How do you put a belt on a 95 Oldsmobile regency?

To put a belt on a 1995 Oldsmobile Regency, first ensure the engine is off and cool. Locate the serpentine belt routing diagram, usually found on a sticker near the engine or in the owner's manual, to understand how the belt should be threaded around the pulleys. Release tension on the tensioner pulley using a wrench or ratchet, then slide the new belt into place, following the correct routing. Finally, release the tensioner to secure the belt and double-check the alignment before starting the engine.
