GMC Workshop Manuals

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.

Click this link to a Dayco belt PDF file. Look through the catalog pages for your Model car and engine size - illustration number, then find your belt diagram at the bottom of the catalog.

Many auto manufacturers place the belt diagram under the hood. I've seen in on the underside of the hood, on the strut housing, and along the front of the engine. The diagram may be in your owner's manual as well.

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

Above the photo are 2 PDF documents. The first - Routing Guide gives you the diagram code for the car and engine. See page 30 for the 89 CHEV Corsica 2 liter.
There are 2 belts - one for the air conditioned equipped engine (diagram 6-3) and one without the aircon (diagram 5.3).

Next go to the second document - Illustration guide PDF document - for those 2 belt diagrams.
