Finally had a moment to replace the belt, still hear the squeak but I may not have pin pointed where the noise was coming from initially.

I've noticed now that it's only making the noise when the engine is under load. So the sound occurs at idle when the AC clutch engages and I rev the engine as well as when the AC is off and the car begins to move from a stop.

I can get the squeak every time if I stand on the brake and engage the clutch (it's a manual). As the engine starts to lug it'll produce a high pitch chirping noise.

There is no squeak when the engine is at idle with the AC off - but the squeak doesn't seem to be coming from that side of the engine. It's closer to the mid to passenger side.

I'm about to just start replacing idler pulleys to see if that'll resolve it.
