Thanks ahead of time to anyone offering info!
I have a 2009 Nitro 4.0 liter R/T with Air Conditioner.
I'm replacing the belt Tensioner and three idler pulleys.
I know the Tensioner mounting bolt is 30-40 Ft. lbs. as it is stamped on the side of the Tensioner assembly.

I need the torque spec for the pulley mounting bolts.
  1. MOPAR > 53013926AA > Idler Pulley
  2. MOPAR > 53013927AA > Idler Pulley
  3. MOPAR > 4891720AA >Idler Pulley

I wonder where I can find the information on short notice. I’m actually right in the middle of the job right now. I guess on the pulleys I will just have to use my best judgment.Thank you for the info you provided.

Thanks for the info! So I found out that Haynes has finally published a Jeep Liberty/Dodge Nitro manual. In the 4.0L V6 Engine section, it lists the idler pulley at 21 Ft. lbs.
