(2) Engine coolant leaks at/around hoses or
connections.
CAUTION:
Inspection must be carried out at the side of
coolant filler tank, not at the side of radiator.
Engine should be off.

Wear working clothing, including a cap, protec-
tive goggles, and protective shoes during opera-
tion.
Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro-
tect them from dust or dirt.
Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly, and replacement.
Be careful not to burn yourself, because each
part in the vehicle is hot after running.
Be sure to tighten fasteners including bolts and
nuts to the specified torque.
Place shop jacks or rigid racks at the specified
points.
Before disconnecting electrical connectors of
sensors or units, be sure to disconnect the ground

A: 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 note the reading. If the en-
gine oil level is below the “L” line, add oil to bring
the level up to “F” line.
5) After turning off the engine, wait a few minutes
for the oil to drain back into the oil pan before
checking the level.
6) Just after driving or while the engine is warm, en-
gine oil level may show in the range between the
“F” line and notch mark. This is caused by thermal
expansion of the engine oil.
NOTE:
To prevent overfilling the engine oil, do not add oil
above the “F” line when the engine is cold.
B: REPLACEMENT
1) Open the engine oil filler cap for quick draining of
the engine oil.
2) Remove six clips.
3) Turn the service hole cover counterclockwise.
4) Drain the engine oil by loosening the engine oil
drain plug.
5) Replace the drain plug gasket.

7) Install the service hole cover.
8) Fill engine oil through the filler pipe up to upper
point on level gauge. Make sure that the vehicle is
placed level when checking oil level. Use the en-
gine oil of proper quality and viscosity, selected in
accordance with the table in figure.
Recommended oil
API classification SL, SJ with the “Energy
Conserving” logo is printed, or SH (if you
cannot obtain the oil with SL, SJ or SH
grades, you may use SG, SF grades “ENER-
GY CONSERVING” oil.)

The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.
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
classification and SAE viscosity No. designat-
ed by SUBARU.
NOTE:
If the vehicle is used in areas with very high tempera-
tures or for other heavy duty applications, the follow-
ing viscosity oils may be used: API classification: SL
or SJ or SH
SAE Viscosity No. : 30, 40, 10W-50, 20W-40, 20W-
50.
9) Close the engine oil filler cap.
10) Start the engine and warm it up for a time.
11) After the engine stops, recheck the oil level. If
necessary, add engine oil up to the upper level on
level gauge.

1) Wipe and clean the oil filter matching surface on
cylinder block and oil cooler.
2) Get a new oil filter and apply a thin coat of engine
oil to the seal rubber.
CAUTION:
Be careful not to use the oil filter 80 mm (3.15 in)
in diameter to turbo model.
3) Install the oil filter by turning it by hand, being
careful not to damage seal rubber.
Tighten the oil filter 80 mm (3.15 in) or 65 mm
(2.56 in) in diameter by approx. 2/3 — 3/4 rotation
more after the seal rubber of oil filter comes in con-
tact with cylinder block or oil cooler.
Tighten the oil filter 68 mm (2.68 in) in diameter
by approx. 1 rotation more after the seal rubber of
oil filter comes in contact with cylinder block or oil
cooler.
CAUTION:
Do not tighten excessively, or oil may leak.
C: INSPECTION
1) 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.
2) Check the engine oil level.
