Startup Noises

[sniver]

When I start my car up ,for about 30 seconds, one of the belts will squeal ,and then go away until the next time i restart the car. All my belts are tight, though i think that the noise is coming from the belt with the a/c compressor. Im am rather frustrated by this belt, does anyone have a cuase, and better yet a solution for me? Any help is appreicaiated.

Check the harmonic balancer (crank pulley) for separation. If ok, remove all belts and put them on one at a time until the source is found.

make sure the belts are not too tight, try spraying some silicone on the belts.

Does it continue to make noises after you drive for a while? If so, your bearings in your water pump or alternator may be bad.

Yes I have had it on 2 differnet DSM's when it was the alternator bearing(s). If it gets progressivley worse, and is more noisey when you run electrical components, that points towards the alternator bearing IMHO and in my experience.

i have the same problem too ( current ) and i have no clue whats wrong with it. it sounded like it was coming from one of the belt but ### makes it worst is when i turn on my A/c it makes the sounds even louder and longer but once i leave the car idle for 2-3 minutes its gone till i start my engine again.
But when i turn off engine n restart it sounds is gone i have to leave engine off for at least 3-4 hours for the sounds to come back. If any of you guys know whats wrong please PM me tnks
