METHOD FOR CHECKING COOLANT LEVEL, ADDING COOLANT
k k
WARNING
• Do not open the radiator cap unless necessary. When checking the coolant level, check the sub-
tank when the engine is cold.
• Immediately after the engine is stopped, the coolant is still hot and the pressure is accumulated in
the radiator. If the cap is removed in this condition, it is dangerous that you may get burn injury.
Always wait for the temperature to go down, turn the cap slowly to release the pressure, then re-
move the cap with care.
1.
Open the door on the rear left side of the machine.
NOTICE
If the sub-tank is empty, leakage of coolant should be
suspected. After checking, repair any abnormality im-
mediately.
REMARK
If the inside of sub-tank is so dirty that you cannot check
the coolant level, see “METHOD FOR CLEANING INSIDE
OF COOLING SYSTEM”.
2.
Check sub-tank (1).
If the coolant level is within the range between FULL and
LOW, the coolant amount is at a proper level.
If the coolant level is below LOW, add coolant to FULL lev-
el through the filler port of sub-tank (1).
3.
After refilling with coolant, tighten the cap securely.
4.
Check the coolant level in the radiator. If the coolant level
is low, add Non-Amine Engine Coolant (AF-NAC) of the
same density as Non-Amine Engine Coolant (AF-NAC) in
the radiator, and then add it to the sub-tank.
