Fill Cooling System
CAUTION: Prevent possible injury from hot,
spraying uids. Shut off engine. Remove ller
cap only when cool enough to touch with bare
hands. Slowly loosen cap to relieve pressure
before removing completely.
IMPORTANT: Avoid mixing different brands or types
of coolant. Coolant manufacturers engineer
their coolants to meet certain specications
and performance requirements. Mixing
different coolant types can degrade coolant
and machine performance.
Use only permanent-type, low silicate, ethylene
glycol antifreeze in coolant solution. Other
types of antifreeze may damage cylinder seals.
Follow directions on container for correct
mixture ratio.
FREEZING TEMPERATURES: Fill with permanent-type,
low silicate, ethylene glycol antifreeze (without stop-leak
additive) and clean soft water.
Remove surge tank cap (1) to relieve pressure. Fill
surge tank to above the full hot mark. See Diesel Engine
Coolant. (Section 3-1.) Install surge tank cap.

Deaeration
The cooling system requires several warm-up and cool
down cycles to deaerate. It will NOT deaerate during
normal operation. Only during warm-up and cool down
cycles will the system deaerate.
1. Start engine. Run engine until coolant reaches a warm
temperature.
2. Stop engine. Allow coolant to cool.
3. Check coolant level at surge tank. See Check Engine
Coolant Level. (Section 3-4.)

4. Repeat steps 1—3 until surge tank coolant level is
repeatedly at the same level (stabilized).
NOTE: Coolant level MUST BE repeatedly checked after
all drain and rell procedures to ensure that all
air is out of the system, which allows the coolant
level to stabilize. Coolant level should only be
checked when the engine is cold.
5. If necessary, ll surge tank to above the MIN COLD
mark.
6. Install surge tank cap.
