First thing, if your belt seems soft or sloppy when you push on it or if it bounces at an idle. When you start/drive you will get a slight knocking sound between 900-1200 RPM that's the internal spring on the tensioner. To fix this you have to go to a dealer and get the replacement supercharger tensioner. The main tensioner in the back near the firewall is easy to find at auto zone or o'reilly auto parts. The idler pulley is a lot easyer to check. Take your accessory belt off of the idler pulley and try to move it, if theres ANY slop it needs to be replaced.

Serpentine belt replacement 2005 Toyota corolla?

what's the question? how to do it? specific to corolla or just serpentine belt in general? release tension on belt by: -put a socket/breaker bar or ratched on the tensioner pulley bolt and use it to relieve tension on the belt -slide belt off tensioner pulley. replace with new belt in same pattern across all pulleys and again relieve tension on the tensioner puller to slide the new belt back on --you may need to remove the bolt on the tensioner closest to the pulley (i don't know just judging by the picture i found) ---if you don't know what the tensioner looks like look up the part on autozone's website for a picture you can match on your car

Do know the size of the shorter belt on a 99 caravan with a 3.3 that bypass the ac?

There is an available bypass kit, but the belt is the same. You remove the ac compressor and install an idler pulley.


How do you change serpentine belt on 2003 Chevy Silverado?

first you need to be sure you know how the old one is routed, either by the diagram near the radiator or by making your own. there is an "inside" and an "outside" to the belt. next locate the tensioner pulley. its usually attached to the alternator. its the only pulley that isn't attached to/drive anything. put a wrench on the tensioner and slack the belt. remove the old one. compare it to the new one to be certain its the correct replacement. rout the new belt around all the pulleys making sure to insert the belt onto the tensioner last because you will have to slack the tensioner to get the belt on. pay attention to the way the belt "faces" each pulley.


How do you know if you have proper alignment of idler pulley?

Use a "straight edge" to make sure that the "valley" area (where the belt rides) is in alignment with the other pulleys


How much fan belt for 1995 Jeep Grand Cherokee Limited?

The fan belt that you need will be determined by your make and model and can be had by going to a reputable parts store and just telling them what you are looking for. You probably won't find a belt at Walmart types of places. On this forum you will find information about the belt tensioner pulley and how to change out the belt.....its an easy job but you need a ratchet and a socket of the size that will fit the nut on the front of the tensioner pulley.....you use the ratchet to release the tension on the belt so that you can slip the belt over the tensioner pulley, the last step in the process. Sorry, I don't know what size that socket is but the parts store may. By the way, the tensioner pulley is the only pulley in that mess that doesnt actually drive an engine device (such as the AC, fan, alternator etc). It is spring loaded and keeps the serpentine belt under tension so that all the other things work correctly. This is a job that anyone can easily do but it does help to have someone there to help you: one to push on the ratchet and the other to slip the belt over the tensioner pulley. Good luck


How do you replace timing belt on a 93 subaru legacy?

Take it to the dealer! It's not a job for the timid or any shop that doesn't know what they are doing. Make sure you get the idler pulleys and automatic tensioner replace along with the timing belt. If the bearings seize in those idler pulleys it will ruin the belt and in turn take out your engine.


How do you change the WATER DRIVING belt on a 6 cylinder 1998 Mercury Mystique?

Not trying to be a smart a&^ but if you do not know that it is called a "Water Pump", you probably don't need to try and replace the belt. But basically you loosen whatever the belt is driving in addition to the Water Pump. Alternator, A/C compressor, Or P/S Pump. This will loosen the belt and allow you to replace it. Tighten the device you loosened until you have about 1/4" deflection at mid-point of the new belt. If you have one a serpentine belt with an idler pulley, then it is under tension by means of a spring loaded idler. Remove tension from the idler pulley and then remove the belt. Reverse to replace the belt. Tension is automatically adjusted. Check the condition of the idler once the belt is removed. Noisy, or rough turning idler should be replaced. Pay close attention the the routing of the belt. Take a digital photo if necessary.


