engine oil SUBARU OUTBACK 2003 3.G Owner's Manual

11-1212. Reinstall the cover under the oil filter.
13. Pour engine oil through the filler neck.
Oil capacity (Guideline): 2.5 liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)3.0 liter models: 5.9 US qt (5.6 liters, 4.9 Imp qt)
The oil quantity indicated above is only a guideline. The necessary quantity of oil depends on the quantity of oil that has been drained.
The quantity of drained oil differs slightly depending on the tempera-
ture of the oil and the time the oil is left flowing out. After refilling the
engine with oil, therefore, you must use the dipstick to confirm that the
level is correct.
14. Start the engine and make sure that no oil leaks appear around the filter ’s rubber seal and drain plug.
15. Run the engine until it reaches the normal operating temperature.
Then stop the engine and wait a few minutes to allow the oil drain
back. Check the oil level again and if necessary, add more engine oil. Recommended grade and viscosity CAUTION
Use only engine oil with the recommended grade and viscosity.
Oil grade: ILSAC GF-3, which can be identified with the new API certification mark (Starburst mark)
or API classification SL with the words “ENERGY CON-
SERVING” (if you cannot obtain the oil with SL grade,
you may use SJ grade “ENERGY CONSERVING ” oil).
These recommended oil grades can be identified by looking for either
or both of the following marks displayed on the oil container.

Indicates the oil quality by API desig- nations
2 Indicates the SAE oil viscosity grade
3 Indicates that the oil has fuel savingcapabilities
In choosing an oil, you want the proper quality and viscosity, as well
as one that will add to fuel economy. The following table lists the rec-
ommended viscosities and applicable temperatures.
When adding oil, different brands may be used together as long as
they are the same API classification and SAE viscosity as those rec-
ommended by SUBARU.
Engine oil viscosity (thickness) affects fuel economy. Oils of lower vis-
cosity provide better fuel economy. However, in hot weather, oil of
higher viscosity is required to properly lubricate the engine.

Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in areas with very high tempera-
tures, or used for heavy-duty applications such as towing a trailer, use
of oil with the following grade and viscosities is recommended.
API classification SL (or SJ): SAE viscosity No.: 30, 40, 10W-50,
20W-40, 20W-50
Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33F ( –36 C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehicle employs an electric cooling fan which is thermostatically

Rubber gaskets3. 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. Changing the coolant
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
Change the engine coolant 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 drainplug.

If a belt is loose, cracked, or worn, contact your SUBARU dealer.
Manual transmission oil Checking the oil level
Check the oil level monthly.
1. Park the vehicle on a level surface and stop the engine.

2. Pull out the dipstick, wipe it clean, and insert it again.
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 upto the upper level. Recommended grade and viscosity
Each oil manufacturer has its own base oils and additives. Never use
different brands together.
Oil grade: API classification GL-5

Power steering fluid
Checking the fluid level
WARNING
Be careful not to burn yourself because the fluid may be hot.
CAUTION
When power steering fluid is being added, use only clean fluid,
and be careful not to allow any dirt into the tank. And never use
different brands together. Avoid spilling fluid when adding it in the tank.
The power steering fluid expands greatly as its temperature rises; the
fluid level differs according to fluid temperature. Therefore, the reser-
voir 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 oillevel is between “HOT MIN ” and “HOT MAX ” on the surface of the
reservoir tank.

tighten it to the specified torque.
Aluminum wheels (if equipped)
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
approximatly 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 aluminumwheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer fluid because it could cause paint damage.
Check the level of the washer fluid at each fuel stop. If the level is low, fill
the fluid up to the neck of the reservoir.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 temperature varies
according to how much it is diluted, as indicated below.
