2Maintenance and service
Drive belts
The alternator, power steering pump, and air condi-
tioner compressor depend on drive belts. Satisfactory
performance requires that belt tension be correct. „
2.5 liter models
1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulley in (mm)
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. „ 3.0 liter models
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.
