2000 chevy blazer 2dr 4x4
latly ive noticed a squeaking coming from my belt, a guy tells me to spray some silicone spray on it, or WD40, so i went got some WD40 and spray the belt and the squeaking stopped, but after running for about 15 minutes, it came back alot louder. Than i used some silicone spray, and pretty much the same thing, though it did work a little longer.
my question is, is there anything better i can use, or would buying a new belt fix the problem. i just got to about 90k miles. and when i accelrate, it gets louder. thanx in advance for your help.

Remove your belt, clean off your pulleys of the silicone spray and put on a new belt. I have found I don't get any more than 20,000k out of a GM belt before it starts to chirp/squeal. I have had better luck with the aftermarket belts (crosshatched design).

My guess would not be the belt but either the tensioner or idler pulley bearings are starting to go - common problem. Didn't say the mileage but alternator front bearings can also go but usually alittle grating or grinding with more of a chrip.

Re: 2000 chevy blazer 2dr 4x4
ok so i guess i should try first getting a new belt, seeing how that would probablly be the cheapest route. and swalt, u said the best ones are after market. im in chicago, il, we got autozones, would they have them, or where else might i find one.

Autozone, O'Reillys, Advanced - any of those places will have serpentine belts to replace yours. Figure on about $35-40 or so for the new belt. THey're easy to replace, doesn't take more than 10 minutes.

Re: 2000 chevy blazer 2dr 4x4
I'm using the Dayco PolyCog right now and I have no complaints with it. I found the GM belts seem to glaze up on the backside quite quick. I give my engine a good powerwash after each winter and detail it (not the belt), so that might be part of it, but I don't have the same problem with the Dayco.
