Anyone know the torque for the pulley that you take off for thermostat replacement?

Nm stands for Neuton meters, named after Sir Isaac Neuton.

Look at the PDF I previously posted and I converted Nm to foot pounds.

Major,

What would you consider as initial installation and follow up operations for the guide pulley as stated on the R&I. I just loosened and retightened the bolt on the guide pulley would it be initial or follow up?
Thanks

No. On my ML350 there is a squeaking noise that I'm working to figure out. I changed the v belt a few weeks ago because it was worn out. It got rid of the noise until a few days ago. The noise is back. I tested all the pulleys they're all nice and sound, no wobbling and run quite freely. But I noticed a very tiny wobble on the idler pulley, I loosened the center bolt and retightened it. That's why I thought I torque it the right amount to see what happens.
Here's the squeak in action
