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.

The relays have nothing to do with the whining noise, they just complete the circuit and make things work. The whining noise is the fuel pump and that is a common problem with Chevy That noise will not hurt anything, but I would change the fuel filter and that may quite the pump a little. A stoped up fuel filter will burn a fuel pump up.

Can a weak battery cause the alternator to make a loud whining noise?

I would say probably not, the reason your battery is weak is I reckon due to a fault with your alternator. It is obviously not producing sufficient power (electricity ) to keep the battery charged. The whining noise is probably caused by worn-out bearings. A replacement or re-conditioned alternator should cure the problem .

Why would your car still be whining after the power steering pump is replaced?

One source of whining could be many things but the first that comes to my mind is the Alternator. The CV joints could possibly make this noise too but I would personally consult a mechanic about this. any motor attached to the engine could be a cause but I would take it to a mechanic: alternator, compressor, water pump, etc.
