Serpentine Belt

CAUTION!
The serpentine belt and pulley system have pinch
points that can cause injury. If the engine is running,
keep fingers away from the belt and all pulleys. Also
be aware of loose clothing and keep away from the
belt and all pulleys.
All engines use a serpentine belt, which is a continu-
ous-loop belt threaded through automatic belt ten-
sioner
A
, alternator pulley
B
, idler pulley
C
, power
steering pump and raw water pump pulley
D
, crank-
shaft pulley
E
, and circulating pump pulley
F
.
Check the indicators, located on the automatic ten-
sioner housing, to determine the amount of tension
loss. When tick marks
G
and
H
coincide, it’s time to
replace the serpentine belt. As long as mark
G
is
between marks
H
and
I
, the belt has adequate tension
on it.
Also check the serpentine belt for:
● Regularly spaced cracks
● Regularly spaced missing chunks
● Dry rot
● Exposed cords or excessive fraying
● Oil or grease
If the belt needs to be replaced, refer to the
Workshop
Manual
for the procedure or take your boat to a Volvo
Penta dealer.
Engine Alignment
Because of the special tools required, a Volvo Penta
dealer must do the engine alignment. This should be
done during off-season storage preparations.
NOTICE!
Failure to periodically check engine align-
ment may result in premature failure of the engine cou-
pler.
