Valves and Cylinder Head Disassembly and
Assembly
S6RW0D1406027
Disassembly
1) For ease in servicing cylinder head, remove intake
manifold, injectors, exhaust manifold from cylinder
head.
2) Using special tools (Valve lifter), compress valve
spring and then remove valve cotters (1) also by
using special tool (Forceps).
Special tool
(A): 09916–14510
(B): 09916–14521
(C): 09916–845113) Release special tools (Valve lifter), and remove
spring retainer and valve spring.
4) Remove valve from combustion chamber side.
5) Remove valve stem seal (1) from valve guide and
valve spring seat (2).
NOTE
Do not reuse valve stem seal once
disassembled. Be sure to use new seal when
assembling.

6) Using special tool (Valve guide remover), drive valve
guide out from combustion chamber side to valve
spring side.
Special tool
(A): 09916–44910
NOTE
Do not reuse valve guide once disassembled.
Be sure to use new valve guide (oversize)
when assembling.

7) Place disassembled parts except valve stem seal
and valve guide in order so that they can be installed
in their original position.

6) Install valve to valve guide.
Before installing valve to valve guide, apply engine
oil to stem seal, valve guide bore and valve stem.
7) Install valve spring and spring retainer.
Each valve spring has top end (large-pitch end (1))
and bottom end (small-pitch end (2)). Be sure to
position spring in place with its bottom end (small-
pitch end) facing the bottom (valve spring seat side).8) Using special tools (Valve lifter), compress valve
spring and fit two valve cotters (1) into groove in
valve stem.
NOTE
When compressing the valve spring, be
carefully to free from damage in inside face
of tappet installing hole.

(C): 09916–84511
9) Install intake manifold referring to “Intake Manifold
Removal and Installation”.
10) Install fuel injectors referring to “Fuel Injector
Removal and Installation in Section 1G”.
11) Install exhaust manifold referring to “Exhaust
Manifold Removal and Installation in Section 1K”.

Cylinder Head InspectionS6RW0D1406029
• Remove all carbon deposits from combustion
chambers.
NOTE
Do not use any sharp-edged tool to scrape
off carbon deposits. Be careful not to scuff or
nick metal surfaces when decarbonizing. The
same applies to valves and valve seats, too.

• Check cylinder head for cracks on intake and exhaust
ports, combustion chambers, and head surface. Using
a straightedge and thickness gauge, check flatness of
gasketed surface at a total of 6 locations. If distortion
limit is exceeded, correct gasketed surface with a
surface plate and abrasive paper of about #400
(Waterproof silicon carbide abrasive paper): place
abrasive paper on and over surface plate, and rub
gasketed surface against paper to grind off high spots.
Should this fail to reduce thickness gauge readings to
within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint
is often due to warped gasketed surface: such
leakage results in reduced power output.Distortion for cylinder head surface on piston side
Limit: 0.03 mm (0.001 in.)
• Distortion of manifold seating faces:
Check seating faces of cylinder head for manifolds,
using a straightedge and thickness gauge, in order to
determine whether these faces should be corrected or
cylinder head replaced.
Distortion for cylinder head surface on intake and
exhaust manifold
Limit: 0.05 mm (0.002 in.)

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.

Diagnostic Information and Procedures
A/C System Performance InspectionS6RW0D7214001
1) Confirm that vehicle and environmental conditions
are as follows.
• Vehicle is put indoors.
• Ambient temperature is within 25 – 35 °C (77 – 95
°F).
• Relative humidity is within 30 – 70%.
• There is no wind indoors.
• HVAC unit is normal.
• Blower motor is normal.
• There is no air leakage from air ducts.
• Condenser fins are clean.
• HVAC air filter is not clogged with dirt and dust (if
equipped).
• Battery voltage is about 12 V.
• Radiator cooling fan operates normally.
2) Make sure that high pressure valve (1) and low
pressure valve (2) of manifold gauge are firmly
closed.
3) Connect high pressure charging hose (3) to high
pressure service valve (5) on vehicle and low
pressure charging hose (4) to low pressure service
valve (6).
4) Bleed the air in charging hoses (3) and (4) by
loosening their nuts respectively utilizing the
refrigerant pressure. When a hissing sound is heard,
immediately tighten nut.
CAUTION!
Do not connect high and low pressure
charging hoses in reverse.

5) Warm up engine to the normal operating
temperature and keep it at the specified idle speed.
6) Turn A/C switch ON, set blower speed selector at
maximum speed position, temperature selector at
maximum cold position, air flow selector at face
position, and air intake selector at recirculation
position. (Confirm that A/C compressor, A/C
condenser cooling fan and radiator cooling fan are
working.)
7) Wait for ten minutes to stabilize the A/C operation.
8) Open all door windows, front doors and engine hood.
9) With about 20 mm (0.8 in.) of dry bulb thermometer
(1) put right in front of center ventilation louver and a
wet and dry bulb thermometer (2) near air inlet of
HVAC unit.
