11-14Maintenance and service
Cooling system
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap isremoved.
CAUTION
. The cooling system has been
filled at the factory with a high
quality, corrosion-inhibiting,
year-around coolant which pro-
vides protection against freezing
down to 33 8F( 36 8C). For add-
ing, use genuine SUBARU cool-
ant or an equivalent: a mixture of
50% soft water (or clear and
drinkable water) and 50% phos-
phate or non-amine type coolant.
Use of improper coolants may
result in corrosion in the cooling
system. It is important to main-
tain protection against freezing
and corrosion, even if freezing temperatures are not expected.
Never mix different kinds of cool-ant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Hose and connections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Check the fuse and replace it
if necessary. If the fuse is not blown, have
the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness. &
Engine coolant
! Checking the coolant level
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the “LOW ”level mark, add coolant up to the
“ FULL ”level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.

3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.
CAUTION
. Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off. .
Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
! Changing the coolant
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant isreplaced.
Change the engine coolant and add
genuine Subaru cooling system condi-
tioner using the following procedures
according to the maintenance schedule
in the “Warranty and Maintenance Book-
let ”. 1. Remove the under cover.

2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap is removed.
4. Install the under cover.
Non-turbo models
1) Fill up to here
Turbo models
1) Fill up to here
5. Slowly pour the coolant and fill up to
just below the filler neck, allowing enough room to add genuine Subaru cooling
system conditioner in the radiator. Add
genuine Subaru cooling system condi-
tioner 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.
Coolant capacity (Guideline): 2.5-liter non-turbo models:MT. 6.8 US qt (6.4 liters, 5.6 Imp qt)
AT. 6.7 US qt (6.3 liters, 5.5 Imp qt)
2.5-liter turbo models: MT. 7.7 US qt (7.3 liters, 6.4 Imp qt)
AT. 7.6 US qt (7.2 liters, 6.3 Imp qt)
3.0-liter models: 7.6 US qt (7.2 liters, 6.3 Imp qt)
CAUTION
. Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant

may damage the paint surface.
6. Pour the coolant and fill to the reser-
voir tank’s “FULL ”level mark.
7. Put the radiator cap back on and
tighten firmly. At this time, make sure that the rubber gasket in the radiator cap is
correctly in place.
8. Start and run the engine for more than
five minutes at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the
coolant cools down (122 to 140
8F [50 to
60 8C]). If there is any loss of coolant, add
coolant to the radiator ’s filler neck and to
the reserve tank ’s “FULL ”level.
10. Put the radiator cap and reservoir cap
back on and tighten firmly. Air cleaner element
WARNING
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.
CAUTION
When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perfo-
rated 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 ele-ment. Maintenance and service

WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to anaccident. Aluminum wheels
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety. .
When any of the wheels is removed
and replaced for tire rotation or to change
a flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose,
tighten it to the specified torque. . Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the wheel. . Never let the wheel rub against sharp
protrusions or curbs.. Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel. . When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for aluminum wheels. Windshield washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paintdamage.
If you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank. Maintenance and service
