I have been looking recently for a site which gives Serpentine belt routing
diagrams and finally hit the Jackpot.
Gates rubber: Google for this and click on catalogs and go to Micro V belt
Installation for good basic info, and then go to belt and cooling system
products for passenger cars or trucks, look up your model and year, you
will see a reference diagram number in the right hand column.
Then go to the Micro V belt routing diagrams and find the corresponding
routing number and you have a picture of the Serpentine belt routing.
Hope this is useful to others.
