Check Coolant Level - Hitachi ZW 370-6 Operator's Manual

Check Coolant Level

--- every 10 hours (daily)
IMPORTANT:
 When refilling a long life coolant (LLC), use the
same brand product and the same mixture ratio as
already used in the machine.
 If only water is refilled, the mixture ratio in the long
life coolant (LLC) is diluted so that anti-rust and
antifreeze effect in the coolant will become diluted
and less affective.
 Refer to page 7-71 for the coolant specifications.
Check the coolant level at reservoir (1). The normal coolant
level is between the FULL and LOW marks on side surface of
reservoir (1).
In case no coolant is present in reservoir (1), add the coolant
mixture via cap hole (2) on reservoir (1).
In addition, open radiator cap (3) to check the coolant level.
Coolant level is normal if coolant is to the lower part of neck
pipe.
If needed, add the required amount of the coolant.
 When refilling a long life coolant (LLC), use the same
brand product and the same mixture ratio as already
used in the machine.
 If only water is refilled, the mixture ratio in the long life
coolant (LLC) is diluted so that anti-rust and antifreeze
effect in the coolant will become diluted and less
affective.
IMPORTANT: If the coolant level is low, EGR cooler is
heated up, and damaged.
