High Pitched Whine increasing with engine RPMs

I've had this noise for a few months and its driving me crazy. it's a high pitched noise which increases with RPM and then i can't hear it past like 3k. Happens always, neutral, in gear, whatever.

WTF is it? Idler pulley? Tensioner pulley? trans?

Just the usual vibrations through the wheel but those have always been there.

Probably a bearing going in one of the aforementioned pulleys or alternator.

Open the hood rev the engine and listen. Use a stethoscope or a rubber tube to listen to each suspected component.

I tried but it's impossible to pinpoint. all i can tell is it's on the left side (if you are facing the car).

So you can hear something with the car not on the road? You can then almost eliminate the transmission. Did you use a mechanics stethoscope?

I can attest to the difficulty of hearing where exactly the noise is coming from. When I was having pulley problems it was really hard to tell where the noise was coming from with all the other components running...

But what you can do, if this noise happens all the time then take your belt off and go for a drive, if the noise is gone then you know for sure it's one of your pulleys. Again, good luck.

^ no i did not use a stethoscope. Just my ears. Yeah the noise is there even with the car not moving and not in gear.

I guess i could just do that and not even drive. cause i would hear it instantly while the car is idling.

When i changed my alternator we found that the bearing had some rust on it (we opened it up). I wonder if some moisture has gotten into my engine bay and fucked shit up.

For me it was the A/C Compressor clutch bearings going bad. Finally got loud enough that the dealer replaced it. Noise gone.

I really hope that's not what the problem is.. I wonder if that'd be under the 70k warranty?. doubt it.

I do hear a cluck sometimes and seems to be louder the first time it engages after a rain. I figured just from some rust forming on the clutch plate. But once running it's more of a CLACK than a clunk. if that makes any sense.

My car started a very faint squeaking noise on my trip

Only does it with ac on

Also only does it going up hill when trans shifts down a gear

I will have dealer look at it

Currently happening at 50 mph +

Can't believe so many things are going wrong on this tsx at only 30 k miles. Thank god for CPO warranty . My previous Hondas and accurate have been bulletproof

so yeah i'm slow and still haven't ordered the part to fix it.

I know exactly what's causing the problem now. It's the idler. But where do I get an OEM one? All i can find is crap aftermarket stuff.

And you want Engine Mounting Bracket, that's got both the auto tensioner and idler pulley there.

I have a 08 Acura TSX and i heard a whining noise and even more when i turned so i replaced the power steering pump. Steering is good now but still makes a whining noise. Especially when i accelerate. Any suggestions?? It sounds like this on this video.

If itís anything like the accord power steering pumps. Itís not the pump. Itís the little o ring that goes on the intake side of the pump. If leaks a tiny bit and caused the whine.

Nope doesnít leak at all. Itís pulling air in which causes the wine but no fluid loss.
