Engine Oil
PERIODIC MAINTENANCE SERVICES
3. Engine Oil
A: REPLACEMENT
1) Open the engine oil filter cap for quick draining of
the engine oil.
2) Drain the engine oil by removing the engine oil
drain plug.
3) Tighten the engine oil drain plug after draining
the engine oil.
NOTE:
Use a new drain plug gasket.
Tightening torque:
44 N·m (4.5 kgf-m, 33 ft-lb)
4) Fill engine oil through the level gauge up to the
center between the upper level and the lower level.
Place the vehicle on a level surface when checking
oil level. Use engine oil of the proper quality and
viscosity, selected in accordance with the following.
Recommended oil:
Refer to “RM” section.

ommended Materials.>
Engine oil capacity
When replacing engine oil and oil filter
Upper level
Approx. 5.7 2 (6.0 US qt, 5.0 Imp qt)
Lower level:
Approx. 4.7 2 (5.0 US qt, 4.10 Imp qt)
When replacing engine oil only
Upper level:
Approx. 5.5 2 (5.8 US qt, 4.8 Imp qt)
Lower level:
Approx. 4.5 2 (4.8 US qt, 4.0 Imp qt)
The proper viscosity oil helps the engine maintain
its ideal temperature, and cranking speed in-
creased by reducing viscosity friction in hot condi-
tion.
CAUTION:
When replenishing oil, it does not matter if the
oil to be added is a different brand from that in
the engine; however, use oil having the API
standard and SAE viscosity No. designated by
SUBARU.
NOTE:
If the vehicle is used in areas with very high temper-
atures or for other heavy duty applications, the fol-
lowing viscosity oils must be used:API Standard:
SM SAE Viscosity No.: 30, 40, 10W-50, 20W-40,
20W-50
5) Close the engine oil filler cap.
6) Start the engine and warm it up for a time.
7) Stop the engine to inspect the oil level again.

B: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and in the
proper orientation.
4) Remove it again and check the oil reading.
If the engine oil level is below the “L” line, add oil to
bring the level up to the “F” line. To prevent overfill-
ing the engine oil, do not add oil above the “F” line
when the engine is cold.
5) Check whether it is notably dirty, or there is cool-
ant or gasoline mixed in. Replace if it is notably
dirty. If there is coolant or gasoline mixed in, check
the engine.
6) After pouring in engine oil, run the engine for
several minutes, then stop it. Wait for several min-
utes until the oil has returned to the oil pan.

Engine Oil Filter
PERIODIC MAINTENANCE SERVICES
4. Engine Oil Filter
A: REPLACEMENT
1) Remove the service hole cover clip.
2) Rotate the service hole cover in the direction of
the arrow.
3) Remove the oil filter using ST.
ST 49857000 OIL FILTER WRENCH (Outer
diameter: 80 mm (3.15 in))
4) Obtain a new oil filter and apply a thin coat of en-
gine oil to the seal rubber.
5) Install the oil filter by turning it by hand, while be-
ing careful not to damage seal rubber. Then, after
the seal rubber touches the oil cooler, tighten it a
further 3/4 turn.
CAUTION:
Do not tighten excessively, because this can
cause oil leaks.
6) After installing the oil filter, run the engine and
make sure that no oil is leaking around seal rubber.
NOTE:
The filter element and filter case are permanently
jointed; therefore, interior cleaning is not neces-
sary.
7) Check the engine oil level.

5. Spark Plug
A: REPLACEMENT
1) Remove the battery and battery carrier.
2) Remove the air cleaner case.
3) Detach the connector from ignition coil.
4) Remove the ignition coil.
5) Remove the spark plug with a spark plug socket.
6) Tighten the new spark plug lightly with hand, and
then secure with a spark plug socket to the speci-
fied torque.
Recommended spark plug:
NGK: ILFR6B
Tightening torque:
21 N·m (2.1 kgf-m, 15.2 ft-lb)
7) Tighten the ignition coil.
Tightening torque:
16 N·m (1.6 kgf-m, 11.7 ft-lb)
NOTE:
•Be sure to place the gasket between the cylinder
head and spark plug.
•If the torque wrench is not available, tighten the
spark plug until gasket contacts cylinder head; then
tighten further 1/4 to 1/2 turns.

Cooling System
PERIODIC MAINTENANCE SERVICES
9. Cooling System
A: INSPECTION
1) To check the radiator for leakage, fill it with en-
gine coolant, and attach the radiator cap tester (A)
to the filler neck, and apply pressure. Check the fol-
lowing points:
157 kPa (1.6 kg/cm2, 23 psi)
NOTE:
•Hose joints and other connections for leakage
•Each portion of radiator for leakage
•Be particularly careful not to deform the filler
neck of radiator when installing and removing the
tester and after testing.
•When performing this check, be sure to keep the
engine stationary and fill radiator with coolant.
•Wipe off check points before applying pressure.
•Use care not to spill coolant when detaching
tester from radiator.
2) Check the radiator cap valve open pressure us-
ing radiator cap tester.
NOTE:
Rust or dirt on the cap may prevent valve from func-
tioning normally:be sure to clean the cap before
testing.
Raise the pressure until the needle of gauge stops
and see if the pressure can be retained for five to
six seconds. The radiator cap is normal if a pres-
sure above the service limit value has been main-
tained for this period.
Radiator cap valve open pressure
Standard:
93 — 123 kPa (0.95 — 1.25 kg/cm2, 14 — 18
psi)
Service limit:
83 kPa (0.85 kg/cm2, 12 psi)
3) Start the engine, and then check it does not
overheat or it is cooled excessively. If it overheats
or it is cooled excessively, check the cooling sys-
tem.
