I have a chevy cavalier and i need a diagram for the serpentine belt it is half of the pulleys and i need to put it back on

Go to http://serpentinebeltdiagrams.com/2003-cavalier-2-2l/
They should be the same as shown in one of the two diagrams.

You use a breaker bar to move the tensioner, remove the belt and use the tensioner to put it back. You draw the belt and pulleys on a sheet of paper before removing, otherwise there should be a small diagram of the belt and pulley positions on the fan shroud or radiator support.

1. 1 Check to ensure the Sienna's engine is cold, then make sure the Sienna is in park, the ignition is in the off position and the key is removed from the ignition to prevent any possibility of the engine engaging during the serpentine belt replacement.
   
2. 2 Open the hood and locate the serpentine belt routing diagram sticker on the side of the engine casing. Study it for a moment before removing the existing belt. It is essential the new belt be installed exactly as the diagram indicates.
   
3. 3 Find the tensioner pulley, the main pulley that controls the serpentine belt, and fit a 1/2-inch socket wrench over the self-tensioner on the outside of the pulley.
   
4. 4 Pull the wrench to the left to move the pulley forward, which loosens the belt, then remove the belt.
   
5. 5 Compare the old serpentine belt with the new, replacement belt for length, width and number of grooves on the belt's underside. Be certain the replacement belt is the right part.
   
6. 6 Fit the new belt on to each pulley according to the serpentine belt routing diagram on the manufacturer's sticker, or according to the drawing made prior to removing the old belt. Fit the new belt on to the tensioner pulley last, again applying pressure on the pulley's self-tensioner with the half-inch socket wrench to loosen the pulley.
   
7. 7 Release the pressure on the self tensioner and allow the tensioner pulley to ease back into place, thereby tightening the new serpentine belt with the appropriate tension.
   
8. 8 Remove the wrench and close the hood.
   

Thank you and good luck,

The waterpump pulley is smooth. It the smooth side of the belt touching the pulley or the grooved side. It should be the smooth side.

Diagram should be under the hood
The auto tensioneris down low and dificult to get to.
If it has not been changed in a while you will need a long thin push stick and a serpentine tool.
Push on the belt hard at the auto adjuster and pop the belt off the smooth pully (located top).
hook up the serpentine belt tool and then mount the new belt

diagram should be on the radiator shroud / top of radiator

Helllo there:
Simply click on the links that i have provided and the routing diagram will be there ok

there is a pullry near the center with a half inch drive rachet wrench will fit in push down to relieve presure

that is your tensioner pully and it very well may be going bad new one isnt very expensive and can be easily removed with a socket wrench and replaced please be sure to make a diagram of the serpentine belt before you remove so that you will rember how it goes back on

there will be a diagram of the routing of the belt on the bottom side of the hood. You need to specify what engine you have also. One common thing is the tension pulley, you will need to pry on it to relieve tension in order to put the belt on. Make sure you save the alternator for last as you can get to it a lot easier that the rest.
