Drive Belt: Description and Operation
SERPENTINE BELTA single (serpentine) belt may be used to drive all engine mounted components. All driven components are rigidly mounted to the engine. Drive belt tension is maintained by a spring loaded belt 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.
