CHECK COOLANT LEVEL, ADD COOLANT
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
hazard of burns. Wait for the temperature to go down, then turn the cap slowly to release the pressure
and remove it carefully.
1. Check that the coolant is between the FULL and LOW
marks on the sight gauge of sub tank (1). If the level is low,
open the cap of sub tank (1) and add water through water
filler (2) to the FULL level.
2. After adding coolant, tighten the cap securely.
3. If sub-tank (1) is empty, check for water leakage, then
check the coolant level in the radiator. If the coolant level is
low, add water to the radiator, then add water to sub-tank
(1).
If the volume of coolant added is more than usual, check
for possible leakage.
Confirm that there is no oil in the coolant.
