CAUTION:
When replenishing oil, it does not matter if the oil to be added is a different brand from that in the en-
gine; however, use oil having the API standard and SAE viscosity No. designated by SUBARU.

C: CAUTION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Be careful not to burn yourself, because each part on 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 connectors of sensors or units, be sure to disconnect the ground cable from battery.

Engine Oil
LUBRICATION
3. Engine Oil
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 properly
orientated.
4) Remove it again and check the reading. If the
engine oil level is below “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 return to the oil pan before checking
the level.
NOTE:
To prevent overfilling of engine oil, do not add oil
above “F” line when the engine is cold.
B: REPLACEMENT
1) Open the engine oil filler cap for quick draining of
engine oil.
2) Lift-up the vehicle.
3) Drain engine oil by loosening the engine oil drain
plug.
NOTE:
Prepare the container for draining of engine oil.
4) Tighten the engine oil drain plug after draining
engine oil.
NOTE:
Use a new drain plug gasket.
Tightening torque:
44 N·m (4.5 kgf-m, 33 ft-lb)
5) Using engine oil of proper quality and viscosity,
fill engine oil through the oil filler duct to the upper
level on level gauge. Make sure that the vehicle is
parked on a level surface when checking oil level.
Recommended oil:
Refer to “SPECIFICATION” for the recom-
mended oil.
Engine oil capacity
Refer to “SPECIFICATION” for the engine oil
capacity.
6) Close the engine oil filler cap.
7) Start the engine and warm it up for a time.
8) After the engine stops, recheck the oil level. If
necessary, add engine oil up to the upper level on
level gauge.

1. TIP CLEARANCE
Measure the tip clearance of rotors. If the clearance
exceeds specification, replace the rotors as a
matched set.
Tip clearance:
Specification
0.04 — 0.14 mm (0.0016 — 0.0055 in)

rear chain cover rotor housing. If the clearance ex-
ceeds the standard value, replace the outer rotor.
Case clearance:
Specification

3. SIDE CLEARANCE
Measure the clearance between oil pump inner ro-
tor and rear chain cover. If the clearance exceeds
