What is this darn squeaking / chirping noise I hear ?!!
this is driving me nucking futs ! I get this chirping noise coming from something up front of the engine at idle, which is worse when the engine is cold. It turns into a squeal as the engine is rev'd. I can put a 15mm wrench on the tensioner for the main serpentine belt, and if I pull it to where the belt is tighter, the chirping gets worse. From the speed of the chirping, I figure either the water pump or the P/S pump, it's too slow to be the alternator. Is the ANY way I can narrow this down ?? Please any help would be greatly appreciated, I am tired of playing the "replace something and see if that fixes it" game....I have already replaced the tensioner pulley and the other, stationary pulley , and the belt - it is NOT the belt squeaking !
Also, if I take the belt off and turn the power steering pump, the water pump, or the alt. by hand, each seems to turn smoothly. i'm out of ideas.
Sorry for the long post !

It's one of the idler pulleys. You'll have to listen up front and try to pinpoint which one. Very common problem. I had to replace one of mine when the car was only a year or two old.

Anyways, back to the present: I also took the smaller belt for the A/C completely off to eliminate that. Noise is still there. Check P/S fliud, it is full. The sound seems to be coming from either the power steering pump or the water pump, I can't tell which. But if it were the water pump, don't they usually start leaking when they go out?

i had this problem, took it to the dealer and they replaced the belt and a leaky waterpump and problem is solved, although it still squeaks every now and then on startup after a rainstorm it goes away.

also check your header gaskets, I too have the FLP's and I tagged a speed bump on a lowered car and the chirps started 2-3 days later It sounded like I had a bird under the valve cover and was the worst at start up and wheny you hit the arc of the rpm range. good luck

Water pump could definitely make that noise. It could leak a little steam and never show. It might not leak at all either. Start the car for a second with no belt at all and see if it goes away. If the noise does go away, it most likely is the water pump.

UPDATE: well I should have quessed the water pump. I quessed the P/S pump, and replaced it. Wrong. Squeak is still there. It is worse when the engine is cold, almost goes away when engine is hot. No leaking at all. Only two things left it could be: water pump or alternator. I doubt the alternator, I just replaced it with a 160-amp one not a year ago. DAMN, I HATE THIS QUESSING GAME!!
Thanks for the replies. I know it's hard to guess what a noise might be from a description on a message board. Especially when I can't tell what it is with the car right in front of me!!

UPDATE:
problem finally resolved. 'Twas the WATER PUMP !!
Installation was relatively painless. But I was doing some cussing at GM for using those stupid paper gaskets. Which of course, you have to scape off. The new pump came with metal gaskets with rubber o-ring type seals...why didn't GM do that? I could have done the whole swap in less than 15 minutes, if it weren't for that gasket-scrapage.
Thanks again for all the replies !
