WARNING
q
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.
q
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 and
remove it carefully.
1. Open the door at the rear left of the machine, and check if
the coolant in sub-tank (1) (shown in the diagram on the
right) is between the FULL and LOW marks. If the coolant
level is low, add coolant to the FULL level through the filler
port of sub-tank (1).
2. After adding coolant, tighten the cap securely.
3. If the sub-tank becomes empty, there is probably coolant
leakage. After checking, repair any abnormality immedi-
ately. If no abnormality is found, check the level of the cool-
ant in the radiator. If it is low, add Non-Amine Engine
Coolant (AF-NAC) of the same density in the radiator to the
Non-Amine Engine Coolant (AF-NAC) density table in
"CLEAN INSIDE OF COOLING SYSTEM (4-17)", then add
Non-Amine Engine Coolant (AF-NAC) to the sub-tank.
4. When the inside of sub-tank (1) is dirty and the coolant level
cannot be checked, see "CLEAN INSIDE OF COOLING
SYSTEM (4-17)".
