Question about 2005 Kia Sorento

1 Answer

I believe it's my alternator belt that is squealing. It does this when cold and when I tax the alt. ie: turn everything on. like rear defrost,headlights,heater fan. after the squealing stops you can hear a humming sound which comes and goes. My question is. Is this a belt problem or the tensioner or the alternator itself? My kia does not have a volt meter guage but it runs good with everything on. I was thinking the belt tensioner as i have had this happen on other vehicles.

Check belt tensioner adjustment. Spray WD 40 on belts and pulleys and start. If no fix .it is most likely the rear bearings on the alt. before you buy a new one shoot some WD in the rear of the alt through the slits to the shaft. No fix take it to your local chain parts store and they will check it for free.

SOURCE: Battery volt meter is reading low, is it my alt,

HELLO THERE:
The most accurate way to find this out is to take the vehicle to auto zone and have them hook up the hand held diagnostic center to the vehicle and they can test both the alternator and the battery for you.
The best thing is that this is a free service that they provide ok ?
Hope this is very helpful for you
Best regards Micahel

SOURCE: how do i replace the serpentine belt that goes tothe alt. ?

You will need a breaker bar to release the tensioner. A breaker bar is a long ratchet that doesn't ratchet. The breaker bar size for your car is 1/2".

You will see a square hole on the tensioner and that is where the breaker bar goes. Put the breaker bar in there and pull on it until it gives you enough slack to pull the belt off. Make sure to pull the right way to release the tension. IF it wont release the tension don't yank on it try going the other way, It will help to have two people to do this job. You only need to pull it off one pully then slowly let the tensioner go back.

To put the new belt on make sure you run the new belt the exact same way as the old. Again you will need to release the tension from the tensioner and slip the belt over the last pulley.

Alternator squealing


Could be just the belt... if not the belt then most likely the alternator bearings are bad.. you can test this by removing the alternator and turning it by hand and listening to the rear for squeeks or a grinding sound.. good luck

How can I figure out what's squealing? Where can I find belt diagrams?


I had something similar with two seperate vehicles after replacing everything I could think of it turned out to be a bad bearing in my alternator on both vehicles.

95 jeep grand cherokee. Alternator charges intermittently only after engine squeals, belt NOT loose.


if the belt squeals why not fix that first? ?>?????
that is correct, if a shared belt resource, is seized it will cause any belt to slip and the alternator to stall , after all they are SHARED.
some alternators do have the regulator in the ECU. for sure.
why guess, tools are cheap. wana buy a tool.>
did you hand spin all shared pulleys to feel for seizer or use a $5
stethoscope on each for load bearing noise, so simple to do...
they sell this tool called a Laser RPM tool, point and shoot.
its cheap,
The correct RPM of the ALT is publised in the FSM and you can measure it.
i take my crank pulley diameter and divide it by the alt pulley diameter.
eg: one is 8" other is 3"
so the ratio is 2.66 :1
so at engine RPM of 800 x 2.66 you have 2128 rpm on the alt.
basic mech, 101.
so if the tool shows way less than that, then bingo, the pulley is slipping, BTW2 not all slips squeal. so.... the tools rule the world of mechanics.
here is the cheap tool i use to find things with wrong RPM.
i put a dab of liquid paper (walfart) on any pulley and this tool
picks it up and bam RPM exactly.
no hands getting caught in belts etc, no danger.

so recap
belt new.
all things on the belt, feel good spun
all things on that belt , sound good $5 stethoscope.
tension on belt , at spec.
if still bad out comes Mr
DT22334A
http://www.amazon.com/DT2234A-Tachometer-chemical-automobile-airplane/dp/B00BKUNOAW

in the real world , sometimes THINGs only SEIZE on the fly.
picture in mind a dry bearing that keeps dragging more as it spins faster. bingo. its bad. and gets worse at higher RPM and soon it
will seize 100% and throw that belt or shred it.

I cant pin down where it squeels
why not drop the belt (cold engine if shared with water pump)
and now it dont squeal.
easy huh, no belt , no squeal.
i truly hope this helps.
there is no reason to guess, besides a new unglazed belt.
ever.

2003 Kia Rio new fan belts squeal when lights,heat, or radio are turned on, especially when car is cold. caused a fuse to blow last winter


Hey Anon, Are you SURE you got the correct belt?? Something does not sound right about this...???... Double check all the pulleys when the belts are off...the alternator should spin freely, all the the idler pulleys should spin free..(ones that just spin and guide but are NOT connected to anything)!! This very thing happened to me...it was a $12 idler pulley that did nothing but spun and guided the belt..

Waterpump/alternator belt keeps breaking on 2000 mazda protege. belts squeal all the time then break


do you have a siezed tensioner pulley that could do it . remove the serpentine belt and check the idler puller, then the alt if it's siezed , the water pump pulley should turn freely also check what is siezed and making the belts squeel something's not turning.

When I turn on the rear defoster the engine squeals


This is your alternator belt squealing. The belt needs to be tightened or replaced. When the defroster comes on, it puts more load on the alternator causing the belt to slip.

Squealing losing power not chargeing batter changed alternator


If the belt is 3 yrs old or older, change it. If it has oil or anti-freeze or grease on it, change it. If new, add more tension to the belt.