Idler pulley diagram for a 2000 freightliner?

Need to know if you have a Detroit, Cat, or Cummins engine in order to answer this. As for the idler pulley itself, it's pretty simple to locate - it's the pulley which only spins, and doesn't actuate a pump, alternator, compressor, etc. Removing it is as simple as loosening the belt, unbolting it, and installing it in the opposite order.


Do you need to know what the torque would be to find out if the idler tension pulley has to be torqued when you install the serpentine belt on a 1995 Oldsmobile Cutlass Supreme?

there is not a specific torque for the idler pully. tighten it up with a ratchet and it will not loosen up


How do you change a tensioner belt?

We need to know the year, make, model and engine size of the vehicle then we need to know if you want to change the belt tensioner or the belt or both.


How do you know when idler pulley is bad?

Normally the idler wheel will have a bad bearing and will make a lot of grinding noise and or vibrate big time! If the bearings go out all together you will know real quick like as it will most likely burn or rip the belt off!


How do you replace a serpantine belt in your Subaru tribeca?

before takin off the belt make sur you can locate the belt map on the hood or under the hood near radiator fan shroud(cover if the is no map label you can draw your own diagram of the pulley sysrem draw it as close as you can then draw the way the belt goes around each pulley look hard for a label it is drawn with multiple circles and a black band (your belt routing diag. there is usually one main spring pulley and tensioner that holds the belt a a specified tension automaticly. if you dont know which is you spring tensioner you can put on a glove make sure car is off grab the belt firmly and pull hard the belt will give a bit while you are pulling on belt stare at the pulley that is move back and forth this is your auto belt tensioner. look at the pulley and arm closely it usually has a squre to accept a 3/8 or a 1/2 inch breaker bar or retchet wrench if not equipped with said squre hole use a wrench to fit the bolt that goes through the pulley never take bolt off other end as this bolt will remove the tensioner a possibly the spring causing injury pull on tensioner until it springs and belt start to slacken unhook belt while still holding pressure on tensioner with other pull belt off a top pulley a slow release tension pressure noe unsnake belt remove run new belt according to map pay attention that the grooves are completly on your pulleys snake the belt until one top pulley is the only one left lift on tensioner this will give you the slack you need to pull belt over last pulley. release tensioner now go to every pulley and make sure belt is completely on pulley one tooth will cause belt to fly off or premature wear p.s always measure old belt to new belt or it will drive you nuts trying to put a smaller belt on also count the ribs any questions email good luck g i looked online and you will need a socket or box wrence to puul on yensioner another waay to locate is it is about 4 inch pulley with no belt groves and about 3inches away mounted is the round spring housing. just look up replcement belt tensioner online to give you a photo of what your dealing with


How do you change the serpentine belt for a 2005 Pontiac Sunfire?

In order to change the serpentine belt on a 2005 Pontiac sunfire you must first locate the idler pulley. You can do this buy finding the pulley that is attached to a steel arm about 6 inches long. These engines are transverse mounted meaning that you may have a difficult time locating this pulley if you do not know where it is or what it looks like. However if you can recognize the idler pulley you will need a long wrench or breaker bar. I believe the correct size socket or wrench for the pulley is a 15mm. If you are using a wrench position the wrench on the bolt so that the wrench is leaning as far to the front of the car as possible because you will need to push or pull it quite a ways towards the rear of the car to loosen the tension on the belt. Once you have accomplished this you can simply slide the belt off of the most readily accessible pulley and release the idler pulley. After removing the old belt be careful to route the new belt correctly. Incorrectly routing a belt could lead to severe problems. After routing the new belt around all other pulleys, pull the idler pulley back into position and work the belt onto it. This may be difficult as the belt will more than likely have a seemingly tighter fit than the old one. This is because the old one has been stretched out over time.


A pulley on front of motor is loose but i don't know the name of it it's right above the tension pulley?

If it does not drive anything it could be an idler pulley.


How do you replace a serpentine belt on a 1992 Plymoth Voyager?

