Belt wont stop squealing - 2001 Mitsubishi Galant

Sounds like the compressor is seizing up or a idler pulley bearing has failed.

hi

the squeal on a belt when the engine is started is a indication that it is loose and slipping

it needs to be tighten or at least changed, sometimes people squirt a little oil on it to lubricate it so it stops making that noise but it wont stop until tightened or changed

Belt tensioner seized or bearing on pulley going

Looks like you need a new belt. Inspect the belt for any sign of damage like cracks etc. If belt appears fine then just tighten it. Add few drops of brake oil on pulley (surface which comes in contact with belt) to stop minor squeals if left after tightening the belt.

it may not be the belt that is the problem it could be the A/C clutch that is squealing or the A/C compressor unit cheers.

I would guess belt, bearings typically wont stop unless they are lubed.

what brand belts are they? try gates where other belts stretch these will not,make sure ac not gat ot much freon in it or fans not cooling condenser down.this will make ac compressor try to lock up,,,,,i would try an old mans remedey ,axle grease on grip side of belt,not any thing else ,every thing else will come off,belt dressing will make things nasty and wont stop squeal

sound like alternater belts you changed one may not have been as good as it should try again

You have a loose belt on the A/C. On most new cars that is one big belt that drives everything on the car. If when you look at the belt on the grooved side, do you see cracks on the grooved part running across (from side to side) on the belt? if so, it is in bad need of a new belt. A new belt should stop the squealing noise. While you are replacing the belt also check the belt tensioner to ensure it is in good working order.
