I have 2006 Santa fe .Its making a loud squeallike

Hi,

It sounds like the black serpentine belt. It's about $20-$40 and easy to replace. Or it could be the pulley. First check that belt.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/laura_08254539050d64db

The drive belts on the front on the engine. Replace all them.

Is it a "wine" noise that gets louder when you rev it up? Sounds like an idler pulley. Is it a 3.3L motor?

The pump runs off a belt as well, if there is a pump problem it might make the belt squeel

It's a loose belt for sure.

If you have a spring loaded tensioner, and the belt has stretched with time, the tensioner will reach the limits of its travel without tensioning the belt enough to prevent that squeal.

If it has an adjustable tensioner, tighten the belt up.

it sounds like the fan belt slipping try tightening it first

It could be a pulley. Best way to tell is to remove the belt and turn each pulley one at a time and see if you can either feel one not turning freely or try and duplicate the squeal. Keep in mind there is no load on the pulley without the belt on it so it might not be as pronouce as it would be with the belt on.

no its not a hard job at all www.alldatadiy.com and www.autozone.com also here is Drive belt diagram www.webcrawler.com wish you the best of luck Michigan Man.

It is either the tesnioner or the belt....easy way to find out is to spray the pulley that has no grooves....that's the tensioner. Spray it with WD-40 or equivalent, in the middle of the pulley. That is the bearing housing. Spray only that first. Start the motor...if it goes away, then you have found your problem. Try not to spray the belt.

If it still squeals, spray the belt with the engine running. If it squeals, replace the belt.

Has anything been done to the motor recenlty? If so, one of the pulleys may be a little off-centered.

Let me know what you find.

your senario revolves aroud the milage on your vehicle.should it be a high milage we can call it common.if you did replace the belts then the next step will be is to see hou deep the belt inbeds in to the pulleys.if to deep then it will slip and make a noise
