Inspection
Start by inspecting the existing belt, motor, fan and pulleys. Check to be sure the original belt's groove size fits the pulleys, and make sure the bearings, shafts and set screws are in good condition and secure.
While you're at it, inspect the motor mount, the fan and housings to be certain they will remain in good working order after the new airflow is set and that the equipment will be able to operate long term. We've all serviced equipment, only to have it die an awful death a short time later. Nobody's happy when that happens, so look past the new belt.
Record the old belt number written on the exposed surface of the belt. This is your best reference to find the original size, type, and length of the belt. If you don't have the replacement belt on your truck, these numbers come in handy for the inventory crew to verify your measurements by cross-referencing the belt number with the manufacturer's catalog. A faded page in a manufacturer's catalog is more accurate than field belt and pulley measurements any day.
Do the Math
Now it's time to use the "other tool," a math formula to determine the size of the replacement belt. Work the formula a few times before you try it in the field, just so you're familiar with the math. Practice makes perfect.
Several measurements are required to complete the replacement belt formula. Measure and record the distance between the motor shaft and the pulley shaft, and then measure the diameter of the motor pulley (also called the drive pulley or sheave) and the fan pulley (called the driven pulley).
Apply the following formula to determine a new replacement belt length:
Belt Length = 2C + 1.57 x (D1 + D2) + 1-in.
Where:
C = The distance between the motor and fan shafts
D1 = The diameter of the small pulley
D2 = The diameter of the large pulley
The math is quite easy; it simply includes adding and multiplying. Here is a completed formula to walk you through the steps.
Example:
C = (12-in.) distance between shafts
D1 = (3-in.) diameter of the small pulley
D2 = (8-in.) diameter of the large pulley
New belt length = 2C + 1.57 x (D1 + D2) + 1-in.
2(12-in.) + 1.57 x ( 3"+ 8" ) + 1-in.
24-in. + (1.57 x 11-in.) + 1-in.
24-in. + 17.27-in. + 1-in. = 42.27-in.
So, select a new belt the next length above 43 inches.
Next, determine the thickness of the belt. This is determined by measuring its cross-section. Be careful; old belts may be so badly worn that the dimension may not be accurate. State the new belt size by stating its length and its cross section nomenclature (Click here to view a chart which shows typical HVAC belts and measurements.)
the belt tensioners are on the alternator and the air conditioner. On the alternator, you would have to loosen the 2 bolts that are on the tension bar. On the air conditioner, you would have to loosen the tension bolt and you would also have to loosen a bolt that is behind the air conditioner pulley. You would have to turn the pulley to get the holes to line up to the bolt to loosen.
write down how the belt is currently installed loosen the tensioner with a 15 mm socket it is the last pulley on the far bottom left you must remove the passenger wheel and splash guard to get to this pulley after you loosen the pulley pull the belt off put on the new one in the same order i go over the alternator last usually make sure the belt is on all pulleys tight and off you go it is easier to get the belt on with 2 people time .5 - 1 hour
1) Rotate drive belt tensioner mechanism upward, away from drive belt using a 1/2 inch breaker bar. 2) Remove serpentine drive belt. 3) Reverse procedure to install.
Most cars and trucks today have what is called a serpentine belt which runs most accessories.They are very dependable and usually easy to replace. To decide if your belt needs replacing, simply look at the grooved side of the belt to see if it is cracking badly. A couple of cracks every 3 inches is normal, but if you see cracks every 1-2 inches I would recommend that you replace it. On most cars and trucks the procedure is basically the same. First off, get the correct belt by bringing your cars VIN number to the parts store(located on your cars dashboard) the parts store may need it. If there are two choices, get them both so you can complete the repair. Once you have the correct belt, take a minute to review how the belt runs across the pulleys and also check to see if your car/ truck has a underhood diagram of belt routing in case you need it. In most cases you will need a socket wrench or breaker bar with either a 3/8" and /or 1/2" head on it and possibly a short extension. Some models may require a wrench of these similar sizes.Now that you are ready to go to work, you will need to find the spring loaded tensioner which is generally located near the top of the belt path; it usually has a shinny pulley on it. Look at the tensioner and insert the tool into it and apply opposing pressure to release the belt.Now, simply install the new belt making sure it fits into the grooves on all the pulleys. Start the car to check it and you are done and you saved yourelf some money!
it means you need a new belt...plain and simple....lots of people keep driving on their cars when a belt squeaks..and allit does is lead to other problems..... i am no expert, but i think it is the Drive belt that is squeaking
If your vehicle has an automatic belt tensioner with a serpentine belt, the belt is worn and needs to be replaced. On older models, the belt tension can be set by adjusting it at the alternator bracket. Loosen but do not remove the two bolts that hold the alternator in place (one at the bracket and one on the block) and pull the alternator to tighten the belt. Hold in position while re-tightening the bracket bolt then tighten the bolt on the block.
http://www.focushacks.com/index.php?modid=75 The link above will give an indication on how to proceed. However, be aware that the 15mm nut on the automatic belt tensionner must be turned counterclockwise to release the tension on the belt. Not much torque needed when correctly performed. When working from above the belt should be monted on all flywheels except the idler pulley. Whilst turning the belt tensioner (counterclockwise) push the belt down under the idler pulley and release the torque on the tensionner nut to complete the installation.
