6) 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. It is
recommended to use engine oil of SG, SH, SJ, SL or
SM grade. Select the appropriate oil viscosity
according to the proper engine oil viscosity chart [A].
NOTE
Engine oil capacity is specified as the
following.
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 specification
Oil pan capacity: About 3.7 liters (7.8 / 6.5 US /
lmp pt.)
Oil filter capacity: About 0.2 liter (0.4 / 0.3 US /
lmp pt.)
Others: About 0.3 liter (0.6 / 0.5 US / lmp pt.)
Total: About 4.2 liters (8.9 / 7.4 US / lmp pt.)
7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for 3 minutes. Stop it and wait
another 5 minutes before checking oil level. Add oil,
as necessary, to bring oil level to FULL level mark (1)
on dipstick.
Engine Coolant ChangeS6RW0D0206005
Change engine coolant with new one referring to
“Cooling System Flush and Refill in Section 1F”.
Exhaust System InspectionS6RW0D0206006
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 floor carpet.
• Any defects should be fixed at once.
Spark Plug ReplacementS6RW0D0206007
Replace spark plugs with new ones referring to “Spark
Plug Removal and Installation in Section 1H”.

Thermostat Removal and InstallationS6RW0D1606007
Removal
1) Drain coolant referring to “Cooling System Draining”.
2) Remove intake manifold referring to “Intake Manifold
Removal and Installation in Section 1D”.
3) Disconnect water hose (1) and heater hose (2) from
each pipe.
4) Remove thermostat case (3) with thermostat cap (4)
and water inlet pipe (5).
5) Remove water inlet pipe with thermostat cap from
thermostat case.
6) Remove thermostat from thermostat case (3).
Installation
Reverse removal procedure for installation noting the
following points.
• Install thermostat (5) to thermostat case (2) by
aligning air bleed valve (4) of thermostat with mark (3)
of thermostat case and, then install thermostat cap (1)
to thermostat case.
• Use new O-rings when installing.
• Refill cooling system referring to Step 7) to 17) of
“Cooling System Flush and Refill”.
• Verify that there is no coolant leakage at each
connection.
Thermostat InspectionS6RW0D1606008
• Make sure that air bleed valve (1) of thermostat is
clean.
• Check to make sure that valve seat (2) is free from
foreign matters which would prevent valve from
seating tight.
• Check thermostat seal (3) for breakage, deterioration
or any other damage.
• Check thermostatic movement of wax pellet as
follows:
a. Immerse thermostat (1) in water, and heat water
gradually.
b. Check that valve starts to open at specific
temperature.
Temperature at which valve begins to open
80 – 84 °C (176 – 183 °F)
Temperature at which valve become fully open
95 – 97 °C (203 – 206 °F)
Va l v e l i ft
More than 8 mm (0.31 in.) at 95 °C (203 °F)
If valve starts to open at a temperature substantially
below or above specific temperature, thermostat unit
should be replaced with a new one. Such a unit, if
reused, will bring about overcooling or overheating
tendency.

Exhaust System
General Description
Exhaust System DescriptionS6RW0D1B01001
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case, exhaust
pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels of
Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
Diagnostic Information and Procedures
Exhaust System CheckS6RW0D1B04001
WARNING!
To avoid the danger of being burned, do not touch the exhaust system when the system is hot. Any
service on the exhaust system should be performed when the system is cool.
At every interval of periodic maintenance service, and when 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 connection, dent and damage.
• If bolts or nuts are loosened, tighten them to specified torque referring to “Exhaust System Components”.
• Check nearby body areas damaged, missing, or mispositioned part, open seam, hole connection or any other
defect which could permit exhaust fumes to seep into vehicle.
• Make sure that exhaust system components have enough clearance from underbody to avoid overheating and
possible damage to vehicle underbody.
• Any defect should be fixed at once.

Reassembly
WARNING!
• When taking warmed final driven gear out
of vessel, use tongs or the like. Taking out
it with bare hand will cause severe burn.
• While installing warmed final driven gear,
use oven glove such as leather glove.
Picking up it with bare hand may cause
burn.
CAUTION!
Do not leave final driven gear in boiling water
for longer than 5 min. Overheating the gear
may cause strength reduction of gear.
1) Put final driven gear in water vessel, heat and
remove when it boils, then remove moisture.
NOTE
After removing moisture on final driven gear,
install final driven gear to differential case as
quickly as possible.
