One of my idler pulleys went bad already, the bearing is sticking and causing belt squeal and squeaking at startup. Its the lower left idler on the bracket, I believe it's the 4FH016-150 IDLER PULLEY, 6-RIB SMOOTH 3" FLANGED.

Can anyone confirm that part number for me so I can order a new one?

Thanks in advance!

try loosening the bolt on the squealing pulley and see if the noise goes away. I had the same issue awhile back and I played with the tightening of the bolt and the noise went away. Or it could be bc your belt is too loose and it squeals.

 

The pulley bearings are shot, it has to be replaced.

 

Thats what the install manual says it is..Its the only idler on the mounting plate

 

Actually, there's three. Two ribbed, one non ribbed. I need the non ribbed one, just wanted to make sure I had the part number correct.

 

Left the word smoothed off

 

Non Rib Idler is Dayco 89003
6 Rib Idler is Dayco 89009

You can get these at just about any autoparts. $23-$25

 

Awesome! Found one here ...

How were you able to isolate the problem to this pulley?

 

One of the three was squeaking, I took them all off and checked the bearings. It was pretty obvious which one was bad.

And Autozone has replacements as well. They're dayco pulleys, but have different part numbers and are packaged as their in house brand Duralast. I basically went behind the counter and picked through their box of pulleys until I found the correct one.

 

I've lately been getting s squeal on start up but seems to go away after a few minutes. Noise seems to be coming from the GTM pulley or in this general area..I'll wait and see if it gets worse before taking any action..

 

im kinda having a problem like this its not the belt slipping from a cold start up though i know when that happens but it seems like when my car is cold it has a pulsing squeel that really sounds like a bad bearing in one of the pullies but it seems to go away after the car is fully warmed up.. im not sure if it really goes away or if i just cant hear it because of the drop in idle speed when warm..

 

You both described my exact problem. The belt would initially squeal since the pulley would stick, then once it started spinning it would squeak for a few seconds and then sound fine. Problem is that your pulley bearing is basically sticking (frozen) and the engine spinning breaks it loose eventually.

 

Not sure if it's the belt screaming or the pulley bearings breaking free and squealing until they start rotating..

 

Take the belt off, spin the pulley by hand and see how it feels in comparison to the others. It should spin freely and not feel notchy or stuck. Doing that check would only take you about 15 minutes.
