Serpentine Belts
A serpentine belt is a single, continuous belt utilized in driving devices – such as power steering pump, alternator and others – in an automotive engine. First used by Mercedes-Benz, the belt is more efficient than the older multiple belt system.

How can you unfreeze the serpentine belt adjuster on a 1992 Dodge Grand Caravan AWD?
Sorry to say you will have to replace it. You can not free it up, and if you get it freed up it won't be free for long. The bearings are worn out and this can be cause by two things normal wear and tighten it to tight>
Why does a new serpentine belt squeak?
You have a bad bearing in one of the pulleys. Remove belt and spend all the pulleys by hand, they should be smooth and quiet.

2 people would be better to do the job.
Ask someone to turn the tensioner bolt (see diagrams from web pages above), clockwise direction (about 45 degree) by using 19mm socket and breaker bar (with longer extension, if possible).
This can be done from above the engine, as shown on the diagrams.
Then you can slip the belt off the pulley. (from underneath the car)
(of course you will need to remove the splash shield first)
Installation is the reverse of removal. Be sure to follow the belt routing diagram.
Good luck!!
Note. I did not touch/loose any other bolts.(as explained in other forums).
Just turn the 19mm tensioner bolt (clockwise direction) to compress the spring inside the "Automatic belt tensioner"
The car has an Automatic Belt Tensioner.

How do you remove the belt tensioner on a Taurus or Sable?
Before starting any work around the serpentine belt, disconnect the ground cable from the battery just to be safe. The working space around the belt and pulleys is pretty restricted, so you you may want to unhook and unbolt the coolant expansion tank for better access.
While the belt is still in place, be sure you have an accurate diagram of the path the belt takes around all the pulleys and idlers. This will save you a lot of time and aggravation later on. If there isn't a diagram on the fan shroud, draw it out yourself.
To remove the belt, you first have to release the pressure from the belt tensioner itself. The manuals recommend using a 15mm wrench on the pulley bolt to rotate the tensioner arm. (Some older models have a square hole in the tensioner arm itself that fits a 1/2" drive.) If your engine is a 3.0L OHV (the most common), turn clockwise, towards the front of the car. If your engine is a 3.0 OHC, turn counterclockwise toward the back of the car. A deep offset box end wrench will work, but you may have to put a length of pipe over the handle end of the wrench to get enough torque to move the arm. A better choice is a serpentine belt tool, available from most automotive supply stores. It costs about $25 and is basically a long, flat breaker bar with an assortment of sockets and a 1/2" extension bar. Its low profile makes it easier to do the job without rounding off the bolt head, which is a danger with the "make-do" alternatives.
CAUTION: If the tensioner spring is seized, too much torque on the pulley bolt may round off the bolt head or even shear off the bolt. If the arm doesn't move with reasonable pressure, try gentle pressure with a flat prybar on the pulley itself, being careful not to damage the belt or whatever you're prying against.
With the pressure off the belt, slide it off one of the pulleys (the idler pulley is a good choice because it doesn't have ribs or a shoulder that may damage the belt. With the belt out of the way, removing the tensioner is a matter of removing one mounting bolt. Unfortunately, on some Taurus models, Ford chose to use a T50 Torx head cap screw for the job, so be sure you have the right bit because this isn't a place to improvise. If you round out the Torx head, you're looking at chisel and torch work.
The question doesn't state why the belt tensioner is being removed. If it's a question of bearing noise from the tensioner pulley, it's possible to replace just the pulley rather than the whole tensioner assembly. If the tensioner is seized, it may be possible to free it up and reinstall it, but be conservative. Carefully inspect the serpentine belt and the idler pulley, too. None of these parts are that expensive to replace but failure in service can cause extensive damage to accessories or the engine itself, particularly if the water pump doesn't operate, since the engine can overheat to the point of causing damage.
Installation is the reverse of the above, taking care to route the belt correctly around all the pulleys and idlers. Be careful not to over-torque any fasteners as you put everything back together.
Once things are back in place, look everything over again carefully. Make sure there is nothing obstructing the path of the belt or rubbing on any of the pulleys. Check the alignment of all the components and make sure the belt is centered in all the pulleys and idlers. The last step is to reconnect the ground cable to the battery, check that everyone is clear of the front of the car and start the engine. After it's been running a minute or so, do a visual check that the belt is running straight and true and that there's no obvious slap or play, or smoke that might indicate the belt is rubbing against something. Also make sure that all the pulleys are moving properly, and not seized. Take a test drive and be sure that all the components (alternator, power steering, A/C, and water pump) are working properly.
Your first step is to remove the washer/coolant tank assembly so you can get easier access the area of the tensioner and belt. Then remove the serpentine belt. I usually do this by inserting a pry bar into the tensioner casting and pushing down or forward to relieve tension on the belt.
Once the belt is removed, simply remove the center bolt from the tensioner housing. The tensioner will come right off.
If the idler pulley is noisy, but the tensioner is strong, you may want to just replace the pulley.
Change the belt too if it looks worn or old.
First remove the belt tension utilizing a serpentine belt removal tool available for purchase or rental at parts stores. Rotate the bolt on the tensioner clockwise on OHV, or counterclockwise on OHC engines, then remove the drive belt. Check both the tensioner and idle pulley by spinning. If replacement is needed, remove bolt and replace tensioner and idle pulley. Reinstall belt.
Put on a heavy pair of gloves and get a 2x4 piece of lumber. With your hands, pull up on the belt (this will take quite a bit of strength) bringing the weighted hup towards the front of the car. At this point slip the wood behind it to hold it forward. Now you can pull up again and slide the belt off the top pully, and you might need a screwdriver to get it started.
What size serpentine belt do I need to run a 2001 Ford F150 4.6L that would omit the ac compressor?
Buy a "by-pass pulley" and you can use the same belt.

