Whisper

iTrader: (12)

Just like the title, I have a kettle like whistle coming from under the hood and Im guessing its the drivebelt. I was wondering, whats the life of these things? I last replaced it about 2 years ago but I guess it could also be the second smaller accessory belt. Thanks for any help.

I have the whistle too. I always thought it was normal since someone told me their LS1s have the sound too.

It could be a pulley. I had that noise, it turned out it needed a few new pullies. The bearings were shot.

If it rises and falls with your RPM, check your belts.

My AC belt needed replacing.

there are 2 idler pulleys, one for the main belt tensioner and the other for the a/c. Remove them and regrease the bearings. When I took mine out, the bearings were dry. A little moisture like a rainy day and it was chirping like mad.

Try this. If its not this at least they look better than stock.

I have a very slight whistle at idle, I don't hear it at higher RPMs. I also had the chirping sound once when it was raining out and it has never come back. I'll have to grease the bearings some day.

I have a very similar whistling sound that begins once I start the car, however it goes away after only a short time of idling or driving. Weird!

Sounds like it's the A/C

That sounds like the AIR pump. They tend to make a whistle sound after free flowing exhausts are put on the car and will shut on and off almost randomly.
