NOTICE
NEVER pour cold coolant into a hot
engine.

with filler port notches (Figure 18, (3))
and tighten filler cap (Figure 18, (1))
firmly.
NOTICE
ALWAYS tighten reservoir cap securely
after checking reservoir. Steam can
spray out during engine operation if the
cap is loose.
Note: The coolant level rises in the
reservoir during operation. After
stopping the engine, the coolant
will cool down and the extra
coolant will return to reservoir.

6. Remove reservoir cap (Figure 19, (4))
to add coolant if necessary. Do not add
water.
7. Replace filler cap and tighten it firmly.
Failure to do so will cause water
leakage.
Reservoir Capacity

8. Check the rubber hose (Figure 19, (1))
connecting the reservoir to
reservoir / heat exchanger. Replace if
damaged.
Note: If the coolant runs low too often
or the coolant level in reservoir
drops without any change in the
level in the reservoir, there may
be water or air leaks in the
cooling system. See your
authorized Yanmar dealer or
distributor.
