If there is a slotted bracket under the alternator then loosen it and push the alternator down ( if it is difficult you may have to loose the mount bolts as well) If there is no slotted bracket the adjustment will be on a idler pulley. Loosen the pulley shaft nut and behind the pulley there will be a long adjusting bolt. You may have to remove other belts to get the belt you want off. It will not be necessary to remove any fans as the belt will come off by placing a section of the belt between the blade and revolving the fan until the belt is on or off

Unless something has bent this should not be an issue. The only other time I have run into something like this is when the tension is not correct on the belt. If that doesn't have the spring loaded tension pulley you will find an adjustment on the alternator bracket. If it does have a spring loaded system then you need to replace that spring in the tension arm.

If the pulley wheel doesn't seem to connect to anything else it is probably just your tension pulley.
These are only to keep the serpentine belt tight while allowing it to adjust to some limited extent.

You can replace the pulley itself. These commonly grind when they go bad, or in your case it sounds like yours just broke off..

What makes a belt squeak?


Belts squeak for the same reason tires do when they spin. They are slipping. Something isn't turning as fast as the belt wants it to. On ford it's usually ether the idler sprocket or the tensioner. If you remove the belt and try spinning all of the pulleys by hand.( note the crank wont spin freely) you will usually be able to tell witch ones slipping.

On a 2005 Hyundia Sonata, should the crank shaft pulley feel loose? I recently have gone through 3 steering wheel belts. I assumed the first belt frayed because it was old and brittle. The new belt...


No, there are no bearings in the crankshaft pulley. No, it's not a common problem. The pulley is simply loose!

First determine if the pulley bolts to the harmonic dampener or if it's all one piece.

If one piece, then there is probably 1 bolt in the center of the dished portion that has loosened. If not repaired, the harmonic dampener can fall off, possibly damaging the end of the crankshaft.

If it's not 1 piece, then there will probably 3 or maybe 4 bolts in a circular pattern around the edge of the pulley bolting it to the harmonic dampener. Check to make sure all bolts are there and tighten down. A flexible mechanics mirror comes in handy for seeing exactly whats in the dish of the pulley.

If I were you, I wouldn't start the engine until this is properly resolved.

Good luck!

The crank shaft is not froze up if the engine is running. Without knowing how severe the situation is, it is probably best to remove the belt and feel each pulley or drive wheel to detect the condition of the bearings. It should be very clear which pulley bearing is loose by "wiggling" the pulleys. One of the pulleys will have a lot of play in the bearing. Also the pulley with the bad bearing will be hard to turn by hand with the belt off. Be sure to check every pulley on that belt circuit, except the crank shaft, you can't turn it by hand.

I have a 2001 Sonata. I have a squeeling pulley.


It sounds like you have a worn or streched belt making the sqeeling noise. Whenever you turn on a
device in the car that draws a fair amount of voltage
ie. a/c or headlights it will cause increased drag on
the alternator and if you have a loose/worn or glazed
belt, it can slip around the pully making the squeel.
To adjust the alt-a/c belt loosen the mounting bolts
on the tensioner, then use the adjuster bolt behind
the tensioner pully to loosen and tighten the belt.
Be sure to check the belt for cracks bald spots etc.
While the belt is loose spin the pullys to make sure
they all spin freely. Also I would replace the belt just
to be sure. Hope this helps
