ENGINE COOLING -
On-vehicle Service

8. Remove the air bleed bolt and replace the seal washer.
9. Fill the radiator until the engine coolant flows from the
air bleed bolt section, and then close the air bleed bolt.
10. Slowly pour the engine coolant into the mouth of the
radiator until the radiator is full, and pour also into the
reserve tank up to the FULL line.
Recommended antifreeze:
HIGH QUALITY ETHYLENE GLYCOL ANTIFREEZE
COOLANT
Quantity:
<4G6, 6A1> 6 L
<4D6> 8 L
NOTE
For Norway, the non-amine type of antifreeze should be
used.
11. Install the radiator cap securely.
12. Start the engine and warm the engine until the thermostat
opens. (Touch the radiator hose with your hand to check
that warm water is flowing.)
13. After the thermostat opens, race the engine several times,
and then stop the engine.
14. Cool down the engine, and then pour engine coolant
into the reserve tank until the level reaches the FULL
line. If the level is low, repeat the operation from step
11.
CONCENTRATION MEASUREMENT
14100110146
Measure the temperature and specific gravity of the engine
coolant to check the antifreeze concentration.
Standard value: 30 - 60 % (allowable concentration range)
RECOMMENDED ANTIFREEZE
Antifreeze Allowable concentration
HIGH QUALITY ETHYLENE
GLYCOL ANTIFREEZE COOLANT
30 - 60 %
Caution
If the concentration of the antifreeze is below 30 %, the
anti-corrosion property will be adversely affected. In
addition, if the concentration is above 60 %, both the
anti-freezing and engine cooling properties will decrease,
affecting the engine adversely. For these reasons, be
sure to maintain the concentration level within the
specified range.