I'm going to assume readers already know how to safely jack up a car and have a basic mechanical understanding of what parts and tools are and that the repair is being done by one person with no helpers. It's easier to do this repair if you remove the bottom plastic engine cover on the passenger side and the passenger side front tire. There are two idler pulleys for the serpentine belt. One is fixed and the other is spring loaded (tensioner). Use a 15mm wrench to push on the center bolt of the tensioner pulley and it will pivot releasing the tension on the belt. Slide the belt off a convenient pulley and release the tension idler. There should be a decal under the hood showing the correct routing for the belt, if not PAY ATTENTION to where it was prior to removal. Remove the belt and reinstall the new one following the routing instructions. When reinstalling the new belt, leave the slack near the tensioner pulley and reapply your wrench to the center nut again collapsing the tensioner and slip the belt over it and let it return to normal position slowly. Double check your routing and if it all looks good start the engine to test it out, if it's running smooth and the belt is staying seated and not making any noises then replace the bottom engine cover and passenger tire and enjoy your ride.


How do you install a serpentine belt on a 1996 Ford Wind star?

First you need to know the belt routing. This should be on a sticker attached to the underside of the hood at the front edge (if not then research it on-line...that is where I found it). Start the belt at the bottom crankshaft pulley then follow the routing schematic for all pulleys but the alternator. Grab a 15mm open wrench and insert it on the belt tensioner pulley bolt located at the back of the engine (the belt should be on this one). The belt tensioner is spring-loaded so draw forward on the wrench until ther is enough slack on the belt to push it onto the alternator pulley. Slowly let the wrench go back creating a tight belt wrap. If it is not tight than you missed a pulley or you have the wrong belt. Removal is the reverse.


Does a 98 Honda civic have an automatic belt tensioner on the Serpentine belt?

That I know of, there is NO serpentine belt, unless you are talking about the the Timing Belt (hardly serpentine, but anyway), it has a belt tensioner, not automatic, though.


CHow can you know if your pulley is bad or the entire tensioner assembly on a Windstar?

If the tensioner cannot put a full 'load' on a new belt (as shown by the wear indicator markings on the side of the tensioner) - it's likely the tensioner requires replacing.NOTE: some sources recommend replacing it at 60,000A bad pulley (bearing) would be making whining/screaming noises.See "Related Questions" below for more


How do you change the drive belt on 2004 Monte Carlo?

This is a fairly simple repair. Look around under the hood of your car for a "belt routing diagram." It's usually on the passenger side of the car. Use this to know how to route the belt when you replace it. Also, on this little diagram, there should be a picture of a pulley marked, "tensioner." Use this to locate your belt tensioner pulley. It should be a black pulley held in place by a metal arm. There is a bolt, going through the pulley. I believe it's 15mm. If you place a wrench on this bolt, you can use the wrench to create leverage, to move the tensioner. I belive it moves towards the front of the car. But, use this to relive pressure from your belt to remove it. Then, consult your diagram again to reroute your new belt. It's easiest to wrap the belt around all of the pulleys, except for the alternator pulley. Then, detenstion your tensioner pulley again, and flip the belt over the alternator pulley. You should be good from there. Before you start your car. Make sure the belt is seated well on all of your pulleys. Start the car. Let it idle for a minute or two. Keep your hands and tools clear of the moving belt, and look to see that the belt is moving well in it's path. Shut the car off, and check to see that the belt is seated well once more, and your done.


How to reset the serpentine belt tensioner - or change tensioner and pulley on Ford Windstar?

