The belts generally don't make a whining noise. They squeak. The whine is probably the tensioner or the alternator. Listen closely you should be able to tell where the noise is coming from. You can also take off the belt and roll each component and feel for bearing crunching.
if the noise is a high pitched squealing noise, the belt is slipping....if the noise is a whine or growling noise, the pump is low on fluid or the pump is bad
If the noise sounds like a power steering whine it could be caused by the A/C compressor clutch bearing or the belt idler pulley.
If the power steering pump is making a whiny noise on a Pontiac Grand Prix, the way to tell if this noise is from the pump or another source is to turn the steering wheel. If it turns hard, the problem might be with the pump. If the belt quiets down after a drop or two of dish soap is placed on the belt, then it was just the belt causing the noise.
belt tension too high.
Possibly and it can be the drive belt making a noise. It you hear a whine it is likely the alternator bearings are shot. You can remove the alternator and have it tested at most auto parts stores, after you make sure the belt is good.
if your not using the belt then when the sound starts just push the realeas button on the seatbelt and it will stop
It sounds like the power steering pump to me. my guess would be that you have a bad or loose belt ( sliping ) or you have a pully that is gonna either come flying off or lock up completely....neither is good. also a tight belt can cause the whine if it is tight the whine could be coming from the pulley bearings (alternator etc)
If the whine happens when starting to move forwards, and then stops once the vehicle is moving, it could be caused by a loose fan belt. If so, tighten the fan belt, or replace the worn belt.
Spray hairspray on the belt if it is making the noise or replace the belt or the pulley if its making the noise.
It depends on the noise. If it is a squealing noise it is probably a loose belt and needs to be replaced. Check the back of the belt if it is "glazed" meaning slippery and shiny then replace the belt.
loose alternator belt
It's probably the belt slipping. Check for belt tension. When an engine first starts the alternator works harder to recharge the battery. During that time, the alternator is harder to turn and if the belt isn't tight enough there can be some slipping between the belt and the pulley.
