Default Re: T1N 2.7 Serpentine belt install... my way.

Smooth running of the belt is what should be observed. If you noticed wobble or other tracking issues it can be signs of tensioner, idler, or other issues.

If belt wobble isn't traced to other components, it may be a sign of impending HB failure.

From the NCV3 section.

Wish I would have looked at this before pulling the old belt off.

A thought if on the road and the anti-flutter pulley is your problem. WON'T WORK!!

I went out and noticed that there is quite an angle created by the anti-flutter pulley.

The belt system should run without that anti-flutter pulley. Keeping to reasonable speeds it should work for a reasonable length of time.

I have not tried running without the pulley. If anyone decides to try emergency operation without that idler in place you should first start the engine and observe how the belt is tracking. If ok at idle try revving a bit to see how it does. My bet is that with light throttle use it will be good enough to get down the road to replacement parts or service.
