Loud squealing sound in my engine

I have a 05 Jeep Wrangler Unlimited: every time I accelerate there is a loud squealing sound in my engine; I changed the tensioner pulley, idler pulley & Serpentine Belt. The sound is still there. What else could it be??

    I changed the belt, I also used a belt dressing, & the consistency of the noise is exactly the same, which makes me think its got to be somthing else. any ideas?

    I have the same issue with my 2004 4.cyc. wrangler. Ive tried belt dressing as well. Any solutions?

    I started with this problem 2 days ago...sounds kinda like a flock of turkeys in my engine compartment when at idle and increases in speed as I accelerate.

    I changed my serpentine belt last night with no improvement and was going to go the same route of checking the pulleys to see if it's a dry bearing. I'm also going to keep an eye on the water pump and see if it's leaking over the next few days.

    I will let you know if I find anything out!

Very loud squeal when accelerating and loss of power

How many miles? V6? Have you had a tune up(spark plugs changed..AT LEAST)? Should be changed about every 60,000 miles, according to the manual. Does your engine burn oil? Check your intake rubber tube, vac lines, pcv tube for crack. Hopefully your catalytic converter isn't the problem due to above...

Cold weather squeal

Check your belts and pulleys. Belts should not be cracked and pulleys should turn freely with no noise.

06 Jeep Wrangler making a loud clincking or grinding when turning

Hi there,

By any chance is the transfer case engaged?

A locked drive train could account for the noise being made only on turns.

Bring the transfer case to neutral then back to 2-high.

Or try to duplicate the problem by putting it into 4-high. THAT way the dealership would know exactly what to look at.

I have a 1990 jeep YJ replaced the alternator and now there is a loud screeching noise replaced the belt,replaced new bearing in idler pulley still makes a loud screeching noise?

If the belt is not tense enough it will squeal, so make sure it's tight enough. Otherwise you can use a stethoscope or long screwdriver up to your ear to isolate the source of the noise.

I have a 2008 Jeep Wrangler Unlimited, and bought it new. I perform regular oil changes, and drive very little. A few months after the last oil change I noticed the oil light come on very briefly, then...

You probably spun a bearing. My wifes 2000 ford mustang did the same thing she never checked the oil and she said the oil light would come on briefly and oil empty filled back and knocking during acceleration and idle tore apart motor and there were three spun bearings.

Loud squealing sound in my engine

Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.
