Idler pulley takes up the extra slack from the serpentine belt.Serpentine belt, drives accesories from the crankshaft ie., usually,. water pump, Power Steering pump, alternator,air conditioner compressor. Older vehicles had separate belts for driving these componants and each had it's own adjustment location which was done manually,[which is why belts would schreech when loose] most of the newer stuff has idler pulleys which are self adjusting [spring loaded]the bad part is serpentine belts can be pricey and the bearing in the idler pulley can tend to wear out and the whole unit has to be replaced.

The belt tensioner actually loads the tension on the belt The idler pulley on a Saturn actually just maintains a balance of pressure on the pulleys. It runs between the P/S puimp and A/C compressor on vehicles that have p/s and a/c. The belt from the dealers is only $35 Canadian That's not expensive at all
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.
Remove the belt, then remove the bolt holding in the idler pulley.
The idler pulley is between the alternator and the A/C compressor.
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 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?
the idler 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 pully is the top center that that spins freely and is connected to the block.
Probably not usually. For an idler pulley to put so much drag on the belt system that it stalls the engine, it would break or throw the belt altogether before the engine could actually stall.
Take the belt off, un-bolt the idler pulley, bolt the new pulley on, and finally put the belt back on and Viola!!
To apply tension
The Answer is no.
The idler pulley is mounted on a plate that needs to be removed. In order to remove the plate with the idler pulley, you must remove the engine mount to get out the idler pulley. To remove the engine mount, you need to jack-up the engine from the bottom of the oil pan (Note: place a piece of wood plank between the bottom of the oil pan and the jack).

If the idler pulley is frozen, it is high time to replace the timing belt and the idler. And while that job is being done, consider replacing the water pump and thermostat.
pretty much-the 2 get confused all the time. Technically a tensioner is an assembly with a spring and an idler is a fixed pulley-most newer cars have both.
Changing an Idler Arm on a '99 Saturn is MIGHTY difficult, especially since they don't have one. The '99 Saturn uses a Rack and Pinion steering system, and as such does not have an idler arm.
An idler pulley is a pulley that does not drive and is not connected to any device that is driven. It serves to either tension a belt or to route a belt to clear an obstacle.
