check to see if the belt is cracked or hard. hard or cracked belts are prone to sqealing. also you can use a stethescope or screwdriver(the cheap way) to listen to the pulley itself. carefull not to get caught in the belt while doing this.

This is most likely your belt squealing and not the clutch itself. Try some belt dressing available as a spray on from all parts store. If this stops the squealing you have a varnished belt and probably should replace it soon.

How do you get rid belt squeal on a 1999 olds intrigue?

You should not be getting belt squeal because it is a serpentine belt, and not a v-belt. The squealing is most likely a bad bearing in one of the pulleys. Whatever you do, do NOT use belt dressing on a serpentine belt, as this can cause more problems. I suggest you remove the belt, and turn each pulley by hand and listen for the squealing. Some, you may not be able to turn though, such as the crank pulley. They should turn smoothly, with no noise, or intermittent resistance.

How do you replace the idler pulley on a 1993 Geo Prism?

I assume you mean the idler pulley on the A/C belt. I have not replaced this particular item but it should be simple. Looking from the top of the engine compartment on the passenger side you will see the idler pulley with a mounting/locking bolt which attaches the pulley and the tension adjusting point immediately above it. Loosen the pulley locking bolt by turning counter clockwise. Relieve belt tension by turning the adjuster bolt counter clockwise. Remove the belt and pulley. Replace in the reverse order.

When my brake life is at 10 should they be replaced?

I have no idea what you mean by "brake life is at 10," but there is a way that I always know when to replace my brake pads. When brake pads wear down quite a ways, a metal clip will start to touch the rotor when you apply the brakes. It will cause a very loud squealing noise (metal clip on metal rotor), and it means that it is time to replace your brakes. It was designed that way. Once you hear the squealing, you can drive like that safely for weeks or months, but the squealing noise will be very irritating. If "brake life is at 10" means that you only have 10% of your pads left, then you should change them.

On Lexus ES 300 Pulley that is located beside the engine and is on the serpentine belt with the alternator is sqealing what is the problem?

If you're describing the idler pulley or the tensioner pulley, it's probably a bad bearing. Pulley bearing failure is common and relatively easy to repair. Remove tension from the serpentine belt then turn the pulley back and forth with your fingers. It should make no noticable noise and should turn smoothly. If you can hear any grinding noise or if the pulley feels like the bearing is grinding, replace it.
