99 squealing noise

my 99 grand am gt makes a squealing noise when accelerating anyone know what might be causing it

where does the noise sound like its coming from? Under the hood, from the wheels?

check your serpinetine belt , if its worn or cheap it will squeek or if theres some power steering fluid leakin on it it will squeek too

if the belt is squeaking, for a cheap fix for a little bit, take a peice of lumber crayon (3 bucks at home depot) and run the car and rub it on the ribbed part of the belt, it will stop the noise for a little while. BUt watch your hands!!!!

It is the serpentine belt. I had the same problem just two days ago. I had a leak in intake manifold (or gasket...whatever) and I guess it leaked onto the belt and when they cleaned it, it started to squeak when accelerating. They replaced it and now the squeak is gone. The belt cost $77 CDN for just the belt. They covered the labour under the warranty work for the intake.

If the belt doesn't do it, it could also be the belt tensioner is no longer applying the right amount of resistance. I had to replace that after replacing the belt itself failed to solve the problem, although I had more of a chirp than a squeak.
