belt replacement - tensioner torque spec?

Hi!
From searching around I think I've got a handle on the belt replacement process, except the re-tightening of the tensioner bolt on reassembly... None of the articles mentioned a torque spec. I feel a bit weird just doing it up to the third grunt. That was great for big old American cars, but with the mix of alloy and plastic in these cars I'd feel better if I had a number to work to... Any thoughts?
Thanks!

From an M272 manual, it is 25NM (about 18ft/lbs) if pre-tapped or 35NM if new - Unless someone with an M111 manual comes in, to be on the safe side, I'd go 20NM (15lbs/ft) with a dab of loctite. This certainly will not strip the threads.

On the gruntability scale - not quite the first grunt...
