What Joe said, plus, just so there's no misunderstanding - the tensioning bolt (jack bolt) does *not* get torqued - only the bolt that locks in the adjustment (in that sketch, no. 2). (Sorry if that sounds obvious, but I have learned not to assume what people do and do not understand.)
And - yes - the locking bolt torque spec. is the same for all belt adjustment locking bolts on 2.7 and 3.2/3.5.
Also - on the 2.7 a.c. belt tensioner, there is no tensioning bolt - only a locking bolt. There is a spring built into the tensioner bracket that tensions the belt - you lock in that tension with the locking bolt once the belt is on. You also have to remove the tensioner before putting the new belt on and put the end of the spring into the correct slot of the tensioner bracket depending on if the belt is new or pre-used. (See FSM for details and sketch.)
On all but the 2.7 a.c. belt, you tension for 1/4 to 3/8" of belt deflection at center span when pushed with moderate force with the thumb.
