1996 Blazer: How do install a 1996 chevy blazer serpentine belt...

You use a breaker bar to move the tensioner, remove the belt and use the tensioner to put it back. You draw the belt and pulleys on a sheet of paper before removing, otherwise there should be a small diagram of the belt and pulley positions on the fan shroud or radiator support.

IF FOR SOME REASON THE BELT ROUTING STICKER IS NO LONGER ON THE CORE SUPPORT OR ON THE BACK OF THE HOOD A ROUTING DIAGRAM CAN BE OBTAINED AT YOUR LOCAL AUTO ZONE THEY WILL GIVE YOU A PRINT OUT FOR FREE

Please take a Google search for the place you are residing to get to the nearest spare parts store for your spares.

Have you checked the pulley alignment? do any of the pulleys have excessive play in the bearings they ride on? these are the reasons for the belt coming off, there is no other.

Look around the radiator mount or on the hood for the diagram
but just in case http://images.wrenchead.com/smartpages/partinfo_resize/GAT/S7004.jpg

There is a belt tensioning pulley. It's spring loaded and if you put a wrench on the center nut you should be able to remove the tension on the belt...

The water pump is in front of the engine block. If you follow the serpentine belt to the pulley that connects to the radiator fan. That pulley also is the water pump pulley,and you should see a large radiator hose at the bottom,passenger side. There should be a smaller hose from the top. Hope this help, keep me posted. Be glad to help.

Doesn't it have a diagram on the radiator top cover, just under the hood?
