Serpentine Belt Problem. Please Help.

["350Vortec"]

Well, Im coming to you guys for help now because the A holes at my local auto stores refuse to come out and look at my truck themselves. Must be the whole, Im a teenager so no one help me out deal. Hate that sh**

Anyway, This morning i started my truck after it had been sitting in the gym parking lot, And i heard a...not squeal, but almost like when you get rocks in a skatenoard bearing or something to that effect. So i popped open the hood and the sound is def coming from the belt or wheel(s). It seems to be coming mostly from the wheel thats closest to the hood and the computer. Any ideas? I sprayed it to see if it went away and it actually did. And still seems to be fine right now.

Maybe the metal on my belt wore through? It sounds like metal to metal contact.

If it is just a squeal, then you are probably looking at a new belt. Belts dry out and will make noise on you. If it is driver side, top, that is the A/C compressor. Turn your A/C on and see if you hear the noise. Then turn it off and see if it goes away.

Merhaps if you took a picture and circled the pulley you feel the sound is coming from?

This one here

I believe that is the AC compressor. There should be a sticker or two in that tells you how to route the belt and what each component is.

Thats the A/C.

Check belt for cracks!

AC compressor, bearings do out out. It happened to me.

["350Vortec"]

Thanks alot guys!

Remove the belt and give everything a spin by hand. You should be able to tell what is not turning free. I have found, the rear bearing in the alternators to be the weakest link, on average. :)

DALE! :party33:

Hows that wastegate situation/problem going?

[bowtiefreak]

In addition to the alternator, the tensioner is the next thing to check.

[blueflamed03]

yep, sounds like AC compressor.

The pulsing control solenoids for the wastegates got put on hold to make way for other projects.

Last summer was consumed with building the new garage to accommodate the hoist, plus adding heat and air conditioning. Over the winter, I spent free time, working on more mods for the Camaro. I hope to finalize those mods on the dyno this weekend.

Then I hope to be able to get back to cranking up the boost on the Tahoe. Just doesn’t seem to be enough hours in the day. :)

Like others said. If it is definately coming from where you circled on your picture, then you are more than likely looking at A/C compressor bearings, maybe A/C clutch.

I would definately take TwinTT's advice and remove the belt, spin the pulleys by hand and see if you can pinpoint, may save yourself several hundred dollars if it isn't the A/C.

Thanks so much guys, I really appreciate it. Is this something i can drive around for a while without any serious damage? Because i really cant afford another couple hundred.

[blueflamed03]

until a bearing locks up, not good...

[bowtiefreak]

If it is the AC you might be able to route a shorter belt around it

had the same problem .... a/c compressor .... cant rte a shorter belt cuz theres no pulley under it .... the have a a/c compressor by-pass bracket at auto zone for like $35.... just take the comptessor of and replace with bracket until u can afford a new compessor ....or hit da junk yard for a used one which would be around $35 -$40 dollars and if the used one is good thats a bonus , if it's not at least you won't have that annoying ass grinding sound

[BattelWagün]

I'd just route a shorter belt around it, you'll be fine until you repair it. Just wont have A/C!!

And I definitely know what you mean by the "hey a young kid lets jerk him around" thing:emotions122:.... (i'm actually 17, accidentally picked 84 when i registered...)

[04SS99Denali]

wheels? you mean idlers/tensioners. in your picture your looking at the ac compressor. when i had my OBS the compressor was shot to shit and it was making the ugliest squeal in the world. before you condemn the compressor change the belt and while the belt is off as said above spin the tensioners and look for a bad one also check out the alternator they can be noisy when there on there way out

[ChiTahoe]

Yes that's the A/c compressor. I would install the A/c bypass kit till you save enough to get a new compressor and dryer.

Lmao you realize you just bumped a 2 year old thread right?

[SunlitComet]

you realize you just bumped the same thread 6 months after its last post.

Retorq, please do not use language like that here please. There are nicer and more appropriate ways of saying things.
