To apply tension
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.
To adjust the idler pulley on a Dodge Ram 1500, first, locate the idler pulley in the engine bay. Use a wrench or ratchet to relieve tension on the serpentine belt by turning the tensioner pulley counterclockwise. Once the belt is loose, you can either replace the idler pulley if it's worn or adjust its position if applicable. After making adjustments or replacements, ensure the belt is properly reinstalled and tensioned before starting the engine.
== == 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
No, the tensioner pulley and the idler pulley are not the same, although they serve similar functions in a vehicle's serpentine belt system. The tensioner pulley is designed to maintain the proper tension on the belt, while the idler pulley guides the belt and helps maintain its path. In a 1998 Chevy Cavalier, the tensioner pulley is adjustable to compensate for belt wear, whereas the idler pulley is typically fixed.