The serpentine belt tensioner / pulley is on the front of the engine, and part of the belt 'routing'.Its job is to put tension on the belt as it drives the other devices like the power steering pump, water pump, air conditioning compressor.It is an aluminum casting that mounts with a single bolt to the engine. The pulley is attached to the arm.There are a few ways to move / pry the arm inwards, thus releasing the tension on the belt for removing/installing: grab on the pulley bolt (15mm?) with a wrench, or some later models have an opening for a 3/8th socket wrench to attach to directly without a socket."Screaming"/whining that goes up and down with engine speed is a key symptom of a bearing wearing out - one of which of course is the tensioner pulley bearing.The serpentine belt tensioner / idler pulley is preset at the factory. If it is worn out, it will need to be replaced.NOTES:The belt is recommended to be replaced around 60,000 milesThere is a wear indicator (minimum vs maximum) on the face of the tensioner arm to let you definitively now when it's time to change the belt.To remove the tensioner and/or pulley:loosen the pulley bolt while it is still on the engine - it is easier this way than when the tensioner is off the engineloosen and remove the tensioner mounting bolt - try an 18mm socket first, it's the most common size.You can also just replace the pulley if that is the problem and save about $25.Price reference:Tensioner/pulley assembly - $40Pulley alone - $17-20I just replaced the alternator on my wife's 2003 Windstar. It may not be applicable to your 97. I put the car up on ramps because the tensioner is the bottom-most pulley, nearest to the passenger compartment and almost directly below the power steering pump pulley. You need a 13mm wrench. I had a helper (my wife) working topside to put the belt over the alternator pulley, etc while I took the tension out of the tensioner pulley. I had to use the full allowable travel of the tensioner in order to get the belt on all of the pulleys properly. A younger stronger person could probably do it by himself by leaving the belt off of the balance wheel until last. There are likely spring clips that could be removed from the tensioner and then replaced as the final step, but there's not much room and my way dodged some skinned knuckles. Hope this helps.The "official" way to release the belt tension is to rotate the tensioner about 110 degrees counter clockwise, and press a flexible metal leaf on its side into a holding slot. Doing this does away with the need to pull hard on the belt. On at least some pre-2002 Windstar models, this was rather easily done with a long screwdriver or pry bar because the tensioner and the front idler pulley were one unit. But on the 2002, Ford decided they should be 2, and moved the tension into an impossible-to-access from above location. On the 2002, you can't even get a socket on the tensioner pully bolt to rotate it that way, because there's less than 1 inch of clearance between the bolt head and the vehicle frame. You'll have to decide if it's worth getting under the vehicle to save some pulling effort.Follow serpentine belt to pulley that is not connected to any engine componentFollow the serpentine (drive) belt into the engine compartment. Now go down. See that pulley that is farthest away from the front grill? That is the tension adjustment pulley. Put a wrench on the center bolt (on the pulley) and apply counter clockwise force. This relieves the tension on the belt. I'd recommend a friend be present to place the belt while you are holding the pulley in the retracted position. Hope this helps.Remove the belt, and the tensioner pulley just unbolts. You will need a flat type wrench. Can be purchased at local auto store. If I remember correctly the bolt is a 15mm.All the way in the bottom back of the belt. It's easier to access it from under the car with a 13 mm wrench. If you're replacing it jack and support the car and remove the pulley (left hand threads) from under the vehicle. Then you can easily access the 3 mounting bolts. (The pulley has to come off to completely remove the bottom mounting bolt anyway) A long tensioner wrench does not relax the pulley enough to install a new belt from the top because of the AC, etc. hoses and the limited travel of the wrench. This is how I did it for my 3.8 engine, don't know about a 3.0 liter.pretty simple.. remove the serp belt by rotating the tensioner, then remove the bolt(s) the hold the tensioner inple. reverse to install. make a note of belt routing before you take it off, although there should be a sticker under the hood indicating belt routing.Addendum to above:Note that the location of the Belt Tensioner is noted incorrectly in the Ford factory service manuals. The BT is near the firewall. Loosen the bolt that holds the BT to the engine block, put a wrench on the BT pulley bolt and, using leverage, rotate the entire assembly upward to relieve the belt tension.If the assembly is too tight to move (mine was) thread a loop of 1" webbing around the BT arm, put a crowbar through the loop and heave. Make sure to avoid punching holes through things like your AC Compressor or manifold during this process....and I didn't find this simple at allYes - the pulley can be replaced as a separate part.When you purchase the replacement part, it should be pretty logical on how to replace it on the tensioner arm - just one nut/bolt.One note: you may want to loosen the pulley nut/bolt while the tensioner is still mounted to the engine - AFTER the belt has been removed!tensioner won't lose tension unless they are bad or the belt is worn out. you can't adjust the tension.


