My whine sounded like the power steering pump ,but the steering was fine. I would turn the wheel and the sound never chaged found out it was the idle pulley next to the power steering pump.

What is making this 08 caliber 2.0L sxt cvt have a High pitched whining sound at idle and driving?


Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one

Can't get rid of Power Steering noise on my 2001 Oldsmobile Silhouette


You haven't described the noise or whether the noise increases when the pump is under load, or perhaps that is the only time it makes a noise?

As you undoubtedly know some noise is natural when a fluid is being forced through hoses and orifices under great pressure and some systems are noisier than others, especially when the steering is on full lock and all the surplus pressure is diverted through the relief valve.

Perhaps there is an inherent fault that is causing the fluid to become aerated or perhaps it is something more basic and the drive pulley alignment is off.
Perhaps it is a matter of poor routing of hoses and pipes transmitting normal noise into the body and amplifying it.

I believe there are additives available that can help lessen some of the noises of complaining oil.

What might cause a high pitch (alto) engine whine in a Honda CRV 2007?


Power steering pump. Fluid is either low or the pump is wearing out.

High Pitched Whine


A high pitched whine like that indicates a bad bearing. Water pump, power steering pump, accessory belt slipping, alternator bearing, or in the worst case scenerio, Transmission pump.

Engine making whining noise


There are a couple of things to check. If your power steering pump is low on fluid, or a bad bearing is in the Alternator, they will whine. The PCV valve or any hole in the Vacuum lines will whine as RPM is increased. Even having the Air filter box not fully seated will make a whining noise.

Now both automatic and manual transmissions can whine as RPM is increased. Check fluid for each.

Serpetine belt and pulleys-can make noise.

Sometimes you can shift into neutral at any speed and the engine rpm will drop almost instantly as the car rolls at speed. If the problem disappears as soon as the rpm drops, then an engine part probably is the reason.

My 1991 subaru 2.5 legacy boxer sounds like the power steering is out of oil when you start car in th mornings, but ok once car has been run ,


Your Pump is getting worn, as it expands the noise goes away. You can try and Empty the Power Steering Pump of its fluid and put new in and there is a chance it will go away but if it does not, you are looking at replacing the Pump.

Preventive Maintenance goes a long way, the same thing with the brakes, Engine, Transmission, ect.. They all require changing the fluid to prolong the life of the components.

Whining when i press gas


normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.
