What is the role of drive belts in the overall operation of a Mercury Grand Marquis and its components?

Key vehicle system operations depend on drive belts that are situated in front of the engine. Regular inspections and maintenance keep them from breaking. Accessories determine how many belts are used. Inspect both faces of each belt for cracks, splits, broken edges, and glazed surfaces. The belt is checked to see if it is properly adjusted by visual means or by pressing it. Modify the tensioner or alternator to adjust tension. Replace the old belt by raising the tensioner arm, taking off the old one, and installing a new one. Take off the belt first, then remove mounting bolt before putting in place the new tensioner.