How to replace the serpentine belt on a Windstar?

Easier than you think . . .Forget the pry bar, the socket, or whatever other tool you might have been told to use. Position the belt on every pulley except for the alternator belt. Pull the belt toward the front of the van (this pulls the tension pulley) and wrap it around the pulley on the alternator. It takes about 5 seconds and does not require a tool at all.Answer:Notes:There are a few ways to move / pry the arm inwards, thus releasing the tension on the belt for removing/installing: grab on the pulley bolt (15mm?) with a wrench, or some later models have an opening for a 3/8th socket wrench to attach to directly without a socket."Screaming"/whining that goes up and down with engine speed is a key symptom of a bearing wearing out - one of which of course is the tensioner pulley bearing.The serpentine belt tensioner / idler pulley is preset at the factory.

All you need is a pry-bar about 24" long that could reach as far as the idler (towards the passenger wall within the engine compartment). The idler is the one that maintains the tension for the serpentine belt during operation.Next is to insert it on the back of the idler (note that there is a slot for it to go and lift down towards you. Your serpentine belt would become loose then your can remove the belt.Note: Please remember how the belt was wound from component to component as this is very important.Another option is to find a socket wrench mounted to a driver and same principle-apply a clockwise motion and the idler will be loosened.Very important: DO NOT DO THIS WHILE THE ENGINE IS RUNNING, K...Good luck.Tips:remember the two pulleys that don't have the grooves in them will be against the smooth side of the beltAnswerThe serpentine belt tensioner is spring loaded. It is the pulley located all the way back toward the firewall. Put a 15mm wrench on the bolt head in the middle of the pulley and leverage the tensioner to slack the belt and remove it.Answerif you're under the hood, look at all the pulleys. the big one in the back, that is the one you will need to get to. I am not well with the proper terms or even tools, however, when you go to tighten it, it will turn towards the front of the car. at that time, you can get the belt off. Remember the diagram of how it goes on, cause if you don't, none of your things will work. oh, buy a book also. it is faster than this forum.AnswerYou need to obtain a flat serpentine changing wrench. They come in a variety of qualities, but a cheapie will do ~10$. You hook that on the end of the sprung idler pulley and rotate against the spring pressure. the belt will loosen, pop it off, and put the new one on. The whole process will take under 10 minutes once the old belt is off. I considered cutting it off, but didn't need to with the wrench. Without the flat wrench, you will fight this for too long and likely not succeed.AnswerI couldn't find a flat serpentine wrench (breaker bar) - the local stores used to carry them. What works just as well is a 15 mm box end wrench (the circular type that encloses a bolt), with a set of vise grip pliers for torque. The wrench is offset just enough to be able to place on the 15 mm bolt of the automatic belt tensioner pulley. Rotate the wrench clockwise (toward the front of the car) to release the pressure on the belt.AnswerA small rope on the end of the 15MM wrench will hold the tensioner or a helper can pull on the rope.AnswerI labored with this one for quite a while, searched the internet, and then someone at work told me the secret.To remove the tension, take a box-end wrench and place it on the pulley bolt. Then use the wrench as a lever (like you are tightening the bolt) and pull toward you. The arm of the tensioner will come toward you (it rotates around the bolt which holds the tensioner on the engine). Remove the belt. If you want to remove the tensioner and/or pulley, loosen the pulley bolt while it is still on the engine (it is easier this way than when the tensioner is off the engine), then loosen and remove the tensioner bolt. Now you can replace the tensioner. You can also just replace the pulley if that is the problem and save about $25.AnswerIt took me four hours to replace the belt on my Windstar...First, take several pictures of the left side of the engine, getting as much of the belt as possible. You'd be surprised how quickly you can forget how the belt is wound around the pulleys and alternator. I'm glad I did, because the guys at the parts house gave me the wrong pattern. I wasted an hour because of their mistake!!!!!The belt runs around a tensioner arm located near the firewall toward the bottom of the engine (by the pass. side front tire). I'm not an auto mechanic, so I don't know the technical term. This is spring loaded and puts tension on the belt. Spray this arm with a boatload of WD 40 'cause you'll need it to move somewhat freely.Take the old belt off and put the new belt on, starting at the flywheel and around the tensioner and all the other pulleys except the alternator which is at the top of the engine. Squeeze the belt at the tensioner, pull the belt towards you, creating some slack in the belt and try to wrap the belt around the alternator.This is the best I could explain it. It's not that easy. You may be better off getting a new tensioner because the old one might be frozen up too bad.Good Luck!AnswerPurchase a serpentine belt wrench. They are a long flat looking wrench from a local auto store. There is a belt tensioner in the rear of the engine. Place the wrench on the tensioner pulley, and pull the wrench toward the front of the engine. This will loosen the belt. Install the belt around the crankshaft, and all other pulleys, excluding the alternator pulley. Hold the last bit of the belt in your hand, and then pull the tensioner toward the front of the engine again, and slip the belt onto the alternator pulley.AnswerAnd for a 2002 Windstar (3.8L).The tensioner pulley was at the back near the bottom. (If you look at a serpentine diagram, it would be at the bottom left.)To release the tension, you have to get a 13mm wrench around the bolt in the center of the pulley and turn clockwise. Space is very tight (no room for a socket), so I recommend using a serpentine tool with attachable wrench heads. AutoZone loans them out for free (deposit required).AnswerActually, the info from the linked question was not correct for a 2002 Windstar (3.8L).The tensioner pulley was at the back near the bottom.