What are the symptoms of a loose serpentine belt?
You will definately know when your belt is loose because you will hear a loud squeeking. When it comes off entirely you may lose power steering and other crucial functions.
This happened to me and I almost crashed head on into a semi, trust me, you'll want to get that checked out.
How do you replace a 2000 Neon drive belt tensioner?
I have personally followed this person's advice step-by-step, and it worked flawlessly.
The bearings of the serpentine drive belt tensioner pulley in my 2000 Dodge Neon were starting to go bad and a horrific grinding noise was coming from the engine compartment. After reading up on all the work that needed to be done (a local mechanic offered to replace it for $700), I decided to do a little searching on the Internet and I came across this web page.
http://chronoscender.freeservers.com/neonserptens/serptens.html
As stated in an update near the top of the page, the only thing that has changed over time is Napa now sells an OEM duplicate of the pulley, so you don't need to install the 6 rib size outlined in the instructions. The OEM replacement is around $30, as opposed to Mopar's price of $130, and it comes with a lifetime guarantee. To learn how to safely lift the engine out of the compartment without completely removing it, follow the link on the same page as above called Neon Timing Belt Replacement.
Also, make sure you stabilize the engine when raising it up. I lifted the engine using a 2 ton jack under the oil pan and it must have come up too tilted, because I ended up tearing the rubber insert of one of the motor mounts and had to replace the whole thing. In retrospect I think I must have missed removing the bolt of that mount before attempting to raise the engine high enough in the compartment to get at the plate the pulley is connected to.
That's all I have. Good luck!

How do you clean antifreeze off your 99 Ranger serpentine belt so it will quit squealing?
buy some belt dressing at autoparts store and just spray it on the belt while it is turning
What can you use to clean belt dressing off your belt?
The best way is to take the belt into a DIY car wash bay. Select the 'soap' option and use high pressure to clean off the residue from the belt, then use low pressure rinse to completely remove the soap. Allow to dry before re-installing.
Where to find serpentine belt routing diagram for Windstar?
- front, passenger side
- on top of the radiator housing
- On the passenger side shock tower
- On the bottom side of the hood - look up
- on the plastic panel above the radiator. There should be other information such as type of spark plug and gap and type of AC refrigerant and etc., there too.
See "Related Links" below
I had this exact problem yesterday. It was an '02 model also. Not a single diagram anywhere. I went to the local auto parts store and had them make a copy for me. You could also go to a dealership service department and if you ask real nice they will copy one from their book.
I went to Autozone and got a diagram.
Autozone.com also has the Chiltons Repair Guide for free - includes the serpentine belt routing & much much more.
I found that it is only tight one way. Just remember the two pulleys that don't have the grooves in them will be against the smooth side of the belt. It was a real bear , but we got er done.

