7. Remove the oil filter with an oil filter wrench.
8. Before installing a new oil filter, apply a
thin coat of engine oil to the seal.
9. Clean the rubber seal seating area of
the bottom of engine and install the oil
filter by hand turning. Be careful not to
twist or damage the seal.
10. Tighten the oil filter by the amount
indicated in the following table after the
seal makes contact with the bottom of engine. Oil filter color Part number
Amount of
rotation
Black 15208AA100 1 rotation
CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire.
11. Reinstall under cover.
12. Pour engine oil through the filler neck. Oil capacity (guideline): 4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only 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 temperature of the oil
and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you must use the level gauge to confirm that
the level is correct.
13. Start the engine and make sure that no
oil leaks appear around the filter
’s rubber
seal and drain plug.
14. 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 engineoil.
CAUTION
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire.

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.
NOTE (turbo model only)
The cap (without tabs) on top of the
radiator does not need to be removed.
To add coolant, remove the cap (with
tabs) on the coolant tank on top of theengine.
4. Install the under cover.Non-turbo models
1) Fill up to this level
Turbo models
1) Fill up to this level
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.
Guideline of coolant quantity (including
coolant in reservoir tank): Non-turbo models:MT: 7.2 US qt (6.8 liters, 6.0 Imp qt)
AT: 7.1 US qt (6.7 liters, 5.9 Imp qt)
Turbo models: 8.5 US qt (8.0 liters, 7.0 Imp qt)

The alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires that belt tension be correct.
To check the tension of the front side belt,
place a straightedge (ruler) across two
adjacent pulleys (alternator and crank
pulley) and apply a force of 22 lbs (98 N,
