Engine Cooling System: 1F-6
Cooling System Flush and Refill
S4RS0A1606004
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 (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) Loosen air ventilation bolt (4) one and a half turns.
12) Fill radiator with coolant up to spilling coolant from
air ventilation bolt (4).
13) Tighten air ventilation bolt (4) to specified torque.
Tightening torque
Air ventilation bolt (a): 4.5 N·m (0.45 kg-m, 3.5
lb-ft)
14) 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.
15) Run engine at idle speed.
16) Loosen air ventilation bolt (4) one and a half turns.
17) Run engine at 2000 – 3000 rpm, and tighten air
ventilation bolt (4) to specified torque after spilling
coolant from air ventilation bolt (4).
Tightening torque
Air ventilation bolt (a): 4.5 N·m (0.45 kg-m, 3.5
lb-ft)
18) Run engine until radiator fan motor is operated.
19) Stop engine and wait until engine comes cooled
down to help avoid danger of being burned.
20) 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.
21) Repeat Step 15) through 20).
22) Confirm that reservoir coolant level is “Full” level
mark (3). If coolant is insufficient, repeat Step 9) and
10).