It depends on whether you have the self-adjuster or not. Without the adjuster the steering pump needs to be loosened at the three bolts that hold the pump to the bracket. The bottom bolt is the tension adjuster. With the self-adjuster, you need to rotate the adjuster towards the engine to slip the belt off. Once the belt is off the tensioner it will move out of the way. Be prepared to use a block of some type to hold the tensioner so it won't hit the battery case. The nut on the tensioner is a 15mm size
Also, once you have the belt off, be very sure you put the new one on the right way. There should be a sticker on the engine cowl that shows you how the serpentine belt should route around the engine pulleys. Once you have it routed right, make sure you tighten everything very tight, making sure you have put enough tension on the belt. This is usually a tough part of the process because you need to get the tension against the adjusters, which keep the belt tight as it moves
Hey Duane==I think I use a wrench on the bolt that holds the pulley to the bracket for the idler. I think it is 13mm. Goodluck, Joe
There are 7 pulleys to put it over or under on the 4.0. The ridged side of the belt goes on the ridged pulleys, the smooth side of the belt goes on the smooth pulleys. The ridged side is 'inside' the loop made by the fan. So starting on the left (facing the truck) The upper left corner pulley (AC Compressor) OVER Directly under that, low, the alternator UNDER OVER the fan UNDER the motor INSIDE the tensioner OVER the power steering pump UNDER the water pump Another way to put it: So the two large, center pulleys are the water pump and the motor. It is on the bottom of both of these. The top two on left and right, respectively are the AC Compressor and the power steering pump. it is on top of these. The remaining two pulleys are on the left; a small one low is the alternator which the belt runs on the bottom. The other is the fan which the belt runs over the top. Make sure the tensioner pushes the belt IN TOWARD THE WATER PUMP as you tighten it.
The diagram for replacing a serpentine belt for the 1991 Jeep Cherokee Laredo is located on the front of the vehicle inside the engine compartment. You can also find this diagram in the Chilton's manual for this vehicle.
most auto parts store carry manuels on most cars just find the one that is on your van and a diagram of how the belts go on will be in it. the books cost around 15 dollars to buy but some store will let you look at them.
If you've got a 4.0 litre engine than you've got a Automatic belt tensioner on the engine. Sits to the right of the alternator. If your belt is loose, than you need to check that the belt is on properly on all the pulleys, or if you have the right belt. If the belt was made for a motor with A/C and yours doesn't have that, then the belt will be to long. Check with your local auto part supply store. Hope this helps...... For info on how to route the belt, get a chiltons manuel and it will have a diagram.
The alternator, water pump, power steering pump, air conditioner and possibly the air pump receive power from the serpentine belt.
The belt is held in place by a tensioner. it looks like a flat pulley with nothing attached.it has a nut on top that is used to release the pressure on the belt. It is a good idea to get the tool that is needed to do the job. it can be done with regular mechanic's tool. If there is space to use them. make a drawing of the belt pattern before you do anything. it make it much easier to put back on. i made that mistake. Take what ever tool you are going to use and slowy turn the bolt counter clockwise. you should be able to see the tension on the belt release. Slide the belt off of one of the components, and return the tensioner to it original place. notes. the tool needed is not expensive, and can be found at most parts stores. also replace the belt with one that is the same as the one you removed. some have anywhere from 4-7 grooves. hope it helps. duboff
It depends on the engine and if you have A/C. Check out greatlakesxj.com/tech.html for the maintenance manual. Belt routings are on pages 939 and 940. Please be sure to leave a small donation so that they can maintain the website.
Almost every car and truck since 1980 has a belt routing guide on a sticker under the hood. This is most often placed on the radiator shroud or radiator mount but can be found other places like on the bottom side of the hood. If the sticker is gone then go to your local automotive parts dealer like NAPA and ask them to please look it up for you. A nice counter guy - or girl- would be happy to check their books for you and hand you a print out. Be sure to have the make, model and engine info with you. Mitch
best bet is to buy the haynes or chilton manual. may be ona sticker the hood with other belt diagrams. if ur gonna change the belt i highly recomend the manual. not essentially hard but you need to follow book pretty closely. im sure if you look hard enough you find diagrams somewhere on line. hey 4 25 bucks will save you hrs of trying to find what you need.good luck
There is a tension pulley to the left of the alternator. Put a 19mm socket with a torque wrench on the pulley nut. Turn the nut in a counter-clockwise direction. This will lift the pulley away from the belt and allow you to slip it off. Install is the reverse of removal.
it really depends, are you talking about naruto or a real ninja?
Ranks of a real ninja:well real ninjas start at the rank of sapphire star, next the emerald star,the ruby star, the sapphire moon, the emerald moon, the ruby moon and then the shadow eye the shadow eye is for masters, u can tell if your fightin a ninja and what rank they are because they will show the little tatoo of their rank before you fight them, if they're anything more then a emerald star i wouldn't fight them, they live for killing. Ranks in Naruto:First, you go as an Academy Student. After becoming a real ninja, the student becomes a Genin. Genins are assigned in teams made of 3 students and a Sensei. Next, The Genin becomes a Chunin, then a Special Jonin, next is ANBU Black-Ops and finally, a Jonin.PS. ANBU are the ones wearing Those masks but they're different from the Ninja Trackers.
In alot of cases the cost of labor in replacing the belt is more than the belt costs. I would need to know your vehicle year, make, model, and engine size to give you better information.
