Checking The Engine Oil And Engine Coolant - Yanmar 8LV320 Operation Manual

BEFORE YOU OPERATE
4. Tighten filler cap.
Always tighten the coolant tank cap
securely after checking the coolant tank.
Steam can spray out during engine
operation if the cap is loose.
The coolant level rises in the coolant reservoir
tank during operation. After stopping the engine,
the coolant will cool down and the extra coolant
will return to the coolant tank.
5. Check the coolant level in the coolant reservoir
tank. The level should be at the FULL mark.
Add coolant if necessary.
Never pour cold coolant into a hot engine.

6. Remove coolant reservoir tank cap to add
coolant if necessary.
7. Replace filler cap and tighten it firmly. Failure to
do so will cause water leakage.
Coolant Reservoir Tank Capacity
1.25 l (2.6 pt)
8. Check the rubber hose connecting the coolant
reservoir tank to the coolant tank/heat
exchanger. Replace if damaged.
Note:
• The level of the coolant tank often decrease.
• The level of the reservoir tank does not change.
In these cases, there may be water or air leaks in
the cooling system.
Contact your authorized Yanmar Marine dealer or
distributor.

CHECKING THE ENGINE OIL
AND ENGINE COOLANT
When engine oil or coolant is supplied for the first
time or when they must be replaced, conduct a trial
operation of the engine and check the quantity of
engine oil and coolant. The trial engine operation
will send the engine oil and coolant to the
passages, so the engine oil and coolant levels will
drop. Check and resupply as necessary:
1. Approximately 5 minutes after stopping the
engine, remove the oil dipstick (2, Figure 5)
and check the oil level. Add oil if the level is too
low.
2. Add coolant to the coolant reservoir tank to stay
within the upper or lower limit (Figure 7).
