Squeaking/Whining Belt?? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

mbrusco103 · 10-17-2010, 09:33 PM

The past few days ive been hearing a squeaking sound when my camaro is running but i didn't hear it while driving around. today as i was driving home from a car show it got really loud when i was driving

i popped the hood when i got home and i noticed the the thinner belt on the left side is partially off the pulley by 1 rib. I tried to adjust the pulley by loosening the bolt on the side but it didn't do anything then i tightened it up a little and it squeaks less but still on 3000+ rpms it still squeaks a lot.
Anyone know whats going on, if its just the belt or is something else out of line?
Going to be calling the service department tomorrow hope its nothing major.

I have a slight Whine.. sounds like its coming from the belt, but its been there since day onc.. haven't had a issue with the car, so I've just ignored it.

I also had a slight whining but I thought it was normal .. how many miles do you have on the car I have about 3200 .. I'm currently at the service department waiting for a tech to check it out

mbrusco103 · 10-18-2010, 03:42 PM

In case anyone wants to know.. they were all stunned to see that one of the belts was off the pulley and even more stunned to find out that theres no tensioner to adjust it. they ordered a new belt and will install either tomorrow or wednesday

CyberDan · 10-18-2010, 05:46 PM

I've got 2800 miles on mine... But like I said, it been whining like that since day one... Only at idle.

No tensioner... What?

mbrusco103 · 10-19-2010, 06:22 PM

yeah thats how mine was to but i thought a little bit of whine was normal.. yup thats right theres not tensioner on the AC belt. the service department ordered one and im bringing my car in tomorrow

CyberDan · 10-19-2010, 11:11 PM

Any pics of what the tensioner looks like and the location?

mbrusco103 · 10-20-2010, 12:58 AM

i typed that last post wrong.. i meant that they ordered a new belt.. apparently it just stretches over the pulley with some special tool and there is no tensioner involved.

mbrusco103 · 10-20-2010, 02:14 PM

just got back from the service department and they changed the belt. everything is fine now that solved my problem hopefully it doesn't happen again.

CyberDan · 10-20-2010, 05:46 PM

So it was just a bad belt?

mbrusco103 · 10-20-2010, 06:51 PM

yeah basically it was a bad belt but the reason it was bad is because it wasn't installed properly from the factory the tech said it was off by 1 rib and that only happens if it was not centered to begin with.

CyberDan · 10-20-2010, 07:55 PM

Ahhh... Well I gotta inspect mine then. Thanks for the updates

afireinside · 10-21-2010, 08:10 AM

Man I have that too...... I have been wondering what the deal was

mbrusco103 · 10-21-2010, 09:31 AM

yeah you should pop the hood and look at the AC belt because on mine you could see that it is clearly off the pulley by 1 rib .. it's the smaller belt behind the main belt on the passenger side

Lycanine · 04-01-2011, 01:39 PM

My car just started doing this last night! Thanks for posting your info, I'm going to go check mine now...

newmoon · 04-01-2011, 02:11 PM

I get a little belt or pulley whine from my car for the first 5-10 mins especially if I haven't had a chance to start it in a few days. I took a quick peek but really diod not notice anything, I will look harder at the 2nd belt.

I seem to have the same problem

For a long time now my car has had a noise when idle at cold engine temps and a little bit when warm.
The sound/noise is less when the engine is warm, but it is still there.
The sound/noise sounds to me like a bearing on one of the pulleys grinding, or like a belt slipping.
I took my car to my dealer last year and the service manager rode in the car while I drove.
Then when we returned to the dealership he heard the noise from belt(s)/pulley,
but said he could not determine where it was coming from.
He said I shouldn't worry about it unless it gets louder.
Well it's another season with the car now out of storage, and the sound/noise is still there.
It doesn't seem to be any worse than before, but you can definitely hear it.
It is kind of embarrassing when I am showing off my car to others because everybody hears it as the car idles.
At idle the engine should run quietly, but mine has always had this bearing grind or pulley squeal/grind noise.
I will more than likely replace the stock exhaust soon and that should give me something else to listen to besides my engine winning/grinding noise.
I would rather fix the noise, and change my exhaust for other reasons.

Anybody else having this problem?
Anybody have any suggestions about what it is or what I should do?

Its the AC belt same problem as mine and it will most likely get worse. Demand that the dealership fixes it because it shouldn't be like that.

joe h · 04-02-2011, 03:06 PM

If you are 90% sure it is coming from the ac belt and your dealer won't budge on replacing it under warranty, just take a knife to it and buy an aftermarket at napa and sound will disappear.

camaro5 · 04-02-2011, 03:42 PM

Probably is an alignment problem. They can shim the component to acheive proper alignment.

chandler · 04-02-2011, 10:11 PM

All your posts sound like my car. Dealer said he could not hear it and when I picked the car up it was quiet. When I got home, pulling in the garage, it was back.

The noise is hard to pinpoint but I will look at my belts.

4/4/11 Looked at my belts and they are seated in the pulleys properly. Even with the engine running, no belt misalignment, pulley wobble, etc. Naturally my "belt squeal/bearing whine" has been quiet for the past couple of days so will have to wait and see...at about 5300 miles.

4/5/11 Noticed the noise is back as I was idling in the garage...frustrating.

White&Nerdy · 04-04-2011, 02:10 PM

My belt was whining from the minute you started the engine and would never go away no matter how warm the engine got. It sounded more like an old a/c clutch pulley, but I took it in and they found that the Harmonic Balancer had loosened up causing both the belts to wear. Service department had to get the HB sent in. Once received they replaced it and both of the belts under warranty. Car has around 6k on it. A little concerning!!

newmoon · 04-13-2011, 04:41 PM

Just checked my a/c belt and sure enough it is off by one groove at the crank pulley. I guess I will bring it in for warranty work. This should be interesting as I have a aftermarket CAI, HF Cats, and drag radials lets see if they give me an issue with warranty.

newmoon, let us know how you fair with your dealership. Thank you!

My AC belt was off by one rib and was making noise. The belt started to fray the dealer replaced it no questions asked, no more noise.
