Serpentine Belt Engines

All engine models use a serpentine belt, which is a
continuous-loop belt threaded through the alternator
pulley, circulating pump pulley, idler pulley, and power
steering pump pulley.
This single belt replaces two separate belts (alternator
and power steering pump belts). The serpentine belt
tension is adjusted automatically and requires no ten-
sion adjustments. However, at least once per year,
have your Volvo Penta dealer check the serpentine
belt for wear or inspect the belt yourself for cracks,
check marks, dry rot, exposed cords, oil or grease. An
ideal time to perform this check is when you have the
gimbal bearing lubricated.
Alternatively, you may check the indicators, located on
the automatic tensioner housing, to determine the
amount of wear. When tick marks C and D coincide,
it's time to replace the serpentine belt.
