First, It is not called the idler arm. It is called a pitmen arm it it requires a special puller to remove it from the gear box.
Remove the upper intake and there it is.
Popping noice on my 97 bravada
go to youtube and type in ericthecarguy and change pulley
On my 97 3.5L you have to loosen the bolt (15mm)on the front of the idler (loosen, don't remove) then go underneath and the is a 13mm bolt that adjusts the position of the idler for tension. Loosen this and the idler should loosen up.
Remove the bolts and nuts holding the idler arm to the frame# Raise and safely support the vehicle. # Remove the cotter pin, nut and washer retaining the center link to the idler arm. Discard the cotter pin. # Remove the center link from the idler arm. # Remove the bolts and nuts holding the idler arm to the frame and remove the idler arm. To install: # Install the idler arm to the frame with the bolts and nuts. Tighten to 85-97 ft. lbs. (115-132 Nm). # Place the idler arm and front wheels in the straight-ahead position to maintain steering wheel alignment and prevent bushing damage. # Install the center link nut and washer and tighten to 43-47 ft. lbs. (59-63 Nm). Install a new cotter pin. If, after the nut has been torqued, the nut castellations and stud hole do not align for cotter pin installation, tighten the nut further until the cotter pin can be installed. Never back off the nut.# Lower the vehicle. For more info. and pictures check out Related links below...

you should be able to put a socket wrench in the front of the idler pulley. Push away from the tension of the belt, then remove the belt. MAKE SURE you remember how the belt came off. Loosen the bolts on the pulley, then remove. Install new pulley, then put the belt back on.
If there is a belt there absolutely!
