Engine Oil and Filter Change

S5JB0A0206003

WARNING

!

 

• New and used engine oil can be 

hazardous.
Be sure to read “General Precautions in 
Section 00” and observe what in written 
there.

• Steps 1) – 7) must be performed with 

ENGINE NOT RUNNING. For Step 8), be 
sure to have adequate ventilation while 
engine is running.

 

Before draining engine oil, check engine for oil leakage. 
If any evidence of leakage is found, make sure to correct 
defective part before proceeding to the following work.

1) Drain engine oil by removing drain plug.
2) After draining oil, wipe drain plug clean. Reinstall 

drain plug.

Tightening torque
Engine oil drain plug (a):  35 N·m (3.5 kgf-m, 25.5 
lb-ft)

3) Loosen oil filter by using oil filter wrench (special 

tool).

Special tool
(A):  09915–40611

4) Apply engine oil to new oil filter O-ring.

5) Screw new filter on oil filter stand by hand until the 

filter O-ring contacts the mounting surface.

CAUTION

!

 

To tighten oil filter properly, it is important to 
accurately identify the position at which filter 
O-ring first contacts the mounting surface.

 

6) Tighten oil filter (1) 3 / 4 turn from the point of contact 

with the mounting surface using an oil filter wrench 
(2).

Tightening torque
Oil filter (a):  14 N·m (1.4 kgf-m, 10.5 lb-ft)

7) Replenish oil until oil level is brought to FULL level 

mark on dipstick. (oil pan and oil filter capacity). The 
filler inlet is at the top of the cylinder head cover. 
Use only engine oil of SG, SH, SJ, SL or SM grade.
Select the appropriate oil viscosity according to the 
chart [A].
It is highly recommended to use SAE 5W-30 oil.
However, SAE 10W-30 oil is usable for ambient 
temperatures above –18 

°C (0 °F).

NOTE
Engine oil capacity is specified below. 
However, note that the amount of oil required 
when actually changing oil may somewhat 
differ from the data depending on various 
conditions (temperature, viscosity, etc.)

 

Engine oil specifications (M16 Engine)
Oil pan capacity: About 4.0 liters (8.4 US pt. / 7.0 
lmp pt.)
Oil filter capacity: About 0.2 liters (0.4 US pt. / 0.3 
lmp pt.)
Others: About 0.3 liters (0.6 US pt. / 0.5 lmp pt.)
Total: About 4.5 liters (9.5 US pt. / 7.9 lmp pt.)

Engine oil specifications (J20 Engine)
Oil pan capacity: About 5.0 liters (10.5 US pt. / 8.8 
lmp pt.)
Oil filter capacity : About 0.2 liters (0.4 US pt. / 
0.3 lmp pt.)
Others: About 0.3 liters (0.6 US pt. / 0.5 lmp pt.)
Total: About 5.5 liters (11.6 US pt. / 9.6 lmp pt.)

Proper engine oil viscosity chart

8) Check oil filter and drain plug for oil leakage.
9) Start engine and run it for 3 minutes. Stop it and wait 

5 minutes before checking oil level. Add oil, as 
necessary, to bring oil level to FULL level mark (hole) 
(1) on dipstick.

Engine Coolant Change

S5JB0A0206005

WARNING

!

 

To help avoid danger of being burned, do not 
remove radiator cap while engine and 
radiator are still hot. Scalding fluid and steam 
can be blown out under pressure if cap is 
taken off too soon.

 

Change engine coolant referring to “Cooling System 
Flush and Refill in Section 1F”.

Exhaust system Inspection

S5JB0A0206006

WARNING

!

 

To avoid danger of being burned, do not 
touch exhaust system when it is still hot. Any 
service on exhaust system should be 
performed when it is cool.

 

When carrying out periodic maintenance, or the vehicle 
is raised for other service, check exhaust system as 
follows:
• Check rubber mountings for damage, deterioration, 

and out of position.

• Check exhaust system for leakage, loose 

connections, dents and damages.
If bolts or nuts are loose, tighten them to specification.

• Check nearby body areas for damaged, missing, or 

mispositioned parts, open seams, holes, loose 
connections or other defects which could permit 
exhaust fumes to seep into the vehicle.

• Make sure that exhaust system components have 

enough clearance from the underbody to avoid 
overheating and possible damage to the floor carpet.

• Any defects should be fixed at once.
