Maintenance
Cooling System
WARNING
To prevent personal injury or death, do the
following when removing radiator or deaeration
cap:
•
Allow the engine to cool.
•
Wrap a thick cloth around pressure cap.
•
Partially unscrew pressure cap slowly while firmly
holding cap down, then pause to allow pressure to
release.
•
When system pressure is released, fully unscrew
pressure cap while continuing to hold cap down. Slowly
release downward pressure from pressure cap.
•
Remove cap.
WARNING
To prevent property damage, personal injury, and
/ or death, do not exceed the pressure rating on
the deaeration tank cap. Ensure that the pressure
rating of the deaeration tank cap matches that
listed on the side of the tank, or the tank may
burst.
CAUTION
To prevent property damage, if the coolant should
get extremely low and the engine very hot, let the
engine cool for approximately 15 minutes before
adding coolant. Then, add coolant slowly with
the engine running. Adding cold coolant to a hot
engine may crack the cylinder head or crankcase.
Never use water alone.
Make sure that coolant level is maintained between the COLD
MIN and COLD MAX lines on the deaeration tank when engine
is cold.
Gravity-Fill Coolant Method (PSI 8.8L LPG Engine)
Filling Instructions
NOTE: Using the KL5007NAV Coolant Management Tool
is the recommended procedure to fill the cooling system,
however, in some cases this tool may not be available, and
the following gravity-fill procedure may be used instead.
Contact an IC Bus or International dealer for special
instructions on filling the coolant system.
NOTE: This is a traditional gravity-fill-only method that
involves pouring or pumping the coolant into the deaeration
tank of the cooling system and using a combination of
gravity and engine operation to purge the system of air.
It may be necessary to run the engine at various speeds
for up to an hour after filling, followed by a 10 - 12 hour
cooldown and top-off, to avoid releasing a vehicle that can
be approximately 1 gallon low on coolant.
