at the specified mixing ratio to let the air be
discharged from the radiator.
NOTE
Use recommended genuine antifreeze entitled
"Engine coolant- Specifications"
CAUTION
– Do not mix antifreezes from different manufactur-
ers.
– Do not mix the coolant with different concentra-
tions.
– Do not add antitrust which is not recommended by
us.
– As insufficient coolant concentration may cause
corrosion or freezing, on the other hand, an ex-
cessive concentration may degrade the cooling
performance. Mix coolant with 40% antifreeze and
3~5% additives (DCA4) to prevent corrosion.
– Operate the engine at idle after starting.
When cooling fan is running and coolant is
circulated, remove radiator cap and replen-
ish coolant through the inlet.
– Replenish coolant until the cooling fan ro-
tates 3 ~ 5 times.
– Replenish coolant to the upper limit of the
supplementary tank and then install radiator
cap.
– Operate the engine at idle until the cooling
fan rotates 2 ~ 3 times.
– Stop the engine and wait until the engine
and the radiator are cooled.
– After checking the coolant level in the sup-
plementary tank, replenish coolant until the
tank level stays between the upper and low-
er limit without changing.
NOTE
After replenishing coolant, check the coolant
level of the supplementary tank for at least two
or three days.
