Im at a loss here after about 600 miles into my break in and all the sudden I sarted to get a chirping noise under the hood that turned into a constant annoying squeel. I replaced all my bearings, tensioner and belt when i reinstalled my motor a few weeks ago so i wouldnt have this issue, but here we are once again. pur a little water on the belt an the noise temporarily goes away. the tensioner seems to be bouncing a little bit now so Im not sure what to do. As you know its not a 10 minute job to change a belt on a vortech car its time consuming. Any thought or rememdies you all have ran into. The belt i used was a NAPA gates 081079 belt and it is on the tight end so its not loose. Ive tried cleaning the belt and nothing seems to help.

What about your alignment? That's usually where a chirp noise comes from.

What position does the tebsioner sit at when the car is off? Like 11 o clock or?

If I had to guess, I'd say the tensioner itself, not the pulley, is worn.

My alignment is good belt rides on all the pullies, and the tensioner is nice and tight. being a do it youselfer i got this ideal to rub gold bond foot powder on the belt and see if it would dry up anything that came into contact with it after all its designed to remove moisture right? So hmm sounds ****ing retarded but I did it and 100 percent of the squeezing is gone lol so now what? Lol that was the dumbest thing I ever came up with but it worked. So it must be in the belt, Hell even with the ac on it's quiet as a mouse.

Seeing as how you probably dont wanna keep.around a stock of foot powder for your car, i would look for a small leak dripping on the belt, or possibly wetting a pulley. The foot powder might only work for so long. Use a bright white flashlight to help see moisture, it shpuld reflect nicely off of those black pullies and matte grey timing cover. One item i actuallt found works is a belt conditioner, use VERY little or it wont help. CRC Belt Conditioner fixed my squeak, applied it once every oil change, regardless of noise.

Im not able to duplicate the problem again after claening the belt with the powder, it must have acted like a degreaser and cleaned off whatever was making the belt squeel. Ill look into CRC belt conditioner if I have any more issues. Thanks

Reviving tis for a bit to get some more input, the powder obviously was a bandaid. Could the belt be bad? its a NAPA gates belt, and im really starting to not like this brand at this point. Should i order an original Gates belt?

Is it squealing at WOT or quick blips of the throttle? Does it squeal on startup? If so that means the belt is slipping. I had that issue when my belt was alittle to big.

I am not sure why you put powder on your belt. Powder acts as a lubricant. If you want to hear that puppy scream put some belt dressing on it. Belt dressing tries to make is sticker.

If the belt is squealing then it is too loose for the application. You said your tensioner was moving. With your pulleys you are runining a lot of pressure. Perhaps, the stock tensioner just can't keep up. It is not suppose to move when you work the throttle. Yes, I know some say it will, but if it does it is putting slack in the belt... thus belt squeal.

I had sort of similiar issue and i keps replacing the idler pulley and it would eventually come back finally i just spent $30 and replaced the tensioner pulley arm and all and it went away. But im not sure if that is your problem but if it goes away don't be surprised if it comes back. and even though you replaced everything doesn't mean something wasn't a great quality part to begin with. just my $.02

It's not really squealing it is chirping, my belt is so tight I almost can't get it on. I did the test you suggested and when I apply throttle the tensioner is as stiff as a board. This started after 500 miles or so I've tried water on the belt too just a few drops and it stops chirping.i vent hear it chirp once I take off cause my car is so loud. But it chirps at idle.

UPDATE, chirp is gone, my brackets was out of alignment causing my belt to chirp. I put in additional spacersto fix the alignment and Chirping immediately went away. Thanks to everyone Reps going out.

Excellent. My first belt lasted nearly 30,000 miles. My second one around 20,000. Then I lost a spacer changing the belt. Mine didn't chirp, it just started shredding belts.

Since i did the 8 rib upgrade I had to add spacers to compensate for the wider pullies, but they were not enough. After adding a specific size washer problem went away. Thanks
