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 do you replace a serpentine belt on a 2000 Infiniti QX4?
On the 2000 QX4 you will have 3 belts. Starting from the fan blade back to the engine block, look to the left of the fan blade. There will be a tension pulley which looks like a smooth wheel with no pump or motor behind it. Release the lock on it by loosening the bolt in the center of the wheel (just until the bolt becomes loose or can be turned by hand). Above and slightly behind it is a bolt facing down that moves the wheel up or down, creating the belt tension. Loosen this bolt until the belt can be slid out. Next is a similar set up to the right of the fan blade. This will control the pulley for the 2nd belt. Finally, crawl underneath for the power steering belt (the last belt). Remove the black splash-guard to get access. Looking up on the pump, there will be 2 bolts. The one on the left, conveniently placed against the firewall, and one on the right, which mounts the p/s pump bracket to the engine. Break the tension on the right bolt so the bracket can move up and down, then tighten the bolt on the left (which commonly can be turned about 1/16 of a turn because of it's location - be patient!) Tightening will push the pump towards the engine, allowing the belt to be slid off. Replace the belts and manipulate the nuts in the reverse order of removing, inspecting that they're on the pulley correctly and in the correct place. Replace the splash-guard.
Note: When removing the belts, many of the bolts may be very hard to begin turning. Once you have broke the tension on them, they should turn relatively easy. Once you've broke the tension on the binding bolt (the center of the two pulley wheels and the bolt closest to the engine on the p/s bracket), the belt tension bolts should turn easily. If the belt tension bolts become difficult to turn, consider loosening a bit more to the opposing bolt which might be putting tension on the bracket you're moving or checking that you're not tightening the belt.
Tools required: You can complete the entire job with a metric 10,12,14 standard depth socket with a couple extensions. Also have a 12 and 14 open end wrench.
How do you replace a serpentine belt on a cadillac deville 1994?
Probably one of the most simple maintenance jobs a do-it-yourselfer can perform...
The only tool needed is a 1/2" breaker bar. To the rear of the power steering pump you will see a belt tensioner that has a square cutout that the breaker bar fits into. Pull the breaker bar towards the front of the car (or up) and the tensioner will move so you can pull off the old belt. Pay attention to the routing of the belt--make a diagram if the decal is missing from the underside of the hood! Put the new belt in place, use the breaker bar to again move the tensioner and slip the belt under it. You're done! Takes all of maybe ten minutes.

Why is your fan belt squealing?
The accessories on the engine cause alot of torque to be placed on the belt. When you first start the car the device whos belt is loose wont be up to speed and the belt spins causing it to squeal. Same thing if you are at a stop sign and step on the gas to go. The engine speeds up but the devise has to catch up. This is usually a quick fix and one person can do it. Some cars have a belt tensioner built in and it only takes a few turns to fix it. Others require a little longer but I havnt found a hard one yet.
Why does your 96 Saturn squeal after you replaced the belt?
If you're certain that the sound is from the serpentine belt you should check the belt tensioner. A weak tensioner spring will result in slipping and a noisy belt.

How do you put an alternator belt on?
On most alternators there is an adjusting bolt and a pivot bolt , both bolts must be loosened slightly to enable you to move the alternator , After the two bolts have been loosened , move the alternator ( toward the engine to loosen the belt ) (away from engine to tighten the belt ) You might have to move other belt driven components in the same manner as for the alternator Install belts adjust tension on belts ( It will often be necessary to use some sort of prybar to move the components while the belt is adjusted ,If this must be done to gain the proper leverage , be careful not to damage the components being moved or the part being pried against . ) Belt tension of each belt is checked by pushing on the belt at a distance halfway between the pulleys ( push firmly with your thumb and see how much the belt deflects ) A rule of thumb is that if the distance from pulley centre is between 7 and 11 inches the belt should deflect 1/4 inch , 12 to 16 inches 1/2 inch . A serentine belt ( the tension is controled by a tensioner ( loosen tensioner replace belt ) For better installation instructions go to the libary and check out a book or buy a Haynes Repair Manual for your make , year of car hoped this help you out

