loud screech from engine

hey guys i have a 1998 GSX (64k miles) some times when i start the car up there's a loud screech comming from the engine area. It does that for a few secound (1-5 seconds) and stops what could be the problem? HELP!!

mine did the same thing (possibly). it started after i replaced the alternator belt u might have it to loose. i tightened it up and it stopped makin the screechin noise.

belts for sure. Unfortunately, I am extremely experienced in this area. It is a DSM thing, these damn belts screeching...


1) pulleys could be put in BACKWARDS (as was mine, though the difference was only 0.05mm, no more noise after dealership put it in correctly).

2) bad quality belts. Recently replaced belts, guy put in some new brand with cross-thacthed belt tread pattern unlike the regular OEM stright-lane grooved belt. Screeched like a MOTHERF(ER no matter what adjustment was made. Most likely the AC belt and the power steering one. Put stock belts on, problem solved, no problemo, hasta la vista, BAYBEH! :bananadie

3) belt tensioned incorrectly. Usually solved the easiert, tighten or untighten accordingly

4) buy a Honda. Pick this one if you wanna get shot. :nono: hehe (for legal reasons, I must put here that I was just kidding about getting shot.

Right; unless the car has been in for service recently where they would have taken pulleys off (i.e. timing belt job), I would guess it was probably an old belt that has stretched or the mounting brackets of your alternator, ac compressor, or power steering pump not being adjusted properly.

Did you just get the 60k mile service done? If so, chances are the mechanics didn't tighten the mounting brackets enough to set belt tension to spec. Take it back, show them the belts squealing, and they should fix it if you have receipts.

my car also has this problem with noises, im quite sure its the belts or 1 of of them i should say, i would have some one start your car for you while the hood is open and stand there in front of the engine to try and see where the sound comes from im sure you could at least find the general area and narrow it down a bit..
