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?

I thought you already posted this

^ I think i did but i forgot all the respones or they were wrong.

I dont know for sure WTF it is. Google leads me to beleive its one of the pulleys going bad.

Any vibration?

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.

^ I already replaced the alternator

I guess i'll order the two pulleys.

Yeah, go whine somewhere else..

get it... lol

oooh 2 funny 4 me

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.

Just try what I suggested and move from there

so what was the result?

I didn't get a chance to do it yet.
This fuckin' day... :whyme: anyways it's too cold.

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.

They only replaced the clutch. Not the compressor.

hmm ok. so maybe i'll just need a clutch bearing?...

anyways i'm getting ahead of myself i still have to take off the belt and see if the noise is gone....

Yeah go do it already. It takes like 10 min

Did u heard a loud clunk also from the clutch compressor also ? Mine is a bit loud from outside the car , not so much from inside ! I wonder if this is normal !
sorry to hack the thread ! Thanks in advance

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.

Alright, is this a normal clanky noise ...lol ?

Clanky, no. But a sold clunk yes.

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.

This ^^ +1
