What are the functions of the drive belts in the supercharged 3800 engine and how are they maintained and replaced on 2000 Buick Regal?

The supercharged 3800 engine has two drive belts: the outer one drives the supercharger while the inner one drives the generator, power steering pump, coolant pump and air conditioning compressor. Spring-loaded tensing devices keep the belt under tension. Squeak when engine starts or stops, this is normal and improper tension can lead to damage that requires belt replacement.
