Question
I have a 2001 B4C Camaro. Shortly after buying the car I noticed a "chirping" or "squeaking" noise coming from the engine in the mornings before the car warmed up. As time passed it got worse so I took it to my mechanic and  had the serpentine belt and tensioner replaced. I had these parts replaced only a month ago and now that the weathers getting cooler im hearing the same sound coming from the engine again. I hear the sound coming from what seems to be the drivers side of the engine... and not necessarily from the belts. Any help would be greatly appreciated.

Answer
First thing...

Disconnect the serpentine belt and start your car. If you don't hear the sound anymore then its one of the accessories.

Reattach the belt and put a long metal extension or screwdriver on each accessory when the car is running. Put the other side to your ear and see if you can figure out which accessory is making the noise.
