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

1. Disconnect the negative battery cable.
2. Rotate the auto tensioner clockwise to release tension, then remove the drive belt.

To install:

1. Install drive belt (A). Route the belt over the components in the following order: Crankshaft pulley - A/C pulley - idler pulley - generator pulley - water pump pulley - P/S pump pulley - tensioner pulley.
2. Rotate auto tensioner arm in the counter-clockwise moving auto tensioner pulley bolt with wrench.
3. After putting belt on auto tensioner pulley, release the auto tensioner pulley slowly.

It is probably the tensioner pulley that's gone bad. It can be replaced separately, if you can purchase the pulley separately. As to how to go about changing it in such a small space, it's definitely possible, with the right type of tools. That's why mechanics have so many different shapes and lengths of the same size tools.

On the tension pulley, using a ratchet or breaker bar and a socket, apply pressure to the pulley to loosen the belt. remove the belt and thread the new in place, again applying pressure to the tension pulley, and finish replacing the belt. here's the pattern. t/p is you tension pulley. hope this helps

The problem is the rear motor mount is filled with hydraulic fluid that leaks onto the accessory drive belt. The motor mounts fail prematurely and the fluid makes the belt squeak. Toyota dealership I took my 2006 Corolla to replaced the motor mount and belt free of charge.

there should be a picture of how the belt goes on on the top of the radiator housing. Also there should be a wheel that the belt travels over that doesn't operate anything. It's called a tensioner pulley. You can pry the tensioner pulley down to get the belt on and off. Hope this helps!

The Belt Diagram should be on the underside of your hood, however they have a way of disappearing.

Standard Rules to Removal the Serpentine Belt with an Automatic 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 the Tensioner Pulley/Arm - 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.
4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

Standard Rules for Installing the Serpentine Belt with an Automatic Tensioner:
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.

You'll have to remove the engine cover under the bottom so you can position the new belt on the pulleys properly. Get a wrench or tensioner tool and turn the tensioner clockwise to relax the drive belt. Don't apply excessive force.

It's hard to draw a picture with words, but looking at the engine from the passenger side of the car, there are basically two top pulleys, two middle, and two bottom. The drive belt goes around the outside of the two top and two bottom, and on the inside of the two middle.

Crank the tensioner to get some slack in the belt and slide it off the uppermost, most easily accessible pulley. Remove the old belt. Route the new belt in accordance with the belt routing diagram and crank the tensioner the same direction as before to begin getting the belt over the uppermost pulley. Slide a screwdriver under the belt and over the pulley to leverage the new belt on. Release the tensioner and check for belt tautness. If the belt is loose, you've either purchased the wrong size or have misrouted the serpentine belt.

I can get you a diagram on monday but it goes from the alternator to the power steering pump then around the tensioner pulley then around the crank pulley then to the a/c compressor then pull on the tensioner to give you some slack and slip it on the waterpump.I hope that helps.Let me know if you still need the diagram

Hi there weekie,

Simple and easy. Really.

• Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
• The tensioner pulley is on a spring loaded arm. Get your socket on the center nut of this pulley.
• Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt off.
  
• Slowly release the tension.
  
• You're done
