2005 Buick LeSabre Drive Belt Parts and Q&A

• Q: How does the drive belt function in relation to engine-mounted accessories and How to replace it on 2005 Buick LeSabre?

  A: The drive belt operates all engine-mounted accessories which stay rigidly mounted onto the engine by functioning through the tension provided by a spring-loaded belt tensioner system. A belt squeak emits during engine starting or stopping is typical behavior and does not weaken the belt because the tensioner regulates tension across multiple belt lengths. The first step to replace L36 involves rotating the tensioner in a counterclockwise direction until you pull the drive belt from the engine. Installation of the accessory drive belt requires the user to first position it properly onto the pulleys and then use the tensioner to rotate counterclockwise to install the drive belt .
