CAUTION
The front side belt, which runs in
conjunction with the following com-
ponents, must be used within the
specified deflection.
. Power steering oil pump pulley
. Alternator pulley
. Crank pulley
Check the deflection of the front side
belt and if there is any looseness,
cracks, wear or unusual noise on the
front side belt, contact your
SUBARU dealer.
Continuing to use the vehicle with
the belt outside of the specification
may cause the engine to malfunc-
tion and the above components to
malfunction.
To check the deflection of the front side
belt, place a straightedge (ruler) across
two adjacent pulleys (alternator pulley and
crank pulley) and apply a force of 22 lbf (98
N, 10 kgf) midway between the pulleys by
using a spring scale. The belt deflection
should be the amount specified. If the front
side belt is loose, cracked or worn, contact
your SUBARU dealer.

The rear side belt is a stretch-type belt,
therefore the deflection does not need to
be checked. If there are cracks or wear
confirmed on the belts and a squeaking
noise is heard from them, contact your
SUBARU dealer.

have the oil inspected by your SUBARU
dealer according to the maintenance
schedule in the “Warranty and Mainte-
nance Booklet”. Consult your SUBARU
dealer for details.
