newb drive belt service question

Okay.. my AC belt is loose/bad.. I want to first try tightening it..

I believe I just need to tighten the tension on the Idle Pulley to accomplish this.

On this diagram, it shows a bracket + bolt behind the pulley... is this the bolt I would turn to increase the tension?

Is that all there is to it? Looks like I might need to remove the engine skid plate to reach to this bolt.

What's the deal with those recommended troque settings? Do I need a wrench that can be set for a particular torque setting?

THanks.

 

You got it an yes you need to remove the skid plate to do this.and the torque thing is no big deal just don't go to crazy

 

Hmm is there enough clearance on a TRD 4x4 to do the belt switch without lifting? I just pushed on the belt and it seems pretty tight..
