Check the coolant level in reservoir tank (5).
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 of the same
density according to the coolant density table in “METHOD
FOR USING FUEL, COOLANT AND LUBRICANTS AC-
CORDING TO AMBIENT TEMPERATURE” to FULL of the
level through the filler port of reservoir tank (5).
NOTICE
• If the reservoir tank is empty, leakage of coolant
should be suspected. After checking, repair any
abnormality immediately.
If no abnormality is found, check the level of the
coolant in the radiator. If it is low, add coolant to
the radiator first, and add it to the reservoir tank.
• If the inside of reservoir tank is so dirty that you
cannot check the coolant level, clean the inside of
cooling system by referring to “METHOD FOR
CLEANING INSIDE OF COOLING SYSTEM”.
