3.3.1.2 CHECKS BEFORE STARTING
Always check the items in this section before starting the engine each day.
CHECK COOLANT LEVEL, ADD COOLANT
WARNING
• Do not open the radiator cap unless necessary. When checking the coolant, always wait for the engine
to cool down and check the sub tank.
• Immediately after the engine is stopped, the coolant is at a high temperature and the radiator is under
high internal pressure. If the cap is removed to check the coolant level in this condition, there is a haz-
ard of burns. Wait for the temperature to go down, then turn the cap slowly to release the pressure be-
fore removing it.
1. Open the engine rear cover and cooling cover. For de-
tails, see Section "3.2.10 COOLING COVER".
2. Check that the cooling water level is between the FULL
and LOW range on sub tank (1). If the water level is low,
add water through the water filler port of sub tank (1) to
the FULL line.
3. After adding water, tighten the cap securely.
4. If the reserve tank is empty, check for leakage of water,
then check the radiator water level. Add water to the radi-
ator if necessary, then add water to the reserve tank.
