I have a 2004 Chrysler Pacifica and the belt is squealing away, they car has 50k on it and I purchased it used, I tried belt dressing and still is squealing, I am unaware of how old the belt is but on visual inspection there are no cracks within the belt itself along the groves, I did read somewhere the 2004's had problems with squealing belts if thats the case does anyone know the fix? As well should I just try replacing the belt first as I am unaware of how old the belt itself is and then go from there... it it isn't a new belt is what it needs to fix the problem could it possibly be a bad tensioner pully??? Thanks to all who answer

Re: Belt Squealing on 2004 Chrysler Pacifica
I would try replacing the belt first because it is a cheaper fix. Are you certain it is the belt? Have a mechanic check your alternator. It could be that actually making the noise. I had a vehicle that made noises and it turned out to be a water pump going bad. I hate car problems!

with car off and keys in pocket open hood and check all pulleys and components something not turning possible seized such as idler pulley alternator noise is belt being dragged over something not turning
50k isn't new but also isn't that high a milage , how old is the belt ,as age as well as mileage are the factors when replacing belts , chalk dust or french chalk , which are the same thing , thrown onto the belt just as starting should stop the squeal , the squeal is caused by the inner side of belt that runs around the pulleys becomes shiney and cant grip as well as it used to
when changing a serp belt i recommend changing tensioner and idler pulley's also that could be causing the squealing you mention were all pulley's checked for free spin when belt was off ? Not really sure what would cause hesitation unless you have a serious drag on serpentine belt
No! It appears that your Serpentine Belt needs replacing. The squeal is due to the belt slipping because of it's age. The serpentine belt on a Chrysler is self adjusting so "high speed glaze" or "cracks" in the wide belt will tell you it needs replacement. The only other belt you have separate from the Serpentine Belt is the one for the Air Conditioner. Another word to the wise, never use "Belt Dressing" on these belts. It only makes them deteriorate faster. If you have an old table candle, while the engine's running, place the wax on the underside of the belt and the squeaking should go away. (I feel like, 'what to do with those darn Holiday leftovers'). To see the belt jumping or squealing, have someone start the van and look under the hood while they turn the steering wheel back and forth and you will see the belt "shudder" or "jump" while squealing. A timing light being pointed at the belt will also give you a "stop-action" view of the belt.
Click on the following: free, direct Link. It has several Diagrams including the Serpentine Belt Diagram for your 2004 Chysler Pacifica 3.5L DOHC V6. It has the Instructional and Directional Diagrams that will help you.
Standard Rules for Installing the Serpentine Belt with an Automatic Tensioner: a. Pick a Pulley that is most easily accessed. This will be the last Pulley that the belt will go on. b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right. c. Using a Serpentine Belt Tensioner Tool or Wrench (See Diagram in Link: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley. d. Using your other hand - Pull the Belt up and over the Last remaining Pulley. e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them. Let me know if this helped, or if you have additional information questions.

get away from the shade tree. have your a/c pressures checked. the compressor may be on its way out. make sure the cooling fan or fans are working. did you use a quality belt, or some cheap brand from otto zown? if the rear a/c is running but not the front, the a/c compressor is not engaged, thats why is doesnt squeal.
You have a loose belt on the A/C. On most new cars that is one big belt that drives everything on the car. If when you look at the belt on the grooved side, do you see cracks on the grooved part running across (from side to side) on the belt? if so, it is in bad need of a new belt. A new belt should stop the squealing noise. While you are replacing the belt also check the belt tensioner to ensure it is in good working order.
