What is the function of the drive belt and how is it installed and removed on Buick LeSabre?

A tension spring provides belt tension to all accessories integrating to the engine structure while the drive belt supports their operation. Decaying belts produce squeaking noises during start and stop but this does not affect their longevity. The tensioner allows control of belt tension throughout its designated range however extending use beyond this area might result in tension issues and equipment harm. The first step to remove the drive belt includes rotating the tensioner to attain access for belt removal. To install the drive belt it is necessary to once again rotate the tensioner.

What are the functions of the drive belts in the supercharged 3800 engine and how are they maintained and replaced on Buick Regal?

The supercharged 3800 engine operates with two belts where the outer belt controls the supercharger operation simultaneously the inner belt manages the generator and three additional devices which include the Power Steering Pump and coolant pump and air conditioning compressor that mount to the engine rigidly. A spring-loaded system called a tensioner controls the Drive Belt tension and each belt operates with its unique tensioner unit. Drive Belt squeaks during engine start and stop are standard and have no impact on its lifespan yet using a tensioner beyond its operational boundaries might result in poor tension management and possibly lead to tensioner damage forcing users to replace the belt. First remove the drive belts through this procedure: apply a 15-mm box end wrench to the pulley nut before tilting or rotating the Drive Belt tensioner and unfasten the supercharger Drive Belt and then the inner Drive Belt. Apply the 15-mm box end wrench to lift or rotate the Drive Belt tensioner before installing first the inner Drive Belt then repeating with the supercharger Drive Belt tensioner to install the supercharger Drive Belt.
