5. Slowly pour the coolant and fill up to just below the
filler neck, allowing enough room to add genuine Sub-
aru cooling system conditioner in the radiator. Add
genuine Subaru cooling system conditioner until the
coolant level reaches the filler neck. Do not pour the
coolant too quickly, as this may lead to insufficient air
bleeding and trapped air in the system.

ed parts. The alcohol contained in the engine
coolant may damage the paint surface.

Maintenance and service
Air cleaner element
Do not operate the engine with the air cleaner
element removed. The air cleaner element not
only filters intake air but also stops flames if the
engine backfires. If the air cleaner element is
not installed when the engine backfires, you
could be burned.
The air cleaner element functions as a filter screen.
When the element is perforated or removed, engine
wear will be excessive and engine life shortened.
The air cleaner element is a dry type. It is unnecessary
to clean or wash the element. ! Replacing the air cleaner element
Replace the air cleaner element according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet”. Under extremely dusty conditions, re-
place it more frequently. It is recommended that you
always use genuine SUBARU parts. !

bles. " Make sure the cables are replaced in the cor-
rect order.

ommended that you have the spark plugs replaced by
your SUBARU dealer. The spark plugs should be replaced according to the

Maintenance 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
A) Power steering pump pulley
B) Air conditioner compressor pulley
C) 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 SUB-
ARU dealer.
