Squeking in front of the motor on the car

It could be your serpentine belt. Road tar can get into the groves of the belt and cause sticking to the pulleys which will translate into a squeaking or chirp sound. To check, with the engine running use a spray lubricant (not water and above all not belt dressing. The dressing will only make matters worse) If the sound go'es away that is your problem.

The belt keeps making a squeeking noise it sounds like the belt drive.. what can i do to stop that noise??

Check to make sure the belt is not loose. While you're checking the belt make sure that the belt is in good shape. Replace the belt if it has nicks or cracks.
The belt may be glazed (belt develops a hard glaze from age, dirt/oil hardening) and slipping. Try spraying 'belt dressing' on the belt. 'Belt Dressing' can be found at your local auto parts store. Ask the counterperson for it.
There could be another reason for the squeeking. One of the pulleys may have bearings going out and the unit may have to be replaced.
Let me know if you have any more questions or problems. Thanks.

I replaced the altenator and the serpentine belt two weeks ago. Now i hear a squeaking noise. I tried a spray for the belt but the noise is still there.

Check your tensioner pulley -- if you do not have enough tension on the serpentine belt, it will slip on the pulleys and cause a squeaking noise (very loud and high pitched). if you push on the serpentine belt with your hand, it should not more more than about an inch -- if it does, you are low on tension. If it does not have any give at all, then you have too much tension, and one of your pulleys might not be turning properly, causing that same noise. If your tension is right, and your car is still making that noise ... and belt dressings (the spray you probably used) are not working to stop it, then it might be a piece of rubber stuck on one of the pulleys, but this usually will not make that sound ... just smoke and a burned rubber smell.

My engine squeaks when ever gas is applied or when gears shift, what might be wrong?

The only thing that I know of that will make that noise is the belts . get a can of belt dressing and spray the belt(with engine off) and the noise will go away. check the belt to see if it is tight and is in good condition.If your engine has just one belt the belt dressing should stop that noise but make sure the belt is in good condition .

Squeaky noise from my belt area. I sprayed dressing on it and I believe its worse. I understand that you can't tighten belt?

It may not be the belt, but it could be a bad bearing on the Alternator. If the belt is loose, it could be a bad Belt Tensioner. The Tensioner is what keeps the belt tight.

Any time I accelerate, something under the hood makes a screeching noise...sometimes louder than others. It sounds like a belt wearing

You are probably right ... probably worn ... probably loose ... probably has a little anti-freeze spilled on it. If it is troublesome ... you can treat it with belt dressing ... which MAY make it worse ... or you can replace the belts. You are probably doomed to some squeeking on your 12+ year old car ... sorry ... If you replace the belts, make sure you clean all the pulleys ... Spray Brake Cleaner is good for this.

In my experience ... just like spilled milk ... one drop of spilled anti freeze suddenly looks like 10 gallons as far as squeekability is concerned.

Another option ... turn up the radio ...

How can i stop my AC belt from making noises when my AC is on

The reason your belt is making a noise is either your belt is worn and needs replacing or the belt tension is out of adjustment and needs checking and adjusting.
It is a good idea to replace it anyway specially if the belt has small cracks on the inside.
