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 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.

Is it serious if my car idler is making a noise?

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.

The A/C belt uses an idler pulley accessed from under the car. That lock nut is in the center of the pulley, and the ajustment bolt is located on the side of the pulley.

in front of motor under the belt tenser

I don't believe there is an idler pulley on that model, just a tensioner pulley

The idler pulley is located just under the A/C compressor. There is a bolts in the middle of the pulley that needs to be removed and the idler pulley can be removed. Sometimes these bolts stick and my need to be pryed off. You may also want to removed the radiator fans cow to give you some extra room.

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).

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

Get a manual on your car and it will give you the procedure.

The A/C compressor is located on the bottom of passenger side of the engine. It is the unit between the crankshaft pulley and the idler pulley. It is driven by the serpentine accessory belt.

User Avatar

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.

If your car has a serpentine belt it will have a tensioner pulley. A tensioner pulley is easy to spot. All of your bolt on accessories i.e. water pump, alternator, a/c compressor etc. will have a pulley to run each one. There will be 2 other types of pulleys, a idler pulley and a tensioner. The idler pulley will be a single stationary pulley with a bolt going through the middle and the tensioner pulley will be on a spring loaded piviot.

Take the belt off, un-bolt the idler pulley, bolt the new pulley on, and finally put the belt back on and Viola!!

User Avatar

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.

User Avatar

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.

User Avatar

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.

i dont really know-but to find out just look it up on google!
