2000 jgc making squeaking nosies from belt

Belts? Mice? Hallucination? ALL DEPENDS ON WHERE THE "SQUEAKING" IS COMING FROM.

Open the hood. If the squeaking is coming from the area of the serpentine belt, it is probably time to replace your belt. Also, check all fluid levels.
If the squeaking is coming from a particular pulley (such as the air conditioning compressor or the power steering hydraulic pump), there may be a problem with whatever the pulley is attached to.
If the squeaking appears to be coming from outside of the car, you are scaring the mice or hallucinating.

Alternator belt is loose or there is oil on the pulleys or belt making it slip instead of charge the battery. Check belt tension on your belts

Squeaking? Maybe a mouse? lol.
This could be many things, from a fan belt squeak to a suspension bushing squeak to a loose bolt squeak. You need to try and pin point it a little better. Have a passenger put his ear to work by trying to locate it if it is coming from inside the drivers compartment.

power steering fluid full might just need to top it off

Replace the belt and take a look at the pulley while belt is off, 90% of the time the squeak is caused by the belt.

Change the belt

Could be a belt that is too loose.

Is the smell like burning rubber?

Is the squeak coming from the engine compartment?

Does the squeak go away when you rev the engine?

If yes to these questions it sounds like a loose belt. You would need to replace it.

well the belt could be loose or the compressor may be seized.....or the belt may be old and squealing.

have you tryed replacing the belt when and if you replace the belt check the pulleys that are driven by that belt for nosie do not try spraying any thing on the belt just make things worse kdc744
