How to replace the drive belt and maintaining tension with the tensioner on 2004 Buick LeSabre?

The drive belt activates all engine-mounted accessories through a tension system that uses a spring-loaded belt tensioner for support. Engine start and stop noises from the belt are typical and do not affect the belt longevity given that the tensioner maintains adequate tension across different belt lengths. Before belt replacement you should turn the tensioner mechanism counterclockwise to eliminate the drive belt from the engine. Installing the accessory drive belt requires firstly placing it onto the pulleys then utilizing the tensioner to rotate in a counterclockwise direction for drive belt installation.
