Last time I had a squeek it was the alternator bearing.
Use a long screw driver or stethoscope to see if you can narrow where it is coming from.

Run your engine but turn your A/C (if equipped) off. Does the squeak change any if you rev up your engine? Do you have a serpentine belt? Although you have a new belt try suirting water from a sprayer over the pulleys and note if there is any change. A noise from a bad alternator bearing is usually more of a howling noise and it is steady. I suspect that it is your water pump that is going out. If it, the next symptom will be that it will start to leak from the pump drain. Once that happens you better get it replaced because it could overheat and freeze.

yea i thought it might be the bearing also but i sprayed some belt conditior on it and all over all the pulleys and belt and it didnt really help so i dont know if it is the bearing or not. also i still cant seam to narrow where it coming from it sounds like its coming from the pulleys but sometimes it also sounds like its in the back of the engine.

Try squirting a little WD 40 on each bearing, one at a time and see if it stops. That's how I found mine. On my alternator I also squirted the shaft bearings.

i tryed that and it didnt help but i have narrowed that the squeak is coming from the back of the engine. Any idea what it would be?

It's difficult squirting water or lube on a bearing because they're mostly sealed. Are you sure the squeaking noise is not coming from the water pump?

Try taking belt off and spinning pulleys by hand, do not forget the tensioner
