ENGINE OPERATION Operation & Maintenance Manual
The recommended mixing ratio allows coolant to prevent corrosion of
the engine eff ciently and to maintain the best engine performance for
a long period. Using contaminated water or unspecif ed antifreeze or
additives may cause critical faults in the cooler.

Checking the Coolant
If the radiator cap is opened to exchange or replenish coolant while the
engine is overheated, hot water will spurt out and may cause serious
burns. If it is absolutely necessary to open the radiator cap while the
engine is overheated, wrap the radiator cap with a cloth and slowly open
the cap in two steps until the steam pressure has been released from the
inside. After the steam pressure has been completely released, remove
the radiator cap.
1. Make sure that the engine and radiator are cooled.
2. Check the level in the supplementary tank.
3. If the coolant level indicates between the upper limit and the lower limit on the
supplementary tank, it means that the coolant volume is normal.
4. If there is insufficient coolant, replenish it.
5. Open the radiator cap and check the condition of the coolant. If the coolant cap
is contaminated or insufficient, measure the coolant concentration. If the coolant
concentration is outside the specified range, exchange the coolant.
