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
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top off the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is shortened to that of the mixingcoolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con- nections
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.

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 race the engine at 2,000 to
3,000 rpm for 5 to 6 times within 40seconds.
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

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.
Washer fluid level gauge
Remove the washer tank filler cap, then
check the fluid level indicated by the level
gauge (attached to the inside of the cap).
If the level is near the “Low ”mark, add
fluid until it reaches the “Hi ”level on the level gauge or the
“Full ”mark on the tank.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.
Washer Fluid
Concentration Freezing
Temperature
30% 10.48F( 12 8C)
50% 48F( 20 8C)
100% 49 8F( 45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside Maintenance and service
