chirping/squeaking from the belt drive

[xsx450]

I am trying to diagnose a higher pitched noise that is coming from the front of the engine.

This is while it idles, and it mainly bugs me because it just doesn't make the car sound as nice as it should.

Sound is intermittent, usually worse when cold. Sounds like something needs to be "Greased" (Squeaky wheel gets the grease).

I definitely have a small amount of alternator whine, which is similar in noise, but at least that is consistent and doest sound like something is worn out.

I am guessing it would be one of the tensioners, but as far as I can tell there are 2 or 3.



I cant tell if these are two different tensioners, or the same tensioner. "4" Doesnt have a part number associated

I am sure replacing ALL the tensioners/belts would be my best bet, but these things arent cheap.

has anyone had any experience with a slightly squeaky belt drive, and its fix?

I dont see these things under maintenance, people just say do the belt. But I have seen many tensioners/rollers/guides/bearings whatever you call it create noise in the past.
