Changing the coolant
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant is
replaced.
Change the engine coolant and add gen-
uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”.
1. Remove the under cover.
2.5-liter models
1) Drain plug 3.0-liter models
1) Drain plug
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.
4. Install the under cover.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.

Drive belts
The alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires 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 tensi on, place a straight-
edge (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 pe-
riodically because your engine is
equipped with an autom atic belt tension
adjuster. However, replacement of the
belt should be done according to the
maintenance schedule in the “Warranty
and Maintenance Booklet”. Consult your
SUBARU dealer for replacement.
If a belt is loose, cr acked, or worn, contact
your SUBARU dealer.Manual transmission oil „ Checking the oil level

1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again. 1) Upper level
2) Lower level
3. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil through the dipstick hole to
bring the level up to the upper level.
„ Recommended grade and
viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together.
Oil grade:

Be careful not to spill manual trans-
mission oil when adding it. If oil
touches the exhaus t pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off.

„Recommended fluid
Use one of the following types of automat-
ic transmission fluid.
Genuine Subaru Automatic Transmis-
sion Fluid Type-HP
IDEMITSU ATF HP
Castrol Transmax J
Pennzoil ATF-J*
* Available only in the USA (except
Alaska and Hawaii)
NOTE
Using any non-specified type of auto-
matic transmission fluid could result in

Power steering fluid „Checking the fluid level
The power steering fluid expands greatly
as its temperature rises; the fluid level dif-
fers according to fluid temperature. There-
fore, the reservoir tank has two different
checking ranges for hot and cold fluids.
Check the power steering fluid level
monthly.
1. Park the vehicle on a level surface, and
stop the engine.
2. Check the fluid level of the reservoir
tank.
When the fluid is hot after the vehicle has
been run: Check that the oil level is be-
tween “HOT MIN” and “HOT MAX” on the
surface of the reservoir tank.
When the fluid is cool before the vehicle is
run: Check that the oil level is between
“COLD MIN” and “COLD MAX” on the sur-
face of the reservoir tank.
3. If the fluid level is lower than the appli-
cable “MIN” line, add the recommended
fluid as necessary to bring the level be-
tween the “MIN” and “MAX” line. If the fluid level is extreme low, it may indi-
cate possible leakage. Consult your
SUBARU dealer for inspection. „

Be careful not to burn yourself be-
cause the fluid may be hot. yWhen power steering fluid is be-
ing added, use only clean fluid,
and be careful not to allow any dirt
into the tank. And never use dif-ferent brands together.
y Avoid spilling fluid when adding it
in the tank.

y Be careful not to spill power steer-
ing fluid when adding it. If power
steering fluid touches the exhaust
pipe, it may cause a bad smell,
smoke, and/or a fire. If power
steering fluid gets on the exhaust
pipe, be sure to wipe it off.

Aluminum wheels
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety. yWhen 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, tight-
en it to the specified torque.y Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.y Never let the wheel rub against sharp
protrusions or curbs.y Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel. y When wheel nuts, balance weights, or
the center cap is replaced, be sure to re-
place them with genuine SUBARU parts
designed for aluminum wheels.Windshield washer fluid
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.
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could in-
terfere with brake caliper operation
and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of vehi-
cle control could lead to an acci-
dent.
Never use engine coolant as washer
fluid because it could cause paint
damage.
