Can't find the source of the squeal


Year make and model ??
The belt could be glazed and slipping even if it is tight.
You could have a weak belt tensioner too.
The noise when the ac or heat is turned on can be the extra load from the ac compressor or the alternator. The compressor cycles on and off especially in defrost mode.
The load from the alternator is the first noise of the day. As the belt warms up it becomes better at handling the load of the accessories.
Even tho the belt looks fine, you may have to replace it to get rid of the noise.

What would cause whistling noise near pully and belt area noise gets louder with acceleration


The engine serpentine belt may be worn or wet. The belt slips, causing a high pitched squealing or whistle noise. The other possiblility is a bearing beginning to go out on one of your belt driven components

My engine upon starting squeals and gets louder when i accelerate, every once in s blue moon it will stop for a few mins or quiet down????? help


There are only 4 things that will cause a belt to squeal.
1. A bad/worn-out belt
2. A bad or misaligned pully or pulley bearing
3. A bad belt tensioner. (pulley, arm, pivot, or spring)
4. Malfunctioning or bad component (alternator, power steering pump, A/C compressor, etc.)

Remove the belt and check ALL pullies to make sure that they rotate smoothly and do not have any horizontal play in them (indicating worn-out bearings). Make sure that the tensioner pully swings freely and does not bind in its travel at any point and that it is properly aligned with the other pullies. A good way to check for proper alignment is to look at the belt position on the pullies with the engine running. If the belt is running on the edge of the pullies instead of in the center, it is usually caused by a bad belt tensioner or a bad bearing on one of the other pullies.

Check the belt for chunks missing, torn or cracked ribs or shiny "glazed" edges, ribs, or back.

You state you changed plugs and wires - Do distributor cap & rotor? If not you should then set timing. That should cure hesitation (might change fuel filter also and run good fuel system cleaner through it)
Prob 2 - sounds like a u-joint or possible brake pad/rotor issue. Does the squeal only happen in mornings when cold? Sometimes after sitting overnight, rotors get condensation and when backing out they'll squeal/grind. Somethings to look at...

At startup, amp gage low, lights flicker. belt squealing. then after warm up, gage normal no squeal. alternator bad? Use to do when blower motor on now all start ups.


Thats what it sounds like. That would cause all your problems. You could start the jeep and then take your hot side battery terminal off. If it dies asap, your alternator is bad. Hope this helps. Best of luck.

I get a loud squeal from the fan area only when


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.

Serpentine belt replacement how to loosen belt


To loosen and remove the drive belt on a 2004 Toyota 1.4L engine you simply use a wrench and pull up on the spring-loaded tensioner.1d45837.gif
You should be aware, however, that if you are experiencing problems with belt squeal or rattling noise, there is a Technical Service Bulletin (TSB) for your vehicle that provides information for an updated tensioner assembly.
