Little whinning noise when vehicle is idle.

[adebuss]

Can any one tell me what can be the problem with my Qx4. There seems to be a little whinng noise in the engine compactment, when the vehicle is in idle. The dealership changed all the three belts. Then they told me is the idler. I changed the idler by the alternator, it doesn't go away. Then I changed the tensioner idler, it doesn't go away. I don't know what else I can do. If you know what the problem is, please let me know asap. I will appreciate if you can get me pictures or diagram for the problem.

is it a whining or squealing noise? does it go away after the car is warmed up? was the car doin this before u changed the belt?

could be that ur new belts r too loose or too tight or u got a bad bearing somewhere
