How To change idler Pully on 2000 Kia sadona Van

COULD BE A BAD BEARING IN THE IDLER PULLY OR THE TENSIONER ON THE TIMING BELT OR THE SERPENTINE BELT. IF ITS A SQUEEL IT MAY BE SOME COOLANT GOT ON THE SERPENTINE BELT. TRY TO WASH THE BELT WITH WATER AND LET DRY COMPLETELY. IF NOISE REMAINS RETURN TO THE SHOP THAT DID THE WORK.

The idler pulley has a bearing in it. When the belt is off try to spin the pulleys and see which one is bad. The big box stores carry these, there cheap and easy to replace.

start the car but do not drive it. look at the belt when it is running. if belt hops around then the tensioner is bad and not holding belt tight enough. or the belt itself may be bad. alo check for a bad idler pully for the belt.

your belt pully prob needs gresing up or bearings on way in wheel wer belt goes over

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

Although a KIA manual will state that this is an interference engine, it is not. I know because I have replaced a shredded timing belt on my used 2000 Sportage to take it home and it ran great. Just recently, the timing idler pulley bolt broke while I was driving causing the belt to come off. I replaced the tensioner pulley and drilled out and re-tapped the idler bolt hole and installed the new idler and the belt (it was only 2 months old at the time) and it runs great again. THESE ARE NOT INTERFERENCE ENGINES!!!! you don't have to tear down the top end of the engine to inspect for any damage and it is very simple to install a timing belt on this motor as long as it is done properly.

the belt is probably burnt replace and check the tentioner and idler pully for play and replace if loose

if you have climate control the a/c comp. comes on
intermitently if the clutch is going bad thats a suspect also the idler pully bearing could be tired
or the ps pump could be binding.
one way to narrow the field is the next you shut it off
after driving a short time see if any of the is noticably
hotter than the others thats a place to start.
hope this helps good luck

A slight squeel when starting is most likely a loose belt which just needs tightening up. If it was the pulley the sound would not stop.

depends on which v8 you have....the 4.7 the routing is as follows it goes under the waterpump pully over the alternator down and around the power steering pumpto the crank...it goes under the bottom of the crank to the idler pully.the flat side of the belt goes ver the idler then around the automatic tensioner to the ac compressor.
on the 5.2 and 5.9 it routes starting at the idler pully the flat side goes undr the idler the up to the ac compressor around the compressor and down to the power steering pump ... around power stering pump to waterpump where the flat side is against waterpump pully around water pump down and around crank up it automatic tensioner....around tensioner and up and over alternator
