Belt Tension Inspection

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.

Removal & Installation

Belt replacement is a relatively simple matter rotating the tensioner off the belt (to relieve tension) and holding the tensioner in this position as the belt is slipped from its pulley. The tensioner arm contains a machined receiver for a 3 / 8 in. driver from a ratchet or breaker bar.

1. Before you begin, visually confirm the belt routing to the engine compartment label (if present) or to the appropriate diagram in this section (if the label is not present). If you cannot make a match (perhaps it is not the original motor for this van), scribble your own diagram before proceeding.
2. Disconnect the negative battery cable for safety.
3. Install the appropriate sized breaker bar, wrench, or socket to the tensioner arm or pulley, as applicable.
4. Rotate the tensioner to the left (counterclockwise) and slip the belt from the tensioner pulley.
5. Once the belt is free from the tensioner, CAREFULLY rotate the tensioner back into position. DO NOT allow the tensioner to suddenly snap into place or damage could occur to the assembly.
6. Slip the belt from the remaining pulleys (this can get difficult is there is little room between the radiator/fan assembly and the accessory pulleys. Work slowly and be patient.
7. Once the belt is free, remove it from the engine compartment.

To install:

1. Route the belt over all the pulleys except the water pump and/or the tensioner. Refer to the routing illustration that you identified as a match before beginning.

2. Rotate the tensioner pulley to the left (counterclockwise) and hold it while you finish slipping the belt into position. Slowly allow the tensioner into contact with the belt.
3. Check to see if the correct V-groove tracking is around each pulley.
   WARNING Improper V-groove tracking will cause the belt to fail in a short period of time.
   
4. Connect the negative battery cable.

Pop the hood of the car and locate the serpentine belt routing diagram. The diagram on the 2003 Chevrolet Impala is on top of the fan shroud. The diagram will be a picture of all of the accessory pulleys and how the serpentine belt is routed among the pulleys. This diagram will give you the exact direction for routing the new belt onto the pulleys. If you cannot find a serpentine belt routing diagram, take a notepad and pen and draw out the exact routing diagram of the old belt across the pulleys.

2 Locate the serpentine belt tensioner. It is located below the alternator on the left front side of the engine. The tensioner on the 3.4 liter, 3.5 liter and the 3.9 liter engines will require a 3/8 ratchet to release the belt tensioner. The 3.8 liter engine will require a ratchet and a 15 mm socket for the belt tensioner. Rotate the belt tensioner clockwise to loosen and remove the belt from the belt tensioner pulley.

3 Slide the old belt from the belt tensioner pulley. Remove the belt from the remaining pulleys and pull the belt from the engine compartment.

4 Route the new belt across the crankshaft pulley first. The crankshaft pulley is the big pulley on the bottom of the engine in the center. Then route the serpentine belt across the remaining pulleys as directed by the serpentine belt routing diagram. Leave the belt tensioner pulley for last.

5 Rotate the belt tensioner clockwise again to relieve the tension and slide the new belt across the top of the belt tensioner pulley. Release the belt tensioner and the belt will tighten up as the tensioner applies pressure to the belt. Make sure the new belt is properly seated in all the pulleys.

6 Crank the engine and inspect the belt again to make sure that it stays seated in the pulleys.

Move the Grand Marquis's serpentine belt tensioner off the serpentine belt with the serpentine belt tool. Pull the belt of the remaining pulleys by hand. Take the belt out of the engine well. Wrap the new belt around the bottom portion of the crankshaft pulley. Follow the belt routing diagram to route the belt over each remaining pulley until only the tensioner remains. Move the Grand Marquis's serpentine belt tensioner aside once more and slip the belt onto the tensioner pulley.Hold the belt in place with one hand while you move the tensioner slowly back into position with the other.

if you have never installed a serpentine belt, it sometimes can be a chore, 1st you need to look under neath you cars hood for a serpentine belt diagram, it will show how the belt is routed, next you will need the approriate size socket, and ratchet to put onto the belt tensioner and route the belt back on to the routeing as reqiured, and once you get to the tensioner with the tool , pull back onto the tensioner and slip the belt back on , make sure that the belt is routed correctly, and evenly through the routeing. sometimes , it might take 2 people to do this, the type of socket on most are 14 or 15 metric size sockets, or you might have to slip a socket onto the bolt of the tensioner to see which one will fit, hope that this information has helped you. also you have to ask yourself a question, why did the belt come off, it is worn, or is the belt tensioner wearing out, and not holding the tension properly to the belt.

These instructions will help you . and also the picture below will help you more.
1
Locate the belt-routing diagram, printed on the fan shroud or possibly applied to the underside of the hood. This diagram shows you how to properly route the new belt, as well as identifying the location of the various pulleys, including the serpentine belt tensioner.
2
Move the belt tensioner off the Sable's belt using the serpentine belt tool. The tool connects to the side of the tensioner's arm and essentially acts as a handle for use in moving the tensioner. You can purchase a serpentine belt tool at most auto-part retailers.
3
Slip the belt away from the tensioner with your free hand and release the pressure on the tensioner with the tool. Pull the belt off the rest of the pulleys by hand and then remove it from the engine well.
4
Grab the old belt and new belt with one hand and put your foot through the other end of the belts. Stretch them both to their full length and check to ensure their both the same size. The old belt may have up to one-inch of extra length due to normal stretching that occurs during the belt's service life.
5
Wind the new belt, rib side to the pulley, around the crankshaft pulley. Consult the routing diagram and route the belt to the next pulley on the diagram. Continue to route and then check the diagram until you have the belt wound around every pulley except the belt tensioner pulley.
6
Double check to make sure the belt routes exactly as shown on the diagram and then move the tensioner aside once more so you can route the belt over the tensioner pulley as shown in the diagram. Move the tensioner back into place slowly and remove the tool.

Good luck

The diagram can be found here.
Remove the upper fan shroud and aircleaner assemblies for easy access.
To release tension on the belt turn the tensioner pulley nut clockwise and slip the belt off the alternator pulley. To refit the belt route as shown over every pulley except the alternator, once again release the tensioner and fit the belt to the alternator. See that the belt is properly seated over every pulley before restarting the engine.

2UZ-FE Engine
To remove the serpentine belt on the 2UZ-FE engine, position a suitable sized wrench or ratchet and socket over the belt tensioner bolt, rotate the tensioner counterclockwise to release the belt tension, then remove the belt. The pulley bolt for the tensioner has a left-hand thread.
When installing the belt, make sure it fits properly in the ribbed grooves and check to be sure the belt has NOT slipped out of the groove on the bottom of the pulley.

2.0L Engines
See Figures 11, 12 and 13
The accessory drive belt for 2.0L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner.
Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension.
The belt tensioner has a belt length indicator. If the indicator marks are not between the MIN and MAX marks, the belt must be replaced.