Space is very tight (no room for a socket), so I recommend using a serpentine tool with attachable wrench heads. AutoZone loans them out for free (deposit required).Removing serpentine belt on WindstarYou will need a 1/2 inch drive breaker bar. Look on top front of radiator you will see a winding diagram for replacing the belt also. The tension release pulley, located just below and in front of alternator, has a 1/2 slot in the center of pulley. Insert the 1/2 inch breaker bar in middle of tension pulley and pull up, tension will be released.Reverse procedure to reinstall.- DarrellAnswerTo install:Install the drive belt over all the pulleys, other than the drive belt tensioner.Rotate the drive belt tensioner clockwise, using a 15mm socket or wrench, then install the belt over the drive belt tensioner pulley.Make sure that all of the V-grooves make proper contact with the pulleys.AnswerWell it's probably the same as the 1999 Windstar, so if it is: you need a 13mm key. It's better to have 2 people for this job: one underneath the vehicle with the key and one under the hood to remove the belt.If I remember correctly you torque frontward and the belt will release . Hope it can help!By the way, my van does not have the serpentine belt diagram sticker, so be sure to take a look if you have one, and if not, take a paper and mark the location of the belt through the different pulleys before removing the old one.See "Related Questions" below for links to online sources of belt routing diagrams.AnswerI have successfully changed my serpentine belt on my '96 Windstar. After fighting the tensioner nut my neighbor grabbed a pry bar and put it in the notch on the other side of the nut and belt it very easily moved the pulley down and relieved the tension and slipped the belt off. Leaving the bar in place and letting it pull backwards he rested the pry bar against the car while we put on a new belt. Pulling forward again and slipping the belt back over the alternator for the final touch. Forget the wrenches this was so simple I should sell the answer.AnswerFirst, buy the correct belt, then look on the fan shroud which should give the route that the new belt should take. I'm my 95, it didn't, but the only thing I was doing was replacing the alternator, so I still knew how the belt went. Then release the belt tensioner nut, which is 18mm and hard to reach. Release this nut a few turns, then the tensioner will slide toward the side of the car, and the belt should fit on. To re-tension the belt I am considering buying a tensioner tool, which is a long handled lever for $35.00. If you need a diagram, email me.AnswerFirst of all, you will need to locate the drive belt tensioner and the drive belt tensioner pulley. There should be a belt routing map under the hood.If you have a 6 cyl 3.0L engine: the drive belt tensioner is located between the crankshaft pulley and the water pump pulley and the drive belt tensioner pulley is located between the alternator (or generator) and power steering pump.If you have a 6 cyl 3.8L engine, the drive belt tensioner is located at the very back of the engine (if you follow the belt back from the alternator, the first pulley you come to will be the drive best tensioner) and it's very inconvenient to get to. The drive belt tensioner pulley is located between the alternator and the power steering pump pulley.Per Chilton's manual, use a 15mm wrench on the bolt of the drive belt tensioner and rotate the tensioner clockwise to release the tension. Remove the belt from the drive belt tension pulley. When installing the new belt, make sure that the drive belt is routed correctly and note the position of the indicator mark on the tensioner.Note: A standard belt tensioner tool will not get the job done. Ford may have a special tensioner tool for the Ford Windstar, but I haven't found one. I used a non-angled 15mm 6pt box end wrench (longest one I could find) and used a section of galvanized pipe to slip over the wrench for leverage and was able to release the tension to change the belt.AnswerJust replaced alternator on my 2002 Windstar. Found easiest way to loosen belt tension was by jacking up(and installing stands) front of van and having skinny son slide under. Could loosen tensioner for removal and re-installation with a **13mm**combination wrench and some grunting. Also, prior to loosening belt, I taped belt to all pulleys wherever I could reach them. That way the belt stayed in place.AnswerMy brother has a 1998 ford Windstar 6 cyl 3.8 engine. The drive belt tensioner broke. so He got a new replacement. He tried to put the serpentine belt ALL BY HIMSELF with no avail. just before he gave up. he call me. here is what we did: He installed the new drive belt tensioner using a 18 mm wrench without fully tighten the bolt. We routed the belt correctly (following the belt routing map under the hood). only leaving off the alternator pulley. now the only thing left was to put the alternator pulley. this was accomplished by us working simultaneously. while I grabbed the belt close to the tensioner and pulled it with all my strength toward the alternator to relief the tension ; my brother using both hands put the belt around the alternator pulley taking advantage of the loose belt. Once the belt was in place; He tightened the 18mm bolt fully. Mission accomplished.