Another pressing question.

When I start my Z28 in the morning, I'm hearing a really loud "squeeky wheel"(sound speeds up when I get on the gas) noise, that's loud enough to be easily heard over the rumble of the engine. It only subsides twenty minutes or so after the car warms up, and it slightly intensifies if I turn on the AC.

Anyone have any idea what it might be? I don't have any warning lights coming up, the car's running strong as ever, and all the gauges are showing normal.

I'd give anything to get it to stop, it didn't use to do this, but somehow recently has acquired it. And it's not the belts, both belts are new. It's embarrassing to ride past the apartment complex bus stop with this loud squeaking going on, making my LS1 sound like a 1987 Buick on a thirty degree winter morning.

 

It deffinatly sounds like the serpintine belt, if you just got them then i suggest getting some lithium grease or some kind of grease of some sort and spray a lil on the pulleys and belt, it should stop. Other then that something could be loose.

 

Since yours is a 99, I'd be willing to bet it is your idler pulley on its way out.

Do a search with idler pulley in this section and you'll come up with lots of info.

i second the pulley problem.

i would swap to a new belt first...nice cheap and easy possibleremedy

pop the hood and see if you can isolate the sound source.
another thought would be your air pump for emmissions, it's located behind the driver side headlight...listen for it, you'd be able to tell if that's where it's coming from

 

Sounds good. Also, the "idler pulley", is that something easily replaced? I am admittedly not very good mechanically as yet. How much would such a part cost?

However, to respond about the belts, both of them are brand new, roughly a week old. I don't think swapping them would do anything.

 

Idler Pulley::
Replaced mine and Gm part was $48 for complete pulley assy.
Smart me, I bought a bearing for the pulley and it cost $46.
I had to have a friend press out the old bearing and press in the new one.
If I had it to do over would just buy the one from GM!
Just my $.02 worth!
This correct my squealing and was a simple job, about 15-30 min.

 

should just be a couple bolts.

the hardest part will probably be getting the belt routed correctly over the maze of pulleys and tension wheels

 

Well, that's the easy part. My dad and I changed the belts in roughly seven minutes. I guess I just need the part. I wonder if it's covered by my warranty? I paid for an extended bumper-to-bumper warranty when I bought the car used through my credit union. Hmmmm...might be worth checking out.
