Cooling System Flush and RefillS7RS0B1606005
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 up per 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 (1) and remove cap (2) from
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 ca p, making sure that the
ear of cap lines is parallel to radiator.
16) Repeat Step 12) through 15).
17) Confirm that reservoir cool ant level is “Full” level
mark (3). If coolant is insu fficient, repeat Step 9) and
10).

Section 7B” or “Compressor Drive Belt Inspection and
Adjustment in Section 7B”. • Refill cooling system referrin
g to Step 7) to 22) of
“Cooling System Flush and Refill”.
• Verify that there is no coolant leakage at each connection.
Thermostat InspectionS7RS0B1606008
• Make sure that air bleed valve (1) of thermostat is clean.
• Check to make sure that va lve 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 °F)
Va l v e l i ft
More than 8 mm 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 ov ercooling or overheating
tendency.
