does anyone here have that info handy? I have found no reliable info in a google search, and the bentley manual has nothing.

Should be in here...

Bentley should have a page with torque by size eg 8mm bolt gets 50 N·m torque. You can use as a starting point until you find a specific variance

If not in Bentley, you can find that same general torque guide for BMW online.

PS I just had to change my alternator and I tightened them until I made a "click" with my tongue. I was using a 1' breaker bar and tugged pretty good I did not pull out my torque wrench.
