Which Idler Pulley?

[helty]

Got the annoying squeal, and my car just went over 47k so this weekend is routine maintenance weekend. Gonna go with Synchromax in the 3650, new fuel filter, gatorback belt, and new idler pulley. I found one that has a very slight wobble to it, so Im hoping thats the one I need to change.

2

Drive belt
3

Coolant pump pulley
4
3D673
Power steering pump pulley
5
6316
Crankshaft vibration damper
6
19D784
A/C clutch pulley
7
6B209
Drive belt tensioner
8
19A216
Belt idler pulley
9
19A216
Belt idler pulley

The one in question is #9. Is this the one that tends to go bad and most of you change out? I know that one and the tensioner pulley, #7 are identical, both smooth right? What about #8, the grooved idler? Is that one prone to bearing failure? If so I may just change it while the belt is off. And can someone verify the torque value for the idler? My Haynes says 15-22 ft/lbs, but its not always acccurate. It doesnt even show the #8 pulley in the belt routing diagram.

and this is the replacement I was going to buy for $10.

Go ahead and buy two of them. In your illustration, number 7 and 9 are the same. In your vid, you are wiggling number 9 and the one directly below is 7 but they are the exact same part .. I bought one (the one you're moving) and replaced it ... it still made the noise, just slightly .. so I bought another one and replaced it. Just get two.

on the tensioner i would go ahead and replace the whole assembly. Tensioner will wear out and its better to spend a couple bucks more and get the whole thing than just the pulley.
