4. Open drain valve (Figure 7-14) and drain coolant into a
suitable container.
5. Close the drain valve once the system is completely
drained.
Filling the Cooling System
See the engine manufacturer’s manual for antifreeze and
coolant additive recommendations. Refer to the operator
manual for detailed cooling system fill instructions. Add
coolant to FULL (COLD) LEVEL as determined on checks
per the schedule in the engine owner’s manual.
1. Fully open one bleed valve located on top coolant tube
and four bleed screws: two located on the bracket
between the two cooling fins, one on each side, and two
on the outer corners of the largest fin.
2. Fill cooling system through deaeration tank fill cap to
FULL (COLD) LEVEL mark on sight gauge. Coolant
system capacity is approximately 25 gallons (94.6 liters).
3. Observe and close bleed valves once clear coolant
appears at the bleed valves.
4. Continue adding coolant until the level is at the FULL
(COLD) mark.
NOTE: Maximum fill rate is 3 GPM (11.3 liters/min).
5. Install fill cap and run engine until at normal operating
temperature.
6. Look for coolant leaks while engine is running; correct if
found.
7. Stop engine, wait until engine is cool, and refill cooling
system to FULL (COLD) level mark.
Supplemental Coolant Additive must be added to the cooling
system to prevent liner pitting and for scaling protection.
Check SCA concentration according to the schedule in the
engine manufacturer’s operator manual and per warnings,
cautions and instructions in the engine manufacturer’s
service manual.

CAUTION!
Engine Damage!
The required coolant level must be maintained to prevent
engine damage.
Do not remove the deaeration tank fill cap from a hot
engine. Allow the engine to cool below 50°C (120° F)
before adding coolant.
Do not add cold coolant to a hot engine. Engine castings
can be damaged. Allow the engine to cool below 50°C
(120°F) before adding coolant.
Coolant is toxic. Do not ingest. If not reused, dispose of in
accordance with all local and other applicable
environmental regulations.
CAUTION!
Engine Damage!
The required Supplemental Coolant Additive (SCA)
concentration must be maintained to prevent engine
damage.
