Cooling System Fill and Deaeration Procedure

CAUTION: Prevent possible injury from hot
spraying fluids. Shut off engine. Remove filler
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 specifications
and performance requirements. Mixing
different coolant types can degrade coolant
and machine performance.
Use only permanent-type low silicate ethylene
glycol base antifreeze in coolant solution. Other
types of antifreeze may damage cylinder seals.

coolant is recommended when adding new
coolant to cooling system.
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 to relieve pressure. Fill surge tank
(1) to above the full hot mark. Replace surge tank cap.
Deaeration
The cooling system requires several warmup and cool
down cycles to deaerate. It will NOT deaerate during
normal operation. Only during warmup 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.
4. Repeat steps 1—3 until surge tank coolant level is
repeatedly at the same level (stabilized).
NOTE: The level of the coolant in the cooling system
MUST BE repeatedly checked after all drain and

refill procedures to insure that all air is out of the
system which allows the coolant level to stabilize.
Check coolant level only when the engine is cold.
5. If necessary, fill surge tank to above the MIN COLD
mark.