How do you install the serpentine belt on a 2002 Firebird?
if you cant find a routing diagram for the serpentine belt under the hood take a cell phone picture of it so you know how to route it once its off.
Usually you can use a 15mm socket or wrench and relieve the pressure of the tensioner by putting the wrench on the bolt that is at the tensioner wheel and pulling back, to find the tensioner if you don't know what I'm talking about, start the car open the hood and look for something that looks like it is holding the belt tight, usually this tensioner has some slight vibration to it and the wheel is nice and smooth since the back of the belt rests against it, not the grooved side.
How do you change the belt tensioner on a 96 Corsica?
I don't know if your 96 is the same as mine, but I just did this job on a 95 Corsica with 3.1 V6. On mine, I had to lower the engine to get at the bolt holding the tensioner on the engine.
Required tools:
- Hydraulic Service Jack (3-ton minimum recommended)
- 2 jack stands
- 2 tire chocks
- wrench or bar capable of releiving pressure on belt tensioner
(I used 15mm open ended wrench)
- 2'long 2x4
- 6"x10"x3/4" piece of plywood.
- standard metric socket/wratchet set for small fender bolts (<8mm)
all the way up to 15 mmm engine mounting bolts.
1. Set rear brake and chock rear tires
2. Loosen lug nuts on passenger side front tire.
3. Lift and support front of car on jack stands. I recommend placing them beneath front tires, under the jack notches, at the lowest heights.
4. Remove tire and mud guard(s) to expose the lower pulley assembly. You should be able to see the front crank shaft pulley wheel with the tensioner assembly located to the left.
5. Loosen the serpentine belt and slip it off of the alternator. Leave the belt on the car unless it absolutely needs replacement (A separate job that possibly requires removing a different set of bolts and mounts than what is described in step 9).
6. Use hydraulic service jack with sufficient lift (despite the fact that the car is already on jacks) and support to reach the oil pan, raise the engine 1-2 inches, and, most importantly, support the engine while you lower it in step 10. I used a $70 3-ton service jack from Wal-Mart. Anything lighter and cheaper probably won't work.
7. Place plywood between the jack head and the oil pan and raise the engine 1-2 inches in order to relieve pressure of engine mounting bolts.
8. Wedge a wood 2x4 (approx. 2' long) behind the alternater. This will allow better access to the tensioner bolt by keeping the engine from rolling towards the firewall during step 10, and it can be used as a pry bar to help realine the these bolt holes during reassembly.
9. Remove the three 15 mm bolts from the engine mounting bracket closest to the pulley assembly. On mine car there were two in back and one in front.
10. Slowly unscrew service jack handle and watch the passenger side of the engine lower. Let it down very slowley until you can see/get to the tensioner bolt. Retighten the jack handle. If you are not going to block the engine at this heigth and will only rely upon the jack to hold the engine while you replace the tensioner, DO NOT GET UNDER THE ENGINE FOR ANY REASON (you should not need to anyway).
11. You should now be able to see the tensioner bolt. I used standard socket with ratchet and 4" extender. If angle is extreme, you might need to use a swivle. Also, you might also need to unclip the coolant hose from its fender brackets and lower it or pull it back to improve access the the bolt.
12. Remove and replace tensioner.
13. Reroute serpentine belt around the tensioner and all other other pulleys except for the alternator.
14. Do reverse of steps 10 - 1. JOB COMPLETE.
How do you tighten the belts on a 1992 Geo Tracker?
The belts on the '92 are the same as any other car for the alternator and it is easy. Loosen the main alternator bolt that holds the alt. to the block. DO NOT REMOVE IT! Loosen the small bolt near the top of the alternator, lean the alt. into the block and remove the belt. Put it in a place that you will know which one it is, they are almost the same size! Then remove the power steering belt in the same manner. You will have to loosen the bolts from the bottom and utilize the round holes in the pulley for your socket, as well as from the top side for the tensioning bolt. Set THAT belt in another area so you don't mix them up. I don't have AC, so I assume that the belt for it is similar. They can be a bear getting them over the fan, watch your knuckles! Once you are sure of which new belt is which, install each belt in reverse of the way they came off. I tension the belts with a large screwdriver against the block, using it as a lever to make the belt have about 1/2" movement at the middle point in the belt. Tighten the alternator top bolt first, and then the block bolt. The power steering belt is more difficult, but follow the step to remove it in reverse. AC belt, the same as you took it off in reverse.

No need to remove the engine mount. You are able to remove the right. front lower motor mount bolt and sleeve though the wheel well. Just turn the wheels far to the right, remove belt from alternator with tensioner, remove the plastic inner cover in the wheel well and use two long extensions on a breaker bar to remove the lower bolt only on the motor mount. Pull the bolt out and remove the sleeve next to the engine. With the sleeve removed you can install and route the new belt. Reinstall sleeve and bolt.
