ENGINE COOLANT REPLACEMENT

1. Drain the engine coolant by removing the drain plug and
then the radiator cap.
2. Remove the drain plug from the cylinder block to drain
the engine coolant.
3. Remove the reserve tank to drain the engine coolant.
4. When the engine coolant has drained, pour in water from
the radiator cap to clean the engine coolant line.
5. Coat the thread of the cylinder block drain plug with the
specified sealant and tighten to the specified torque.
Specified sealant:
6. Securely tighten the radiator drain plug.
7. Install the reserve tank.
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:
Quantity: 6
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

Measure the temperature and specific gravity of the engine
coolant to check the antifreeze concentration.
Standard value: 30–60% (allowable concentration range)
