Belt Adjustments

CAUTION! To prevent possible injury caused
by someone inadvertently starting the en-
gine, remove the ignition keys from each
starting location (especially if the engine
room/engine compartment cannot be seen
from various remote starting positions such
as a flybridge or enclosed cabin).

Serpentine Belt Engines

Some 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 three separate belts (alterna-
tor, circulation pump, and power steering belts). The
serpentine belt tension is adjusted automatically and
requires no tension adjustments. However, at least
once per year, have your Volvo Penta dealer check
the serpentine belt for wear. An ideal time to have this
check performed 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 & D coincide
(8.1L engines) and mark B is centered between tick
marks A (all other engines), it's time to replace the
serpentine belt.
