I don't believe there is an idler pulley on that model, just a tensioner pulley
Are you talking about the "idler pulley"? They are quite simple to change. Loosen the serpentine belt by using a socket on the center of the tensioner pulley, slide the belt off the idler pulley, use a socket to pull the center bolt of the idler pulley and replace the pulley with a new one.
The idler pulley has nothing to do with the brakes. If the idler pulley is bad it could throw or break a belt, and then your engine will stop.
In an Inline 6 Jeep engine, the idler pulley is located to the right of the A/C pulley. It is a smooth pulley, not a grooved one.
If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley. Pry the idler back and remove the belt.If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley.

Remove the belt, then remove the bolt holding in the idler pulley.
The idler pulley is between the alternator and the A/C compressor.
Remove the old, damaged idler pulley and replace it with a new one.
Replace the tensioner assembly as one piece.
== == it is a free pulley that works as a tensioner on any belt bolted to hold or spring loaded An idler pulley usually tensions a belt.. eg supercharger belt is kept taut by its respective idler pulley
Is it serious if my car idler is making a noise?
This is real easy on the 3.8 L engine Whether its front wheel drive or rear wheel drive all you have to do is locate your idler pulley and use a wrench that is the size of the nut on the idler pulley and move the idler pulley just enough to pull the belt off. Be careful to release the tention on the idler pulley slow it is under spring pressure. Use schematic under hood to put on new belt. This will take about 5 minutes to complete. Hope this helps.
