Having problems with your 2003 Oldsmobile Alero ?

Chirping sound 2003 Alero makes a very irritating chirping sound. I know it's coming from one of the belts. The dealership I bought it at replaced the belt and I've used conditioner. That helped but it's still there and very annoying. Could it be the pulley the belt is on? As far as I know and can tell, it does not affect the actual driving of the car - it runs great and I have had no problems with it!

Answers :

Start with the AC , when the sound starts, turn off the AC and see if it goes away. If that works, you have a problem with the AC compressor pulley. Check the other pulleys by taking the belt out and turning the pulleys one by one and seeing if it makes noise. Let me know how it goes.
