What would cause a loud whining noise in a 2001 Saturn SC1?

timing belt

AnswerI wouldn't think it would be the timing belt. In fact I thought (although I might be wrong) that most Saturns have steel timing chains.

I would suspect the noise is either the power steering pump or one of the serpentine belt tensioners.

In fact I had a loud whining in my 2000 Saturn and it was the bearing in the serpentine belt tensioner. We replaced it ourselves, it was not too bad of a job.

AnswerIf the noise sounds like a jet engine turbine, it's probably the alternator getting ready to self-destruct. Check it by running the car and turning accessories (headlights,radio,wipers,etc.)on in sucession. If the noise gets louder with each accessory you add, think alternator. Answer(Former Saturn Service technician) I would say that if it't a high pitched whine that varies with engine speed, it is most likely the alternator. A lower pitched "whine" or "growling" might be the serp. belt Idler Pulley. In my experience, I never saw or heard of the tensioner pulley bearing faliing so most likely rule that out. A bad tensioner usually makes a "rattling" type sound and is accompanied with belt "squeal" AnswerMy loud whining noise in my 97 Saturn SL2 WAS my Idler Pulley! I replaced it for around $23 at O'Reilly Auto Parts, but the original owner said that it was making that noise when she bought it brand new from Memphis Saturn, so apparently this was a defect from the factory. Anyhow, it is now fixed and I can drive around without going crazy!


I have a 96 sc2 it wined like it was a power steering pump but it was the idler pulley. To find out if that is the issue is to grab all the pulleys one at a time and see if they are tight or not. Good luck it only cost $20 dollars for the idler puolly and that fixed my problem.

yes but why would you leave it loose?

Yes, the bearing in that pulley may be going bad.

ON the 2006 impala that whining noise is actually the electronics when you accelerate. Its more or less electronic pulses/signals My 06 Impala is the same.

Possible its time to change those brake pads out. The whining noise is possibly the metal grinding to your rotor, which would cause your wheel to shake. Consider getting those rotors turned as well.