**New Edit: Added to above - on a 1999 Windstar with 3.8LI just did a similar method, but I just wrapped a small rag around the old belt and pulled towards me (front of van) until it was loose enough to pull the belt off the alternator. The I removed the belt from the rest which takes a little bit of twisting and using a flashlight to see where it may be hung up on. Then I put in the new belt around all pullies except the alternator at which time I had my wife come over and carefully place the belt while I pulled on it again.*This ended up being about 20 minutes total time.--------------------------------------------------------------------New EditFor my '98 Windstar 3.8 liter, the first issue is that the picture in the service manual pointed out the idler pulley as the Belt Tensioner; the BT is actually nearer the firewall. I loosened the bolt (18mm) that secures the BT to the engine and the BT pulley bolt(15mm) but was still unable to move the BT in any way.I then put an ~8" loop of 1" webbing around the BT's arm, slid a crowbar thru it and using the top of the strut housing as a fulcrum, lifted the crowbar. The BT shifted and I was able to reach down with one hand and remove the belt from off the idler pulley.First, note that there are significant differences between the 2002/3 and previous model years when it comes to the location of the belt tensioner and belt routing.For 2002 3.8 engines, the belt tensioner is below the power steering pump, below the passenger compartment air intake duct. Unfortunately, this makes it almost impossible to access from above the vehicle. If you can raise the vehicle, you may be able to access the tensioner from below (see final note at bottom of this post).Here's a procedure I've used:1) Disconnect the negative battery cable.2) Draw a diagram of the belt routing--I believe there are as many as 5 belt routings for various Windstar years and models.3) With heavy gloves on, pull up and forward on the belt from the top of the engine (grasp the belt between the alternator and the power steering pump).4) With the slack produced from #3, slip the belt off the small alternator pulley, taking care to not pinch your fingers while you're pulling on the belt.5) Work the old belt off all pulleys and discard.6) Route the new belt according to your diagram from #2 so that it is properly aligned on all pulleys, and riding in the grooved pulleys EXCEPT the alternator.7) Now, again pull hard on the belt to compress the tensioner, and slip the belt over the alternator pulley. Again, be careful to not pinch you fingers.8) Reconnect the negative battery cable.9) Have an assistant crank the engine while you observe the belt travel. Make sure the belt is running fully engaged on all pulleys. If something amiss, you may have to repeat the proceAnswerNOTE: The "official" way to release the belt tension is to rotate the tensioner about 110 degrees counter clockwise, and press a flexible metal leaf on its side into a holding slot. Doing this does away with the need to pull hard on the belt. On at least some pre-2002 Windstar models, this was rather easily done with a long screwdriver or pry bar because the tensioner and the front idler pulley were one unit. But on the 2002, Ford decided they should be 2, and moved the tension into an impossible-to-access from above location. On the 2002, you can't even get a socket on the tensioner pulley bolt to rotate it that way, because there's less than 1 inch of clearance between the bolt head and the vehicle frame. You'll have to decide if it's worth getting under the vehicle to save some pulling effort.AnswerTo replace a worn belt, locate the idler or generator pulley.Loosen the hold-down fastener for the idler or generator pulley.Pry the idler or generator pulley inward to release the belt tension and remove the belt.Match the old belt up for size with the new replacement belt.Observe the belt routing diagram in the engine compartment.Install the new belt over each of the drive pulleys.

