Doing a bit of looking around I found the following:
Part Number Y54414 (AP4291235) replaces Y54414, R0609504, 14218926, R0609504, 54414
I don't believe there is an idler pulley on that model, just a tensioner pulley
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.

The idler pulley is between the alternator and the A/C compressor.
Remove the belt, then remove the bolt holding in the idler pulley.
Replace the tensioner assembly as one piece.
Remove the old, damaged idler pulley and replace it with a new one.
== == 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?
Most idler pulley's are near the top and usually quite easy to get to. Press on the belt somewhere, enough to deflect it a couple inches and watch to see which pully is mounted on a tension spring. That is the idler pulley.
the idler pully is the top center that that spins freely and is connected to the block.
