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, altenator,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. L. Keedy It controls the routing of the belt. The amount of contact betwen a pulley and the belt determines how much power will be available for the alternator, power steering pump or water pump. One of the idler pulleys is mounted on an arm that is spring loaded to keep force on the pulley. It's called a tensioner pulley or belt tensioner. That makes sure the belt is tight and able to transfer power properly.
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. Pry the idler back and remove the belt.
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.
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.
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on
No. The idler pulley only maintains tension on the serpentine belt. A faulty idler pulley can cause noise and a loose tensioner arm can cause belt slipping but other than having a similar name, it has nothing in common with engine idling.
