To check belt tension, place a straightedge (ruler)
across two adjacent pulleys and apply a force of 22 lbs
(98 N, 10 kg) midway between the pulleys by using a
spring scale. Belt deflection should be the amount
specified.

It is unnecessary to check belt tension periodically be-
cause your engine is equipped with an automatic belt
tension adjuster. However, replacement of the belt
should be done according to the maintenance sched-
ule in the "Warranty and Maintenance Booklet". Con-
sult your SUBARU dealer for replacement.
If a belt is loose, cracked, or worn, contact your
SUBARU dealer.
