Serpentine tensioner pulley torque spec?

[dace voit]

I'm replacing the alternator in Butters(at 80k :/) and the idler and tensioner pulleys for the serp belt. I found the idler torque spec but not the tensioner spec. Anybody can point me in the right direction please? Also, is there a good way to hold the tensioner while torqueing? FWIW, the tensioner is still mounted on the engine.

Thanks for that.

The star looks to be tensioner assembly to block but I need the pulley to tensioner torque. Above it looks like idler #1 and 2 both have a torque of 25, that makes sense considering the bolt size. I now need a good way to hold the tensioner when torqueing the pulley bolt...

I just saw 27ft-lbf in 2001LC FSM, while doing a T-belt last week. But go easy. If torque wrench not calibrated, this is into aluminum. Use care as to which side of pulley toward engine and that it seated correctly before torquing.