You will get plenty of slack and keep all of your fingers.AnswerAn answer is found in the linked questionI have a 2002 Windstar, and in it there is a belt tensioner pully (which swings on an eccentric radius) that tightens the belts around the other pulleys on the front of the engine (not front of van due to transverse mount). This is accessed by elevating the vehicle passenger side near the front axle (like you would if removing the front right tire) and above the front axle near the top of the fender wall is this pulley. If looking at the engine under the hood, it would be near the fire wall down by the fender. Once located then use a 13mm wrench (box end preferably) to swing the tensioner pulley toward the front of the van. This will loosen the belt where it can be pulled off the pulley. Make sure you use place the wrench where adequate swing can be achieved. follow the pattern of the existing belt for the replacement of the new one. If the belt has come off, simply find a diagram, or go by the pulley grooves or flat to understand which side the belt goes. Mine was broken, so I had to do that. It was easier for me to start from the top under the hood but leave the alternator pulley as the last one to wrap over (I did this with help, as I had the pulley swung, someone else wrapped the belt over the alternator pully).I hope this help...Be blessed in Christ >blueletterBible.orge-Sword.netAnswerYou need to use a socket wrench.There's a square hole behind the tensioner (You need to get under the car) and get the socket wrench and fit the head into the square hole.You will also need some hollow steel tubing to place over the wrench handle for use as a breaker. You will need this for leverage to get enough clearance to fit the new belt on.Answerpully is at the back of the engine,to left of the coil pack,a 15mm wrench fits the bolt,pull it toward you 2000 Ford Windstar - You'll need to put the car on jack stands or secure ramps. Find the tensioner by pointing a flashlight into the engine compartment just to the rear of the alternator pulley. Then slide unde the car next to the passenger side wheel. The bolt on the tensioner is 12mm. You'll need to use a box or open end wrench. Turn the wrench counterclockwise to take the tension off.To replace a worn belt, locate the idler or generator pulley.

Start the engine and check the belt for proper operation.Well it's probably the same as the 1999 Windstar, so if it is: you need a 13mm key. It's better to have 2 people for this job: one underneath the vehicle with the key and one under the hood to remove the belt. If I remember correctly you torque frontward and the belt will release . Hope it can help! By the way, my van does not have the serpentine belt diagram sticker, so be sure to take a look if you have one, and if not, take a paper and mark the location of the belt through the different pullies beforeremoving the old one.
