Accessory Drive Belt: Description

The supercharged 3800 engine uses two accessory drive belts. The outer belt drive the generator and power steering pump. The inner belt drive the supercharger, coolant pump and air conditioning compressor. All driven accessories are rigidly mounted to the engine. Drive belt tension is maintained by a spring loaded belt tensioner. Each belt has its own tensioner.

A belt squeak when the engine is started or stopped is normal and has no effect on belt durability.

The drive belt tensioner can control belt tension over a broad range of belt lengths; however, there are limits to the tensioner's ability to compensate. Using the tensioner outside of its operating range can result in poor tension control and/or damage to the tensioner. The belt should be replaced when this condition occurs.
