Belt squel from hell

[johnathanf1lm]

Hello i have a 2005 kia rio which pretty much for the last 2 years has a squel when you start up churps until warmed up. Squels at idle (til warmed up) when the ac is on, headlights are on or steering wheel is all the way turned. Now be for giving me the obvious its the belt, it isnt. 2 years ago had dealer replacef belt (bad mistake) and put the wrong belts on. After a year squel got bad so replaced and noticed they werent the right ones (smaller groves) replaced with auto zone brand. Went away for a bit, came back and used belt spray to get rid of it for half a year then it started doing what it does now. Replaced belts with gates ones, went away for a week slowy started coming back. Notice power steering pump locks when fully turned, replaced power steering pump. Went away for a week now its back along with the noise when fully turned. Alternator was tested and passed (when the belt doesnt sqeal. On my car there are 2 belts one for ac and power steering, one for.water pump and alternator. When.it squeals dash dims sometimes. Im all out of ideas pretty much. Im sure im losing even.more gas then idle does at idle.

First one I read someone had water pump bearings making noise

Pull the belt, turn and spin all pulleys to see if you can hear and or feel something.
Another thing, could be a misalignment of a pulley.

Removing one belt at a time will isolate the noise.

Yes, misalignment, including run out and worn bearings.

Don't use belt spray as that is only temporary fix. After that it makes things worse.

If the belts (and pulleys) are run too long while slipping (more than designed) they will polish up and increase the likelihood of slipping, even if the initial cause is corrected. A light scuff up, of both belt and pulley grooves, with some fine - like 800 - wet and dry emery paper sometimes helps.

Ill have to try the sand paper. Pullys arent missalined and belt stray hasnt been used in over a year

[johnathanf1lm]

And pullys spin like they should. Major thing ive been noticing is when it goes into a full on squeal the squeal doesnt get louder with the revs but instead stays the same pretty much. Before i changed the belt it did

I'm going to ask the obvious, did you tighten the belt? Does it have an automatic tensioner?

[johnathanf1lm]

Hey its okay to ask but yes i have tried that too didnt make a difference really.

Take a short piece of hose (2-4 ft) or tubing, put one end in your ear and move the other end around the belt until you find the spot where the noise is loudest. Cheap and effective mechanics stethoscope. Chumly
