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.

NOTE
For detail of coolant specification, refer to
“Coolant Description”.

1) Remove radiator cap when engine is cool as follows.
a) Turn cap counterclockwise slowly until it reaches
a “stop” (Do not press down while turning it).
b) Wait until pressure is relieved (indicated by a
hissing sound) then press down on cap and
continue to turn it counterclockwise.
2) With radiator cap removed, run engine until upper
radiator hose is hot (this shows that thermostat is
open and coolant is flowing through system).
3) Stop engine and drain coolant from radiator drain
plug (1).
4) Close radiator drain plug. Add water until system is
filled and run engine until upper radiator hose is hot
again.
5) Repeat Steps 3) and 4) several times until drained
liquid is nearly colorless.
6) Close radiator drain plug (1) tightly.7) Remove reservoir cap (2) and reservoir (1).
8) Pour out any fluid, scrub and clean inside of
reservoir with soap and water.
Flush it well with clean water and drain, Reinstall
reservoir.
9) Fill reservoir with coolant up to “FULL” level mark (3).
10) Install reservoir cap (2) on reservoir.
11) Fill radiator with coolant up to bottom of radiator filler
neck and install radiator cap, making sure that the
ear of cap lines is parallel to radiator.
12) Run engine at idle speed.
13) Run engine until radiator fan motor is operated.
14) Stop engine and wait until engine comes cooled
down to help avoid danger of being burned.
15) Add coolant to radiator up to bottom of radiator filler
neck, and install radiator cap, making sure that the
ear of cap lines is parallel to radiator.
16) Repeat Step 12) through 15).
17) Confirm that reservoir coolant level is “FULL” level
mark (3). If coolant is insufficient, repeat Step 9) and
10).
Cooling Water Pipes or Hoses Removal and
Installation
S6RW0D1606006
Removal
1) Drain coolant referring to “Cooling System Draining”.
2) To remove these pipes or hoses, loosen clamp on
each hose and pull hose end off.
Installation
Install removed parts in reverse order of removal
procedure, noting the following.

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.