How do you change the serpentine belt of a 2001 Chevy Malibu?
Jack up car and support the engine, there is a place under there that says put wood block here, don't let all the weight rest on this block though.Use tool to take tension off belt, fits in square hole on belt tensioner. Now you can loosen the motor mount right in the middle of the sepentine belt on the V6. Take off old belt put on new belt, redo/torque motor mount, put new belt on pulleys and tensioner, remove wood block.
You will waste time with the block and floor jack method!!! Read completely first!
This is easier and faster....First loosen only the LEFT BACK BOLT ONLY " ONE " engine motor mount bolt and remove it out completely - then turn the bolt back in 3 to 4 turns making sure enough bolt threading can support engine - next take out the RIGHT FRONT BOLT COMPLETELY to lower the engine. NOW - work and slide / position belt through the gap making sure belt rest centered between front and back bolt patterns. Next put RIGHT FRONT BOLT back in and tighten till resting on mount with gap still in place and enough bolt threading to support engine - NOW COMPLETELY REMOVE LEFT BACK BOLT ONLY and pull / work belt through - PRESTO! Put both bolts back in and tighten and cut off old belt and be careful not to get hit by the tensioner.
Now if you are ( I'll be Back - Dude ) Arnold Sw-ger? - This is easy for you! -- adjust tensioner with one arm and install belt. Please be sure first the new belt will be positioned through in proper convention.
Easiest way....
The belt will not fit between the motor mount. Easiest way is to jack the car up and put a cinder block under the motor and lower the jack down until the motor rests on the cinder block. Remove the motor mount and use a 3/8 ratchet to release the tension on the belt. There is a square hole on the tensioner pulley that the ratchet fits in.
How do you change a serpentine belt on a 1999 Dodge Caravan SE 6cyl 3.8?
Pull upon the belt and it will show you which way the idler pulley has to go to relieve pressure on the belt. Then pry it with a 15 mm wrench to relieve pressure and there should be a schematic under the hood to tell you how to route the belt. If it isn't there draw a schematic before you take the belt off. Don't rely on memory.
I put a ratcheting cargo strap on the 15mm wrench and secured the other end so as to pull the tensioner enough to easily slip the belt into place with both hands.
youll have to place a jack under the engine and then remove the mount
I have a 98 Buick lesabre limited and I changed the belt without jacking the motor or removing the motor mount. There is a slot about a 1/4" wide the belt slips through so you don't have to remove anything. After studying it for a little bit it is very easy!
Do not jack. The engine support bracket does not need to be removed. Only remove the lower bolt and spacer. (18 mm) regular socket will do the trick. One the bolt is removed, removed the spacer by wiggling it around. Place the belt on and then replace spacer and bolt.
I just did one this morning in less than 30 minutes.
First.. I drew a simple map of the belt before I began. Then I used a 15 mm on the tensioner, pushed it towards the firewall, slipped the belt off the alternator and gently released pressure off the tensioner.
NEXT.. There are two nuts on the MOTOR SIDE of the mount in front towards the radiator kind of but down in there by the pulleys. LOWER FRONT 18MM and UPPER FRONT 15MM. Remove both nuts.
Next remove both studs. THE VERY SAME TWO STUDS YOU JUST REMOVED THE TWO NUTS FROM. I used 2 tight fitting 6 point SOCKETS (I think 6 & 8mm) in place of the reverse Torx (star) sockets normally required for removal. BE SURE THEY WIGGLE ON TIGHT! Don't strip the edges or go buy the proper sockets. Mine were both barely snug and came right out with no Torx required.
Next there are two spacer tubes these same studs were floating through. If they have not already fell out a little persuasion should wiggle them out. Now there is room to slip the belt out and the new one in.
P.S. You may only need to pull one or the other and not both. I simply did both.
Also.. The lower stud only slid until contacting the passenger side frame. I remedied this by loosening the two big 18mm nuts pointing straight up at me on the center of the mount joint until they were just about out of threads. This barely lowered the engine enough for the stud to completely come out and the tube became loose on top of the crank pulley.
BE CAREFULL OF THE CRANK SENSOR BELOW THE LOWER SPACER! ITS RIGHT THERE!
Reverse order to reinstall. That's all
93 buick century can you bypass the airconditioning pulley on the serpentine belt?
Yes, at least on the 3.3l engine. You'll need a shorter belt. Just ask for the belt for the non AC equiped car. There should be a diagram of the belt run in the engine compartment, but if not, the run is the same, except where currently the belt comes off the top of the alternator, goes around the AC, then back up to the idler, it will just go from the alternator to the idler.
How often should you check the belts on any car?
You should check belts, hoses, fluids, wiper blades, lighting, tires and tire pressure at least every oil change.
Once every 3 months or 3000 miles. Which ever comes first.

Is there a serpentine belt tensioner on the 1993 lebaron 3 liter v6?
Well, there's a tensioner pole involved in the main belt, if that's what you ask; you can easily locate it as the pole that pushes down the belt on the top of the system, nearest to you that the alternator pole if you are seeing the car at front. If the tensioner pole is damaged, every new belt you replace will be destroyed by the engine in days. If I didn't answer you well or you have any more questions, please feel free to write at alg11@televicable.net.mx

Where can one find large belt buckles?
Belt buckles come in a variety of sizes and styles. Local accessories stores, where they sell belts, also sell belt buckles. They are also available at flea markets or online stores like Amazon.
What happens if you do not repair a squealing belt?
The squeeling is caused by friction between the belt and a pulley because it is not tight enough. In time, it will burn the area that is making contact and create a smooth polished surface so that you will never get enough tension to stop the squeel. Tighten the belt or replace it!
How do you tighten the serpentine belt located on a Toyota Sienna?
I also have this problem with a 2004 Toyota Sienna. It seems that when it is cool and/or damp, then I get a whistle or squeal from the serpentine belt. I have not been able to get anyone to confirm how to adjust the belt and have not yet found the Haynes or Chiltons manual for this newer model. I'm not sure if this is the proper procedure but I WAS ABLE TO TIGHTEN the belt a little. There are two bolts on the alternator and an adjuster bolt. The ones facing the passenger side at the top rear and bottom front hold the alternator in place. By loosening those, I could then turn the adjuster bolt at the front bottom of the alternator. Due to the angle of the bolt, I needed two long extensions and a swivel. It's quite a trick using the swivel and keeping the socket on the bolt. I will watch for a while and see if I continue to get the squeal. I found one other query posted on the web about this squeal problem and mention that the dealer was not able to fix it saying it was normal. More to come if I get any new info.
Thanks for any input anyone can give.
This worked fine for me on our 2000 Sienna. I just would add the adjuster bolt did tighten
in the usual direction -clockwise. 1/4 to 1/2 turn did it. I would say just turn enough to stop the squealing.
