If it comes and goes, maybe it's something load dependent. Does it happen more often at night with all the lights on? How about while the steering wheel is turned? With A/C compressor running (on some vehicles, Defog will run the compressor automatically)?

it makes sound even at night or day...
it happens either the ac, heater is on or off..
it happens when the steering is turned or not....
i'm really frustrated with this...any suggestion..?

i dont get how to drive with the belt off...what do you mean by that?

Doesn't the A/C compressor have its own separate belt? You can take that belt off and still drive it. Also, if the noise were more of a squeak rather than squeal, it could be coming from the crankshaft balancer. I don't know, it's just a thought.

You know there is a cheaper way to find the squeal if it is a belt.I have used a little dap of Dielectric Grease.Put a little dab on the outer surface,and a little dap on the inner surface of both belts.DON'T put a lot on the belts.I have done this for many years because alot of these belts do dry out,and get a very shiney surface and a little of that grease cuts the noise out 99% of the time.

Something else to consider is the tensioner pulley, if it is weak even a new belt will squeal like a banshee, with that many miles I'd replace the tensioner...
