The Serpentine belt broke on my 2006 Saturn Ion and am trying to replace but cant find the belt diagram?

my first thought would be the squealing serpentine belt or could be brake pads. Combining squeal and stall from stopped position maybe you have a bearing going out on something the serpentine belt runs on. example if belt tensioner or A/C clutch bearing going bad could cause drag on serpentine belt. If a bearing is going bad you may be able to hear it under the hood.

Did you loosen the bolt in the center of the tensioner pulley?

On this website you find fuse box diagram diagram and description for Saturn ION (2007)

OK, so find out why? belts usually dont just break without warning. check the tensioner and pulleys.

you need to buy a new one . remove the screws. remove the broken one and reinstall the new one....seriously

Click on the following direct Link. It has the Serpentine Belt Diagram for the L-Series for your specific engine and options (AC/No AC etc.). It has other additonal diagrams for your future use. It also has diagrams on how to rotate/move the Tensioner Pulley/Arm to loosen and remove the Belt.

Standard Rules to Removal the Serpentine Belt:
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 OR 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:
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.

for the most part there is a tensioer holding the belt on give these websites a try www.alldatadiy.com and www.autozone.com wish you the best of luck Michigan Man.

Autozone or a similar parts retailer will print one for you for free.

The fuse box in the 06 ion is under the floor covering on the drivers side seat. Just move the seat all the way to the rear and then starting in the front near the pedals pull up the floor covering which is attached by velcro.
