Subaru 4 cylinder does not use a serpentine belt. The 6 cylinder instructions are rather simple, same as my '88 Cavalier and I presume any car that uses a serpentine belt. This comes from the factory service manual:
remove collector cover
install tool to tensioner pulley installation bolt
rotate tool clockwise to loosen the belt and remove
install in reverse order
