Operation & Maintenance Manual ENGINE OPERATION
Do not mix antifreezes from different manufacturers.
Do not mix the coolant with different concentrations.
Do not add antirust which is not recommended by us.
As insuff cient coolant concentration may cause corrosion or freezing.
However, an excessive concentration may degrade the cooling
performance. Mix coolant with 40% antifreeze and 3~5% additives
(DCA4) to prevent corrosion.
13. Operate the engine at idle after starting. When cooling fan is running and coolant is
circulated, remove radiator cap and replenish coolant through the inlet.
14. Replenish coolant until the cooling fan rotates 3 ~ 5 times.
15. Replenish coolant to the upper limit of the supplementary tank and then install
radiator cap.
16. Operate the engine at idle until the cooling fan rotates 2 ~ 3 times.
17. Shut down the engine and wait until the engine and radiator are cooled.
18. After checking the coolant level in the supplementary tank, replenish coolant until the
tank level stays between the upper and lower limit without changing.
After replenishing coolant, check the coolant level of the supplementary
tank for at least two or three days.
Discard exchanged coolant to the regulations set forth by the relevant
authorities. Disposing of exchanged coolant into the ground, sewers,
drains, rivers or the sea will cause serious environmental pollution.
