I just replaced the serpentine belt on my 1996 Ford Contour. I opted to remove the front passenger-side tire to gain access to the tensioner. Once I was able to get to the tensioner pulley, I had the old belt off and replaced within 10 minutes. I did have some help, though. It is much easier to have one person release the tension while another puts the new belt into place.

No, you do not have to remove it. It is also possible to release the tensioner top-side. I once had a tensioner go bad in the parking lot at work and had to replace it there with what I had in my trunk. It is easier with the tire off, but if you have to a slim ratchet with a shallow socket should do the trick.
Check to make sure the belt is routed around the compressor pulley. Also check the wiring connector at the compressor in case it was dislodged.
No. The serpentine belt controls A/C, alternator, water pump, power steering pump, and that is it. And if the belt is replaced properly, it will not cause damage to anything.
The Tensioner is spring loaded-use a long wrench on the center of the pulley 2 release tension-DON"T UNBOLT anything-IF it doesn't feel springy then find the bolt in the center of a (the) pulley that is.
No, they usually can stretch slightly if anything but the tensioner should take up the slack if they do. If you took it off and when you go to put it back on it's too short you have routed it incorrectly.
You don't. The serpentine belt tension is automatically maintained by the tensioner pulley, which is an idler pulley located on the passenger side of the system and looks like it doesn't drive anything. If the belt tension is incorrect, the tensioner pulley must be replaced. If the question meant 'how to release tension from the belt' (for removal, etc.), this is done by applying the correct size socket wrench to the tensioner pulley's center nut and rocking the pulley away from the belt.
check the belt tensioner. the belt is used to activate things like your A.C., alternator and other things. the tensioner takes up the slack on the belt after its installed. it dosent DO anything except take up the belt slack.
You should be able to get at it with one of the special tools available at most auto parts stores - they are inexpensive, and look like a long, flat piece of metal with a 1/2" square drive on one end to engage the idler arm.
It is the same assembly as the tensioner pulley - the little pulley that isn't attached to anything.
if the 2000 is anything like the 99, the alternator is on the top in the front. Very easy to find. Pull of the serpentine belt (use the tensioner to help) and then you remove the electrical connections very simply. UUndo the three bolts connecting it, pull it off. Do the reverse to put the new one on...and slap the serpentine belt back on. Very easy process..hardest part was the belt, but you can do it.
Open the hood. Now look at all the pulleys. The one that is not connected to any component and is not driving anything, is the idler tensioner pulley.
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.
No specific problems other than it's pretty easy to install incorrectly which will ruin them pretty quickly. Also check the pulley on the tensioner. If the pulley is worn or doesn't turn freely, that will cause premature wear on anything with a serpentine belt. Good luck.
Generally, serpentine belt systems have a spring loaded tensioner pulley in them that don't require adjustment. However if your belt is loose, look for an idler pulley (one that does not drive anything). These will sometimes have an adjustment on them. A word of caution, serpentine belts require a specific tension that, if adjustable, require specialized tools to set them. Too tight and you will wear components driven by the belt prematurely, too loose and there can be problems with a component in the system. If you are a proficient do-it-yourselfer, I would suggest buying a service manual and following the proper procedures outlined in there.
You fail to list the make, model, year, and engine size of the vehicle you are asking about. Therefore I can only tell you to look at the belt. You will see one pulley that is not driving anything. That is the tensioner pulley.
There is not currently anything that is going to replace the Internet in 2014.
Belts which are at incorrect tension levels can cause a squealing, or if they are wet. This is often caused by a worn belt tensioner on its way out. If so, it will soon seize up, or come apart, leaving you stranded with a shredded or loose serpentine belt. The squeal can also be caused by a worn serpentine belt (lots of cracks in the underside), a worn steering pump, a worn water pump, a worn alternator (these usually whine rather than squeal), or anything else that turns, such as an idler pulley.
under the hood, the owners manual, a chiltons or haynes manual or at autozone.com A 2001 Honda passport is the same thing is an 2001 Isuzu rodeo. Isuzu made them and Honda bought and resold them under their own name. yes go to autozone if possible. if not maybe they can email you the diagram. They will also loan you the breaker bar. it makes it easier but you don't need one. it is simply a wrench or socket attached to a 2 or 3 foot handle for leverage. I think i used a 14mm wrench You need as much leverage as possible because it is very hard to push the tensioner pulley down.the tensioner pulley is right above the alternator pulley just left of center of the front of the engine. Route the serpentine belt everywhere except for maybe the idler pulley (a small pulley on top which doesnt run anything) and push DOWN or clockwise on the tensioner pulley. you do this by putting a socket or wrench on the bolt in the center of the tensioner pulley and push down or clockwise. this will give you the slack you need to slip the belt over the last pulley. Just make sure that the serpentine belt is in all the tracks fully. Anyone can do this!
