Park your Subaru on a level surface and open the hood.
Disconnect the ground (black) battery cable using a wrench. This will prevent the cooling fan from activating.
Locate the serpentine belt
routing diagram in your engine compartment and compare it to the actual
routing of the installed belt. Make sure the routing on the label
matches the actual routing. If they do not match or there is no label,
note the actual routing on a piece of paper for later reference.
Locate the belt tensioner pulley
on your Subaru model. If the tensioner is equipped with a squared hole,
use a large breaker bar with a 1/2-inch (13 mm) drive. Otherwise, use a
ratchet and socket of the proper size on the tensioner pulley center
Rotate the tensioner pulley away from the belt to release the belt tension.
Pull the belt off of one of the
pulleys and slowly release the tensioner pulley back into position. Do
not let the tensioner pulley snap back or you may damage an internal
Finish removing the serpentine belt from the rest of the pulleys and the engine compartment.
Installing the New Serpentine Belt
Match the old belt to the new
one and make sure they are of the same length and configuration. It is
normal for the new belt to be slightly shorter since the old one has
been stretched through use.
Route the new serpentine belt
through all of the pulleys except the tensioner pulley. Use the diagram
on the engine compartment or your notes, as a reference, to properly
route the belt.
Insert the large breaker bar into the square hole or the ratchet and socket into the tensioner pulley center bolt.
Rotate the tensioner pulley in the same direction you did to release the belt tension.
Slide the serpentine belt onto the tensioner pulley.
Release the tensioner pulley back into position.
Look at all the pulleys and make
sure the serpentine belt is properly seated on each one. Otherwise,
release the belt tension and adjust the belt.
Connect the ground (black) battery cable using the wrench.
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.
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.
Slide the old belt from the belt
tensioner pulley. Remove the belt from the remaining pulleys and pull
the belt from the engine compartment.
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.
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.
Crank the engine and inspect the belt again to make sure that it stays seated in the pulleys.
Park the Pontiac in a safe work area and open the hood.
Inspect the top of the black plastic cover that surrounds the fan for the serpentine belt routing diagram. This diagram has the instructions for installing the new serpentine belt around the accessory pulleys.
Inspect the front of the engine and locate the automatic belt tensioner. The tensioner on the 1999 Pontiac model vehicles is located between the alternator and the crankshaft pulley. The tensioner has a pulley on one end with a bolt head in the center of the pulley. Use the bolt head to rotate the tensioner.
Turn the tensioner counterclockwise with the breaker bar and a metric socket. Pull the belt out from under the tensioner pulley with your other hand. Then, slowly let the tensioner retract until it stops.
Pull the belt out of the other remaining pulleys. Then, pull the belt out of the enginebay and lay it on the ground.
Route the new belt around the crankshaft pulley. Then, route the new belt around the other remaining pullleys by using the serpentine belt routing diagram for instructions.
Rotate the tensioner pulley counterclockwise with the breaker bar and socket. Then, slide the new belt under the tensioner pulley. Slowly let the tensioner retract until it stops. The tensioner pulls all of the slack out of the belt and brings the new belt to the proper tension. Remove the breaker bar and socket from the tensioner pulley.
Inspect the new belt to ensure that it is seated inside of all the accessory pulleys as directed by the diagram. Then, crank the engine and allow it to run for about 15 seconds. Turn the engine off. Inspect the belt again once more to ensure that
the belt is still around each pulley. Close the hood.
buy a new serpentine belt and refer to the diagram on the box. it will show you how to route the belt. also, there is a belt tensioner. it can be pulled back with a large prybar so you can slip the belt on the pulley.
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.
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.
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.
Pull the wrench to the left to move the pulley forward, which loosens the belt, then remove the belt.
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.
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
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.
Here's the procedure on how to release and replace the tension belt of your car.
Open the hood on the Volvo S-60 and find the serpentine-belt routing diagram. The diagram should be attached to the top of the fan shroud that covers the radiator. If not, draw out the exact routing method of the serpentine belt around each pulley with a pen and a piece of paper.
Locate the serpentine-belt tensioner that is in the very center of the engine. The tensioner will have a square bolt head in the center of the tensioner pulley.
Slide the open end of the 5/8-wrench onto the square bolt head in the center of the belt-tensioner pulley. Turn the tensioner pulley counterclockwise and slide the serpentine belt off of the tensioner pulley.
Remove the serpentine belt from the other pulleys and pull the belt out of the engine compartment.
Slide the new serpentine belt into the engine compartment and around the crankshaft pulley.
Route the new serpentine belt around each pulley. Turn the belt-tensioner pulley counterclockwise again and slide the serpentine belt around the tensioner pulley. Release the tensioner and it will tighten the belt around the pulleys. Look over the belt to ensure that it is inside of each pulley.
Crank the S-60 and look over the serpentine belt with the motor running. Let the engine run for about one minute and shut the engine off. Close the hood.
Hello,Locate the serpentine belt tensioner on the front of the engine.The tensioner is what keeps tension on the belt and keeps the belt from coming off.The tensioner will have a bolt head in the middle of it that a 15mm socket will fit STEP 2:Look on the hood base where the hood lock attaches to the base and see if there is a belt diagram.This diagram will give you the exact instruction for properly routing the belt across the pulleys.If there is no diagram there,you will need to write down the exact routing of the belt on the pulleys on a notepad STEP 3:Put the 15mm socket onto the ratchet and put the ratchet onto the bolt head on the belt tensioner. STEP 4:Turn the tensioner clockwise to relieve the tension on the belt and remove the belt from all of the pulleys STEPS 5:Remove the new serpentine belt the same way that the old one came off by following the belt routing diagram instruction.Do not put the belt across the tensioner until last.Keep in mind that the belt will only go on one way and be right. STEP 6:Put the ratchet with the 15mm socket back on the belt tensioner and rotate the tensioner clockwise to give you enough room to slide the new belt across the belt tensioner pulley.Slide the belt onto the belt tensioner pulley and release the belt tensioner.Look over the belt and double check to make sure that the belt is running across all of the pulleys correctly STEP 7:Crank the car and inspect that the belt is secure and is staying in the grooves on all of the pulleys.
My sincere apologies for the severly delayed response. I am personally going back to answer your unanswered questions.
I do not know if you still need this information, however I am answering it in case you still do.
Click on the following direct Link. It has several Diagrams for your Belt depending on your engine size and options (AC/No AC etc.) AND whether you have Tensioners OR Locking/Adjusting Bolts/Nuts. IF APPLICABLE: These point out the direction of rotation for the Tensioner in order to loosen and reinstall the Belt. IF APPLICABLE: These also point out where the Locking and Adjusting Bolts/Nuts are, to loosen the belt and remove; and reinstall the Belt and .
Standard Rules to Removal the Serpentine Belt with a Tensioner: 1. Find the Tensioner(s). (See Diagrams on Link) 2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating it\moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move. 3. Remove the loosened belt off one of the other more easily accessed Pulleys. Standard Rules for Installing the Serpentine Belt with Tensioners: a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on. b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right. c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley. d. Using your other hand - Pull the Belt up and over the Last remaining Pulley. e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them Let me know if this helped, or if you have additional information or questions.
