That first youtube link doesn't work, the second one did.
My best bet would be the power steering pump. Mine started making a similar noise now that the winter months hit. All I did was change out the O-rings for the power steering pump. I bought the set of o-rings, a new PS reservoir cap, and 2 bottles of PS fluid for 20 bucks. Over time the o-rings wear out and don't seal as well as they used to.
The sound would increase with higher RPMs and would still be present at idle. For me it was only the o-rings that needed replacement, it might be the same for you. It's a good place to start, and relatively inexpensive. I think the 2 o-rings alone run like 10 bucks if anything.
I would say it could also be the alternator whining, but we would need more information for that. Are you having any other issues? Any lights dimming or things of that nature?

 

AHH! there is two o-rings! i thought so. So i changed out the one thats right in the middle/bottom of the pump, the one you can see in the video clearly. I didn't touch,change the one thats on the very top top(The line runs across the entire engine that line), i had no idea that top one had an O-ring. The only one anyone mentions is the on thats on the middlish/bottom that has a hose connecting to the reservoir. Ill try and find that P/N for the top O-ring tonight and order it since they are always cheap.

but I DID do the middlish/bottom one.

 

Take a screw driver or something wooden and hold it to your ear and against the pump body. Then rest it on something else like the alternator body and even the tensioner body. You will hear which is making the noise. I have a mechanics stethoscope to do this, but most anything will do. It really makes bearing or pump noise stand out.

Don't sticky your ear on the pump as your face will be ripped apart by the pulley and belt.
Safety last

 

Okay lets say I go grab a long flathead and still it against the tensioner or pump ect what is the noise I would be hearing if you couldnt describe it?(For example injectors make a kind of clicking noise lol) what would be the noise of the problem if one does exist?

 

I think most think you're shitting them when you try the ear trick. The stethoscope they sell really doesn't do much better. Might be worth doing to get a good sense of what normal sounds like, but when you find it, it's pretty obvious.

 

So heres an update, i Know its been 2-3 months but time has been an issue, anyways the pump continued to make this whine(It literally is pitchy and whiny like a SC), so I went out and got a used power steering pump(LKQ in california, came off a care THAT DID NOT HAVE THIS WHINE NOISE), car had very low miles so pump is very believed to be perfectly fine, I did another PS flush(3 more bottles), until i to my knowledge the fluid was clean and than began to bleed the system until I did not notice anymore bubbles.

the noise still continues to happen, to best describe it, its almost non-existence when the car first starts up, and the more warm the car gets the louder it gets, it gets louder with the RPM's and if i turn the wheel while rev'ing the noise also gets louder.

I'm finding it very hard to believe that both pumps are bad and now thinking this is something else that relates to the PS pump, I have read a few places on forums that our reservoirs have a screen at the bottom of them that get clogged around my milage and it causes the fluid to not be able to circulate properly making the pump "Starve" for fluid. Can anyone confirm this? I really don't want to remove and replace mine and make an absolute mess if this is incorrect info. any incite at all would be awesome! thanks,

 

I just fixed a Chrysler van that needed a clean screen as it wouldn't stop whinning. Quiet until it re-plugged in a few miles. I had to get a new reservoir as it was molded in.

 

SO thought I would update this post as there is absolutely zero help on the internet with this issue. So After a year+ of this whine and it STILL not being away I thought I would update everything I have done with STILL no resolution. As of right now I have done BOTH O rings(The upper and lower that always go bad), I have tried the the OEM one and the newer one people recommend no help at ll. I sucked it up and Ordered a new reservoir(A1 Cardone) and PS pump(Ac-delco since all reviews were so popular and oem is absolute rape of a price.), I have flushed the absolute shit of the system with OEM Acura fluid. I have used a total of around 15 bottles So its safe to say the fluid is clean. I have put the car on jack stands and cycled the wheels left to right and right to left not even kidding 500+ times(even have this on video with my camera into the reservoir so I can see the bubbles still coming up). I have done this process with the car completely off and the car running both 250+ full cycles. The car still whines so loud and I can't get it away and makes the car so fucking miserable to drive. I have tried EVERYTHING, if anyone can give some insight on this it would be really great.

Only thing I can possibly think of is there is a leak somewhere in the system but its so small I cant find it anywhere and everywhere I call shops and all tell me they don't have a system to find a leak on a PS system

 

At what point might you think it's not the P/S. Would you think the noise would follow a new pump? Your leak detection would be needing to fill, or drips from the bottom.

 

I wish I could show you in person but its very very obvious its the pump. This is what is weird, I have ONLY used oem fluid and nothing else and havent introduced anything else. I just did another lock to lock cycle and checked the fluid after and it looks terrible. Like contaminated, almost like chocolate milk with dust/dirt specs in it if that makes any sense(If you have Instagram and don't mind adding mine is Ej1Maurice I can send pictures much easier on there). Now I don't know how true this is, but I was told introducing air into the system can "Contaminate" the fluid and give it this milky dirty look(There is no damn way there is dirt or old fluid in there when I say I flushed this I mean I flushed it so damn much I've wasted 100$+ of fluid by far). Now if this is true I have no problem doing one last flush to rude that option away but I have a feeling there is just something else wrong or I missed/did a step wrong some how.

 

I have no instagram, so I believe your words. Don't worry about the fluid for now, First go left right left about 40 times. Or first look at every bit of hose and rack for a leak. Even out by the tires see if the arms are coated in oil, and look for dripping. A leak will leak. If it's not leaking, stop entering new fluid, contamination is the least problem--I've never changed fluid on any of my cars ever. Not great advice, but outside that van, I've never really had ps problems. Look for leak, crank the wheel more and report back

 

With the car on or off? Obvious car on jack stands and power steering cap off but with the car running or the car with the engine off?

 

Man. I didn't know it was that unbearable. Whenever I replaced my high pressure hose due to leaking, I did the several turns lock-to-lock with the car on and cap off and while the car was on the ground (level). I know this is bad for the tires generally but I think I had them on pieces of cardboard to help lessen the coefficient of friction, but I didn't have any air in the system. Idk man

Maybe you should check the line/hose flare nuts are tight?

If the pressure control valve is blocked up maybe this would happen? Shoot, anything restricting it might make this sound I guess

Are you actually leaking/losing fluid though?

 

Is it possible it’s the ac compressor? Mine was starting to chirp, so I had it replaced before it burned out.

 

Hey! Just replaced my whole system and have this issue with a new ps pump. Did you ever figure this out?