It could be cracks in the serpentine belt, they tend to make a lot of noise if it gets very bad. It can also be bad bearings on the idler pulley or one of the other pulleys or even the alternator or water pump or for that matter, anything else that's driven by the belt. Pull tension off the serpentine belt by backing off the tensioner. Manually turn each pulley by hand and try to find one that grinds or feels "rough" when you turn it. If you find one (or more) that doesn't turn smooth, replace it.
You should have a belt routing guide on the radiator support of the vehicle when you open the hood, somewhere around the hood latch. You will notice a spring tensioner pulley under the alternator, you can use a socket or a wrench to remove the belt, turn the tensioner clockwise to take the tension off the belt to remove the belt. You do not need to remove anything other than the belt. Can be removed with fan shroud in place. Notice the belt routing guide while reinstalling. To install route the belt as in belt routing diagram, the tensioner will be the last pulley to put the belt over. Its a little easier to put the belt on the alternator last. Usually the wrench or socket gets in the way of trying to put the belt on the tensioner last.
There is a belt tensioner (spring loaded pulley that automatically keeps the belt tight) that needs to be temporarily slackened while the now loose belt is slipped off one of the accessories. Sorry, but I can't remember what tool is needed to loosen the belt tensioner. Just opening the hood and observing the tensioner is all that's needed. FYI: if you're having trouble locating the tensioner, just look for the only pulley that appears to drive no accessory, i.e., air conditioner, power steering pump, etc. . Before you do anything either draw a picture of how the belt goes or photograph it. If you don't GOD BLESS YOU. You can look up schematics but most are incorrect. Auto zone had the only correct one for my Rodeo. My belt broke and there was no diagram under the hood.
There is a belt tensioner at or near the top of the belt run area. It has a pulley on it and is spring loaded, plus it has a provision for a wrench to be attached or inserted into it. Simply use your wrench to release the tension and you will find it is easy to remove the belt. Before you do anything, observe how the old belt runs across the pulleys so you can replace it properly. I hope this helps you. Mark
This is actually a fairly straight-forward and easy job. I completed it in my garage in about 15 minutes. 0. Make sure engine is COOL. otherwise, you WILL burn yourself. 1. Take a picture or diagram the path of your existing serpentine belt. This is critical to getting the new belt on. While it will only "fit" 1 way, it is much easier knowing how to "snake" the belt around, in-between and under the water pump, alternator, a/c compressor, tensioner, etc... 2. the tensioner is the key. you will need the biggest ratchet (3/4") that you have and it is even easier with a "breaker" bar (long bar that increases your torque, with socket head on end). 3. The belt tensioner is (using a clock face) about 2:00 - 3:00 oclock from the main crankshaft pully (if you were standing in front of the car, looking through the radiator, at the front of the engine). It has a 15mm or 17mm nut on it's center. If you put a socket to it, the tensioner will move by applying pressure in the counter-clockwise direction. This is compress the spring insid the tensioner, it will move in and provide slack for the belt. 4. SO, snake the new belt into position except for going around the tensioner. 5. (This is a little tricky) With the belt "almost" in place, place the socket inside the belt and onto the tensioner nut/bolt, so that when you compress the tensioner, the belt will be able to slip onto the tensioner pully. Apply the counter-clockwise pressure to the tensioner, creating enough roon to slip the belt into place and in the correct grooves. Release the tensioner and you are done! I was able to replace my belt without removing ANYTHING from the front of the engine. If you must have the room you can remove the electric fan shroud by unbolting the two top bolts behind the radiator and disconnecting the two electrical feeds (on to each fan motor). The shrould will pivot back and lift out. It is easy, but not necessary to remove this item. Good luck!
If the '94 is anything like my '98. In order to remove the belt there is a belt tensioner underneathe the power steering pump on the drivers side. Crack the bolt loose on the pulley of the tensioner. If you look to the right of it and behind it you will see a longer bolt, you need to use that bolt to adjust your tensioner so that it lets slack on your belt.
No. It actually must remain in the car, because it is on the serpentine belt.
: If anything, try replacing the fuel pump relay (about $17.00 part) before you do anything too expensive. I spent about $1200 replacing the computer and the pump and finally replacing the relay worked. It almost looks like a fuse and should be possibly located under the glove box (at least it was on my 95). Good luck.
