Chevy Truck 1996-98 4.3L, 5.0L and 5.7L
Here is the serpentine belt diagram for a 1996-1998 Chevy truck with the 4.3, 5.0 and 5.7 liter engine. Removing the belt is very simple. Using breaker bar and a socket that fits the center bolt of the tensioner pulley, rotate the tensioner to create slack on the belt and slip it off the tensioner pulley. Inspect all of the pulleys and make sure they are free of any dirt, debris or fluids.
To replace the belt, route the belt according to the diagram posted above leaving the tensioner pulley for last. Rotate the tensioner pulley again with your breaker bar and socket and slip the belt of the tensioner. Inspect all pulleys and make sure the belt is aligned correctly on each.
