Your serpentine belt tensioner may be bad,not holding enough tensioner and not letting your alternator keep a charge on your battery,get some one to sit in your vehicle,open hood,have them start it while you watch the belts turn and have them rev the engine up to see if the belt turns loosely.another thing to look at is the A.C.compressor locking up .Power steering pump could be locking up,just check it out while it's running and see.

SOURCE: squeaking noise in engine. not serpentine belt.

You might have a dry bearing in the alternator. I've had a squeaking noise from them.

Testimonial: "thanks! the noise is not constant. it cycles with the rpm's. it like squeak-squeak- squeak and progresses as the rpm's increase."

SOURCE: 1999 suburban squeaks at startup then fades away

Check the belt alignment and also check for other worn bearings. Crankshaft damper may be coming apart.

There is a small metal tab on the brake pad made to make noise
when the brakes are close to worn out,the noise goes away under
braking,I suspect the pads are in need of replacement.Make sure
the rear brakes get checked for proper adjustment at the same time.

I drove my 97 blazer yesterday and ran the a/c. It did not run cold but was cool. After getting back from my 4 hour drive, I went home and let it sit for a couple hours. When I went back out to start...

Probably the compressor causing the belt to squeak. Try spraying just a squirt of wd40 on the drive side of the belt. It the noise goes away, its the belt. If not, its the compressor drive.

I have a 95 nissan 300zx twin turbo and theres a belt squeaking whenever i turn the car on. it squeaks louder as the rpms go up. after a while it goes away but sometimes if i rev high it starts up again....

almost certainly the fanbelt is in need of replacement/tightening,on this car the alternator is the adjuster,loosen the bolts,lever the alternator away from the engine and then tighten the bolts.DO NOT OVERTIGHTEN THE BELT.1/2" play in the longest run is fine.
